NNSA Policy Letter: NAP 14.4-A Date: April 5, 2006 TITLE: Open Public Unrestricted Access Information Group Protection Profile 1. OBJECTIVE. Establish requirements for the protection of National Nuclear Security Administration (NNSA) Open Public Unrestricted Access information when information systems are used to collect, create, process, transmit, store, and disseminate this information. 2. APPLICABILITY. This NNSA Policy (NAP) applies to all entities, Federal or contractor, which collects, create, process, transmit, store, and disseminate NNSA information. a. NNSA Elements. NNSA Headquarters Organizations, Service Center, Site Offices, NNSA contractors, and subcontractors are, hereafter, referred to as NNSA elements. b. Information System. This NAP applies to any information system that collects, creates, processes, transmits, stores, and disseminates unclassified or classified information for NNSA. This NAP applies to any information system life cycle, including the development of new information systems, the incorporation of information systems into an infrastructure, the incorporation of information systems outside the infrastructure, the development of prototype information systems, the reconfiguration or upgrade of existing systems, and legacy systems. In this document, the term(s) "information system", Target of Evaluation (TOE), or "system" are used to mean any information system or network that is used to collect, create, process, transmit, store, or disseminate data owned by, for, or on behalf of NNSA or DOE. c. Deviations. Deviations from the requirements prescribed in this NAP must be processed in accordance with the requirements in Chapter E of Attachment 1 to NAP-14.A, NNSA Cyber Security Program. d. Site/Facility Management Contractors. Except for the exclusions in paragraph 2.e, the Contractor Requirements Document (CRD) Attachment 1, sets forth requirements of this NAP that will apply to site/facility management contractors whose contract includes the CRD. (1) The CRD must be included in site/facility management contracts that provide access to NNSA information systems and automated access to NNSA information. NAP 14.4-A 2 (2) The CRD does not automatically apply to other than site/facility management contractors. Any application of requirements of this Policy to other than site/facility management contractors will be communicated separately. (3) As the laws, regulations, and DOE and NNSA directives clause of site/facility management contracts states, regardless of the performer of the work, site/facility management contractors with the CRD incorporated into their contracts are responsible for compliance with the requirements of the CRD. (4) Affected site/facility management contractors are responsible for flowing down the requirements of this CRD to subcontracts at any tier to the extent necessary to ensure the site/facility management contractors’ compliance with the requirements. (5) Contractors must not flow down requirements to subcontractors unnecessarily or imprudently. That is, contractors will--- (a) Ensure that they and their subcontractors comply with the requirements of the CRD; and (b) Incur only costs that would be incurred by a prudent person in the conduct of competitive business.

e. Exclusion. The Deputy Administrator for Naval Reactors shall, in accordance with the responsibilities and authorities assigned by Executive Order 12344 (set forth in Public Law 106-65 of October 5, 1999 [50 U.S.C. 2406]) and to ensure consistency throughout the joint Navy and DOE Organization of the Naval Reactors Propulsion Program, implement and oversee all requirements and practices pertaining to this policy for activities under the Deputy Administrator’s cognizance. f.

PP INTRODUCTION This Open Public Unrestricted Information Group1 Protection Profile, hereafter called OPENPP, specifies a set of security functional and assurance requirements for the NNSA Open Public Unrestricted Access Information Group and the Information Technology (IT) products used to create, store, process, disseminate information in this Information Group. This section contains document management and overview information necessary to describe the Protection Profile (PP) for use in the National Nuclear Security Administration (NNSA). The PP identification provides the labeling and descriptive information necessary to identify, catalogue, register, and cross-reference a PP. The PP overview summarizes the profile in narrative form and provides sufficient information for a potential user to determine whether the PP is of interest. The overview can also be used as a standalone abstract for PP catalogues and registers. The conventions section provides an explanation of how this document is organized and the terms section gives a basic definition of terms that are specific to this PP. 1.1 PP Identification Title: NNSA Protection Profile for Open Public Unrestricted Access (OPENPP) Keywords: access control, discretionary access control, general-purpose operating system, information protection 1.2 PP Overview Environments, systems, and products conforming to the OPENPP support access controls that are capable of enforcing access limitations on individual users and data objects. OPENPP compliant systems also provide an audit capability that records the security-relevant events that occur within the system. The OPENPP provides for a level of protection that is appropriate for a well-managed user community requiring protection against threats of inadvertent or casual attempts to breach the system security. The profile is not intended to be applicable to circumstances in which protection is required against determined attempts by hostile and well-funded attackers to breach system security. The OPENPP does not fully address the threats posed by malicious system development or administrative personnel. These threats must be mitigated by other technical and non-technical measures. The OPENPP is generally applicable to distributed systems but does not address the security requirements that arise specifically out of the need to distribute the resources within a network. 1 Open, Public, Unrestricted -- Information that requires no protection from disclosure, e.g. approved for public release. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 2 1.3 Strength of Environment The OPENPP is for a publicly accessible environment. The strength of environment is based on the NNSA Consequences of Loss minimums defined in the NNSA PCSP and the threats from the NNSA Cyber Risk Assessment.

The assurance requirements and the minimum strength of function were chosen to be consistent with that level of risk. The assurance level is an NNSA AL 1, Functional Assurance, and the minimum strength of function is SOF-basic. 1.4 Conventions This document is organized based on Annex B of Part 1 of the Common Criteria. For each component, an application note may appear. Application notes document guidance for how the requirement is expected to be applied. For additional guidance, the CC itself should be consulted. Following the application note is rationale for the inclusion of the component in the requirement set. 1.5 Terms This profile uses the following terms that are described in this section to aid in the application of the requirements: • User • Authenticated User • Administrator • Discretionary Access Control (DAC) Policy • Access • Authorization • Category A user is an individual who attempts to invoke a service offered by the Target of Evaluation (TOE). An authenticated user is a user who has been properly identified and authenticated. These users are considered to be legitimate users of the TOE. An administrator is an authenticated user who has been granted the authority to manage the TOE. These users are expected to use this authority only in the manner prescribed by the guidance given them. 2. TOE DESCRIPTION The OPENPP defines a set of security requirements to be levied on Targets of Evaluation (TOEs) containing the Open Public Unrestricted Access Information Group. These TOEs include information systems that are personal electronic devices, portable computers, and systems containing general-purpose operating systems, such as workstations, mainframes, or personal computers. These systems can be comprised of a single host or a set of cooperating hosts in a distributed system. Such systems permit one or more processors along with peripherals and OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 3 storage devices to be used by single or multiple users to perform a variety of functions requiring access to the information stored on the system. The OPENPP is also generally applicable to TOEs incorporating network functions but contains no network specific requirements. Networking is covered only to the extent to which the TOE can be considered to be part of a centrally managed system that meets a common set of security requirements. The OPENPP assumes that responsibility for the safeguarding of the data protected by the TOEs security functions (TSF) can be delegated to the TOE users. All data is under the control of the TOE. The data are stored in objects and the TSF can associate a description of access rights with each controlled object. Most users are allowed access to the information that has been identified in the Open Public Unrestricted Access Information Group without requiring authentication. Activities of all users of the TOE are subject to monitoring. Users with roles and responsibilities to create or manage information on the system or perform system administration functions are assigned a unique identifier. This identifier supports individual accountability. The TSF authenticates the claimed identity of these users before allowing the user to perform any actions that require TSF mediation, other than actions that aid an authenticated user in gaining access to the TOE. 3. TOE SECURITY ENVIRONMENT 3.1 Assumptions

This section describes the security aspects of the environment in which the TOE will be, or is intended to be used. This includes information about the physical, personnel, and connectivity aspects of the environment. An OPENPP-conformant TOE is assured to provide effective security measures only if it is installed, managed, and used correctly. The operational environment must be managed in accordance with assurance requirements documentation for delivery, operation, and user/administrator guidance. The following specific conditions are assumed to exist in an environment where OPENPP-conformant TOEs are employed. 3.1.1 Physical Assumptions OPENPP-conformant TOEs are intended for application in user areas that have physical control and monitoring. It is assumed the following physical conditions will exist: A.LOCATE The TOE components will be located within controlled access facilities that will prevent unauthorized physical access. A.PROTECT The TOE hardware and software critical to security policy enforcement will be protected from unauthorized physical modification. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 4 3.1.2 Personnel Assumptions It is assumed the following personnel conditions will exist: A.MANAGE There will be one or more competent individuals assigned to manage the TOE and the security of the information it contains. A.TRAINED_ADM The system administrative personnel will follow and abide by the instructions provided by the administrator documentation. A.COOP Users possess the necessary authorization to access at least some of the information managed by the TOE and most users are expected to act in a benign manner. 3.1.3 Connectivity Assumptions The OPENPP contains no explicit network or distributed system requirements. However, it is assumed the following connectivity conditions exist: A.PEER Any other systems with which the TOE communicates are assumed to be under the same management control and operate under the same security policy constraints or that the TOE is isolated by appropriate barriers, such as controlled interfaces, firewalls, etc. PP-conformant TOEs are applicable to networked or distributed environments only if the entire network operates under the same constraints and resides within a single management domain. There are no security requirements that address connectivity to external systems or the communications links to such systems. A Controlled Interface may be necessary to preserve this assumption. A.CONNECT All connections to peripheral devices reside within the controlled access facilities. PP-conformant TOEs only address security concerns related to the manipulation of the TOE through its authorized access points. Internal communication paths to access points such as terminals are assumed to be adequately protected. 3.2 Threats These threats are addressed either by the TOE or the environment by OPENPP-compliant TOEs. The threat agents are either human users or external IT entities not authorized to use the TOE itself. The assets that are subject to attack are the information residing on the TOE and the TOE itself. 3.2.1 TOE Threats T.ABUSE_ADMIN System administrator abuse of privileges T.ABUSE_OTHER Compromise by authorized activities OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 5 T.ABUSE_USER Abuse of authorized user privileges T.ACCESS_MALICIOUS Unauthorized access by an authenticated user for malicious purposes T.ACCESS_UNDETECTED

P.ALT_INFRASTRUCT Information system users have, based on mission need, continuing access to the information system hardware and software assets. P.AUTH_MGMT The process of generating, issuing, and using authenticators is managed in accordance with NNSA and site policies. P.AUTHENTICATION All users shall be authenticated prior to being granted access to systems and the information and resources managed by those systems. P.COMPOSITION The security of an information system or network composed of individual information systems is equal to or greater than that of any individual system in the combined system. P.CONFIG_MGMT Protection features of a system are maintained during development, installation, modification, and maintenance of the hardware, firmware, and software components. P.CONOPS Continuity of operations planning is applied to mission essential applications, data, and information systems. P.CREDENTIAL_PROTECTION Authentication credentials shall be protected to prevent unauthorized access, modification or destruction. This policy requires that the individuals and IT entities that use the credentials adequately protect all credentials. The information system supports this policy by restricting access to credentials, by protecting the credentials as they are transmitted over the network during the domain authentication process, and through the trusted path between the credential reader and other information system components. P.CRYPTOGRAPHY Cryptographic services that are used to ensure information confidentiality, privacy or integrity shall meet the criteria of the appropriate robustness (strength of mechanism and assurance) based on the value (e.g., sensitivity or classified of the information to be protected and the threat environment. P.DATA_ASSURANCE Modification of data is permitted only by authorized personnel or processes. P.DATA_AVAILABILITY OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 10 User and information system data are available, or restorable, to meet mission availability requirements P.DENY_ACCESS System resources are controlled to ensure access to information sources cannot be denied to authorized users. P.DUE_CARE The information and information system resources are implemented and operated in a manner that represents due care and diligence with respect to risks to the information and the organization.

P.FILE_REVIEW An automated or administrative classification and sensitivity review is performed on all electronic communications and files that are to be electronically transmitted either beyond the system boundary or to an interconnected system that is not under the same management control and operating under the same security policy constraints before release. P.FORENSICS Information needed for penetration reconstruction, and analyzing on- going or past cyber attacks and failures is identified, collected, and preserved in accordance with NNSA and site policies. P.IDS The information system is protected from unauthorized attempts to attack or penetrate the information system. P.INFO_FLOW Information flow between information system components is controlled in accordance with established information flow policies. P.KNOWN All NNSA multi-user information systems, desktops, and laptops– excluding those information systems intended to provide public access (e. g., public web servers)– must have, and use, a mechanism that authenticates the identity of each person before providing access to any information system, application, service or resource. P.LEAST_PRIV Privileges granted to information system users (including privileged users) are the most restrictive (least privilege) set of privileges needed for the performance of authorized tasks. P.MALICIOUS_CODE The information system is protected from hardware, software, and firmware designed to adversely impact the confidentiality, integrity, and availability of the system and information assets. P.MEDIA_MARKING All removable media components of the information system and output inside the system boundary are appropriately marked with the level and category of the highest information sensitivity of information that the system is accredited to operate; or marked in accordance with OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 11 a classification review or information sensitivity review by authorized personnel. P.MEDIA_REVIEW All media (paper, disks, zip drives, removable disk drives, etc.) are reviewed for classification and sensitivity and properly marked before release outside the system boundary. P.MONITORING All user activities, and activities on behalf of the user, are monitored and reviewed for activities that are detrimental to the confidentiality, integrity or availability of the information or information system. P.NTK Access to data in information system resources is limited to users with the need-to-know for the information, regardless of the form of the information. Access rights to specific data objects are determined by object attributes assigned to that object, user identity, user attributes, and environmental conditions as defined by the security policy. P.PERSONNEL All users (including privileged users) are cleared, or have appropriate background reviews (whichever is appropriate), according to NNSA and DOE policies, for the highest level of information sensitivity, have formal access approval for, and an authorized need-to-know for, the information to which he/she is allowed access. P.PHYSICAL The information and information system resources (including media) are physically protected according to the sensitivity of the information processed, stored, or transmitted by the components. P.PROTCTD_DOMAIN

The information system security functions maintain a separate protected security domain for their own execution. The components necessary for enforcing the security policies of the information system security functions shall maintain a security domain for their own execution that protects them from interference and tampering by other system activities and users. P.RESIDUAL_DATA All internal information system resources are cleared before reallocation of the resource to a different user or environment. P.RISKASSESS Identification of system and environment vulnerabilities and an assessment of their impact on the system’s security are regularly performed. P.ROLE_SEPARATION Security roles and responsibilities are distributed to preclude any one individual from adversely affecting operations or the integrity of the system. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 12 P.SESSION_CTL User access to a system is determined by the authenticated user’s access profile. P.STRONG_AUTHENTICATION All users shall be authenticated by two- factor strong authentication mechanisms prior to being granted access to systems and the information and resources managed by those systems. P.SURVIVE The system in conjunction with its environment must be resilient to insecurity, resisting the insecurity and/ or providing the means to detect an insecurity and recover from it. P.SYS_ASSURANCE The information system’s security policy is maintained in the environment of distributed systems even if the systems are interconnected via an insecure networking medium (wire-lines, fiber, Internet, wireless, etc.). P.SYS_RECOVERY Controlled or trusted secure system recovery occurs in the event of an information system failure. P.SYS_TESTING Certification and post-accreditation testing is applied to the information system in accordance with PCSP and DAA requirements. P.TRAINING All users are trained to understand applicable system- use policies, the proper use of systems and the vulnerabilities inherent to those systems. This policy ensures that all users are properly instructed on policies and procedures for using the system, as well as, being able to acknowledge all threats and vulnerabilities that may impact system processing. P.TRUSTED_USER All users shall abide by designated policies and the conduct stated by those policies. In this context, ‘users’ includes both users of systems that interface with the TOE, and the administrators of systems that interface with the TOE in addition to the administrators of the TOE. This policy covers use and adherence to policies, procedures, system, admin, and user documentation, associated with the TOE and all systems that interface with the TOE. P.UNIQUE_ID Every authenticated user of an information system is uniquely identified. P.WARNING_BANNER All authorized users are notified that they are subject to being monitored, recorded, and audited through the use of an NNSA approved warning text and positive acknowledgement by the user is required before granting the user access to system resources. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 13 P.WFA Waste Fraud and Abuse is detected or prevented and reported in accordance with DOE O 221.1, Reporting Waste Fraud, and Abuse to the Office of IG. 4. SECURITY OBJECTIVES 4.1 Security Objectives for the TOE

O.ACCESS_HISTORY The information system user is notified upon successful logon of a) the date and time of the user’s last logon, b) the location of the user (as can best be determined) at last logon, and c) the number of unsuccessful logon attempts using this user ID since the last successful logon. A positive action by the user is required to remove the notice.

Procedures to detect and deter incidents caused by malicious code are employed. O.MANAGE_TOE The information system must provide all the functions and facilities necessary to support the administrators that are responsible for the management of information system security. O.NTK_NNSA Access rights to specific data objects are determined by object attributes assigned to that object, user identity, user attributes, and any formal access rights or privileges that NNSA has established for the data. O.RECOVERY_CONTROLLED Information system recovery is controlled via monitored terminal or system console. O.REPLAY The information system must detect and deter replay of entities, such as messages and service requests and responses. O.RESIDUAL_PROTECTION The information system must ensure that identified resources contain no residual data before being assigned, allocated, or reallocated. O.SEC_FUNC_MANAGEMENT The information system restricts management of information system security functions to authenticated users. O.SESSION_ESTABLISHMENT The information system controls the establishment of sessions (a) by denying access after multiple (maximum of five) consecutive unsuccessful attempts on the same user ID, (b) by limiting the number of access attempts in a specified time period, (c) by use of a time-delay control system, or (d) by other such methods, subject to approval by the DAA. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 16 O.TRUSTED_PATH The information system provides a trusted path between itself and the user for initial identification and authentication O.TSF_DOMAIN_SEPARATION The information system maintains a domain for its own execution that protects it from external interference and tampering (e. g., by reading or modifying its code and data structures). O.WARNING_BANNER All authorized users are notified that they are subject to being monitored, recorded, and audited through the use of an NNSA approved warning text and positive acknowledgement by the user is required before granting the user access to system resources. 4.2 Security Objectives for the Environment O.ACCESS Each user’s access rights and privileges are authorized, prior to the user's first access to the TOE. O.ACCESS_FORMAL Prior to their first access to information, each user’s need-to-know is formally authorized by management or the data owner-steward through a position description or written access list. O.ACCESS_MALICIOUS Environmental controls are required to sufficiently mitigate (deterrence, detection, and response) the threat of malicious actions by authenticated users. Information system controls will help in achieving this objective, but will not be sufficient. O.AUDIT_PROTECTION The contents of audit trails must be protected against unauthorized access, modification, or deletion. O.AUTHORIZE_NON_TOE The IT other than the information system must provide the ability to specify and manage user and system process access rights to individual processing resources and data elements under its control, supporting the organization’s security policy for access control.

OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 17 O.CREDENTIAL_PROTECTION Authentication credentials shall be protected like the information to which they provide access during creation, use, and handling. O.DATA_BACKUP_BASIC User and information system data are available, or restorable, to meet mission availability requirements. Periodic checking of backup inventory and testing of the ability to restore information is accomplished to validate mission availability requirements are met. O.DETECT_EXTERNAL_BASIC The site environment, i.e., on-line, must provide the ability to detect low level, i.e., using methods readily available on the Internet to attack known vulnerabilities, attacks on the hosts and networks from outside the site and the results of such attacks (e.g., corrupted system state), including measures to detect and respond to unauthorized attempts to penetrate or deny use. O.DETECT_NETWORK_BASIC The network environment, i.e., on-line, must provide the ability to detect low level, i.e., using methods readily available on the Internet to attack known vulnerabilities, attacks on the network and its components, and the results of such attacks (e.g., corrupted system state), including measures to detect and respond to unauthorized attempts to penetrate or deny use. O.DETECT_SITE_BASIC The site physical environment must provide the ability to detect low level, i.e., (using readily available methods to attack known vulnerabilities), attacks on the hosts and networks from inside the site and the results of such attacks (e.g., corrupted system state), including measures to detect and respond to unauthorized attempts to penetrate or deny use. O.ENTRY_NON_TECHNICAL The information system environment must provide sufficient protection against non-technical attacks by other than authenticated users. User training and awareness will provide a major part of achieving this objective. O.ENTRY_NON_TOE For resources not controlled by the information system, IT other than the information system must prevent logical entry using OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 18 unsophisticated, technical methods, by persons without authority for such access. O.FORENSICS_PROC Procedures are established and documented to ensure the identification, collection, and preservation of data needed to analyze penetration reconstruction, on-going cyber attacks and/ or failures O.HARDWARE_EXAM_MINIMUM Information system hardware components are examined for security impacts to the information system before use O.ID_DISABLE User TOE access is disabled when the user leaves the sponsoring organization, Access Authorization is terminated, loses authorized access (for cause, changes in organization, etc), or upon TOE detection of attempts to bypass security. O.ID_REMOVAL Prior to reuse of a user identifier, all previous access rights and privileges (including file accesses for that user identifier) are removed from the TOE O.ID_REVALIDATION User access, contact information, rights, and privileges, to include sponsor, Access Authorization, need-to-know, means for off line contact, mailing address, are validated annually.

O.INFO_FLOW The information system and information system environment must ensure that any information flow control policies are enforced - (1) between system components and (2) at the system external interfaces. O.NETWORK_INTERFACE The developers of the information system must ensure the information system security is not adversely affected by the characteristics of the network(s) to which the information system is interfaced. O.PHYSICAL Physical attack that might compromise IT security on those parts of the information system critical to security is deterred and detected, primarily via prevention within the limits of COTS technology. O.PHYSICAL_PROTECTION The individuals responsible for the information system must ensure that the environment is capable of physically protecting the information system by signaling the occurrence of fire, flood, power loss, and environmental control failures that might adversely affect information system operations. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 19 O.RECOVERY_CONTROLLED Information system recovery is controlled via monitored terminal or system console. O.REPLAY The information system must detect and deter replay of entities, such as messages and service requests and responses. O.SOFTWARE_EXAM_MINIMUM Information system software components are examined and tested for security impacts to the information system before use. O.TRAINING All users are trained to understand applicable information system-use policies, the approved use of the information system, the vulnerabilities inherent in the operation of the information system and their cyber security responsibilities.

IT SECURITY REQUIREMENTS An OPENPP-conformant TOE may include information systems that are personal electronic devices, portable computers, and systems containing general-purpose operating systems, such as workstations, mainframes, or personal computers. These systems can be comprised of a single host or a set of cooperating hosts in a distributed system. Such systems permit one or more processors along with peripherals and storage devices to be used by single or multiple users to perform a variety of functions requiring access to the information stored on the system. The security functional and assurance requirements defined in this section must be applied to all elements in the TOE. Some TOE components, where a single general user has the authority and responsibility to protect all general user data/information on the component (typically a single user desktop system) may be exempted from implementing these PP requirements with the approval of the cognizant Designated Approving Authority. Any TOE component where multiple general users may access data or share TOE resources must comply with the OPENPP requirements. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 20 5.1 TOE Security Functional Requirements

This section defines the functional requirements for the TOE. Functional requirements components in this profile were drawn from Part 2 of the CC. Some functional requirements are extensions to those found in the CC. CC defined operations for assignment, selection, and refinement were used to tailor the requirements to the level of detail necessary to meet the stated security objectives. These operations are indicated through the use of underlined (assignments and selections) and italicized (refinements) text. All required operations not performed within this profile are clearly identified and described such that they can be correctly performed upon instantiation of the PP into a Security Target (ST) specification. NOTE: Where italicized items are listed in an assignment or selection clause in one of the following components, the ST developer must address the component and provide the information identified in the italicized clause. If the assignment or selection clause is not italicized, the item is mandatory and must be addressed in the ST. 5.1.1 FAU_ARP.1 Security alarms 5.1.1.1 FAU_ARP.1.1 The TSF shall take [assignment: list of the least disruptive actions] upon detection of a potential security violation. Application Note: The ST must state the actions taken by the TOE when a potential security violation, such as detection of malicious code, or a successful or unsuccessful intrusion. 5.1.2 FAU_GEN.1 Audit data generation 5.1.2.1 FAU_GEN.1.1 The TSF shall be able to generate an audit record of the following auditable events: • Start-up and shutdown of the audit functions; • All auditable events for the basic level of audit; and • The events listed below: o Successful use of the user security attribute administration functions o All attempted uses of the user security attribute administration functions o Identification of which user security attributes have been modified o Successful and unsuccessful logons and logoffs o Unsuccessful access to security relevant files including creating, opening, closing, modifying, and deleting those files OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 21 o Changes in user authenticators o Blocking or blacklisting user Ids, terminals, or access ports o Denial of access for excessive logon attempts o System accesses by privileged users; a. Privileged activities at the system console (either physical or logical consoles) and other system- level accesses by privileged users. o Starting and ending times for each access to the system Application Note: For some situations it is possible that some events cannot be automatically generated. This is usually due to the audit functions not being operational at the time these events occur. Such events need to be documented in administrative guidance, along with recommendations on how manual auditing will be established to cover these events. 5.1.2.2 FAU_GEN.1.2 The TSF shall record within each audit record at least the following information: a. Date and time of the event, type of event, subject identity, and the outcome (success or failure) of the event; and b. For each audit event type, based on the auditable event definitions of the functional components included in the PP/ST, [assignment: other audit relevant information] 5.1.3 FAU_GEN.2 User identity association 5.1.3.1 FAU_GEN.2.1 The TSF shall be able to associate each auditable event with the identity of the user that caused the event.

Application Note: There are some auditable events that may not be associated with a user, such as failed login attempts. It is acceptable that such events do not include a user identity. In the case of failed login attempts it is also acceptable not to record the attempted identity in cases where that attempted identity could be misdirected authentication data; for example when the user may have been out of sync and typed a password in place of a user identifier. 5.1.4 FAU_SAA.4 Complex attack heuristics 5.1.4.1 FAU_SAA.4.1 The TSF shall be able to maintain an internal representation of the following event sequences of known intrusion scenarios [assignment: list of sequences of system events whose occurrence are representative of known penetration scenarios] and the following signature events [assignment: a subset of system events] that may indicate a potential violation of the TSP. Application Note: The ST must describe, or reference documentation of, known or suspected system events and penetration scenarios that may indicate a potential security OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 22 violation. The specific manner of implementation is TOE dependent and can be achieved through the use of intrusion detection software on the TOE or in the local area network where the TOE is located. 5.1.4.2 FAU_SAA.4.2 The TSF shall be able to compare the signature events and event sequences against the record of system activity discernible from an examination of [assignment: the information to be used to determine system activity]. Application Note: See application note for FAU_SAA.4.1. 5.1.4.3 FAU_SAA.4.3 The TSF shall be able to indicate an imminent violation of the TSP when system activity is found to match a signature event or event sequence that indicates a potential violation of the TSP. Application Note: See application note for FAU_SAA.4.1. 5.1.5 FAU_SAR.1 Audit review 5.1.5.1 FAU_SAR.1.1 The TSF shall provide [assignment: Computer System Security Officers (CSSO) and authorized system administrators] with the capability to read [assignment: all audit information] from the audit records. Application Note: The minimum information that must be provided is the same as that which is required to be recorded in FAU_GEN.1.2. The intent of this requirement is that there exists a tool for an administrator to access the audit trail in order to assess it. Exactly what manner is provided is an implementation decision, but it needs to be done in a way that allows the administrator to make effective use of the information presented. 5.1.5.2 FAU_SAR.1.2 The TSF shall provide the audit records in a manner suitable for the user to interpret the information. 5.1.6 FAU_SAR.2 Restricted audit review 5.1.6.1 FAU_SAR.2.1 The TSF shall prohibit all users read access to the audit records, except those users that have been granted explicit read-access. Application Note: By default, CSSOs must be granted read access and authorized system administrators may be considered to have been granted read access to the audit records. The TSF may provide a mechanism that allows other users to also read audit records. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 23 5.1.7 FAU_SEL.1 Selective Audit 5.1.7.1 FAU_SEL.1.1 The TSF shall be able to include or exclude auditable events from the set of audited events based on the following attributes: a. User identity;

b. [assignment: list of additional attributes that audit selectivity is based upon]. Application Note: The ST must state the additional attributes that audit selectivity may be based upon (e. g., object identity, type of event), if any. 5.1.8 FAU_STG.2 Guarantees of audit data availability 5.1.8.1 FAU_STG.2.1 The TSF shall protect the stored audit records from unauthorized deletion. 5.1.8.2 FAU_STG.2.2 The TSF shall be able to [selection: prevent] modifications to the audit records. Application Note: On many systems, in order to reduce the performance impact of audit generation, audit records will be temporarily buffered in memory before they are written to disk. In these cases, it is likely that some of these records will be lost if the operation of the TOE is interrupted by hardware or power failures. The developer needs to document what the likely loss will be and show that it has been minimized. 5.1.8.3 FAU_STG.2.3 The TSF shall ensure that [assignment: all audit records already written to media, i.e., not in memory buffers,] audit records will be maintained when the following conditions occur: [selection: audit storage exhaustion, failure, and attack]. 5.1.9 FDP_ACC.2 Complete access control 5.1.9.1 FDP_ACC.2.1 The TSF shall enforce the [assignment: Discretionary Access Control Policy (DAC)] on [assignment: list of subjects] acting on the behalf of users, [assignment: list of named objects] and all operations among subjects and objects covered by the SFP [DAC policy]. Application Note: For most systems there is only one type of subject, usually called a process or task, which needs to be specified in the ST. Also, for information systems conforming to this PP, all public unauthenticated users accessing the system can be viewed as a general class of user in the Discretionary Access Control policy. These users are expected to have very limited rights to access objects on the system. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 24 Named objects are those objects which are used to share information among subjects acting on the behalf of different users, and for which access to the object can be specified by a name or other identity. Any object that meets this criterion but is not controlled by the DAC policy must be justified. The list of operations covers all operations between the above two lists. It may consist of a sublist for each subject-named object pair. Each operation needs to specify which type of access right is needed to perform the operation; for example read access or write access. 5.1.9.2 FDP_ACC.2.2 The TSF shall ensure that all operations between any subject in the TSF Scope of Control (TSC) and any object within the TSC are covered by an access control SFP. 5.1.10 FDP_ACF.1 Security attribute based access control 5.1.10.1 FDP_ACF.1.1 The TSF shall enforce the [assignment: Discretionary Access Control Policy] to objects based on [assignment: the following:] a. The user identity and group membership(s) associated with a subject; b. The following access control attributes associated with an object; and c. [assignment: List access control attributes. The attributes must provide permission attributes with: 1. the ability to associate allowed or denied operations with one or more user identities; 2. the ability to associate allowed or denied operations with one or more group identities; and 3. defaults for allowed or denied operations.

5.1.10.2 FDP_ACF.1.2 The TSF shall enforce the following rules to determine if an operation among controlled subjects and controlled objects is allowed: [assignment: a set of rules specifying the Discretionary Access Control policy, where: a. For each operation there shall be a rule, or rules, that use the permission attributes where the user identity of the subject matches a user identity specified in the access control attributes of the object; b. For each operation there shall be a rule, or rules, that use the permission attributes where the group membership of the OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 25 subject matches a group identity specified in the access control attributes of the object; and c. For each operation there shall be a rule, or rules, which use the default permission attributes specified in the access control attributes of the object when neither a user identity nor group identity matches.] Application Note: A TOE that conforms to this PP is required to implement a DAC policy, but the rules that govern the policy may vary between TOEs; those rules need to be specified in the ST. In completing the rule assignment above, the resulting mechanism must be able to specify access rules that apply to at least any single user. This single user may have a special status such as the owner of the object. The mechanism must also support specifying access to the membership of at least any single group. Conformant implementations include self/ group/ public controls and access control lists. A DAC policy may cover rules on accessing public objects; i.e., objects which are readable to all authorized users, but which can only be altered by the TSF or administrators. Specification of these rules should be covered under FDP_ACF.1.3 and FDP_ACF.1.4. A DAC policy may include exceptions to the basic policy for access by administrators or other forms of special authorization. These rules should be covered under FDP_ACF.1.3. The ST must list the attributes that are used by the DAC policy for access decisions. These attributes may include permission bits, access control lists, and object ownership. A single set of access control attributes may be associated with multiple objects, such as all objects stored on a single floppy disk. The association may also be indirectly bound to the object, such as access control attributes being associated with the name of the object rather than directly to the object itself. 5.1.10.3 FDP_ACF.1.3 The TSF shall explicitly authorize access of subjects to objects based on the following additional rules: [assignment: rules, based on security attributes, that explicitly authorize access of subjects to objects]. 5.1.10.4 FDP_ACF.1.4 The TSF shall explicitly deny access of subjects to objects based on the [assignment: rules, based on security attributes, that explicitly deny access of subjects to objects]. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 26 5.1.11 FDP_RIP.1 Subset residual information protection 5.1.11.1 FDP_RIP.1.1 The TSF shall ensure that any previous information content of a resource is made unavailable upon the [selection: allocation of the resource] to the following objects: [assignment: list of objects]. Application Note: This requirement applies to the list of resources stated in the ST; it includes resources used to contain data and attributes. It also includes the encrypted representation of information.

Clearing the information content store of resources on deallocation from objects is sufficient to satisfy this requirement, if unallocated resources will not accumulate new information until they are allocated again. 5.1.12 FDP_SDI.2 Stored data integrity monitoring and action 5.1.12.1 FDP_SDI.2.1 The TSF shall monitor user data stored within the TSC for [assignment: unauthorized modification and unauthorized deletion] on all objects, based on the following attributes: [assignment: user data attributes]. Application Note: The ST must describe the user data attributes, i.e. file names, directory names, sizes, etc., that will be used in the detection of unauthorized activities on the data. 5.1.12.2 FDP_SDI.2.2 Upon detection of a data integrity error, the TSF shall [assignment: enter a description of the error in the audit log and issue an alarm]. Application Note: For this component, an "alarm" is to be interpreted as any clear indication to the administrator that a data integrity error has been detected. The ST must state the conditions that trigger generation of the alarm. 5.1.13 FIA_AFL.1 Authentication failure handling 5.1.13.1 FIA_AFL.1.1 The TSF shall detect when [assignment: five (5) consecutive] unsuccessful authentication attempts occur related to [assignment: list of authentication events]. Application Note: The ST must state the authentication events that will be monitored for 5 consecutive unsuccessful authentication attempts. The ST should also identify any authentication activities that are not monitored for unsuccessful authentication attempts. This component does not apply to public users who are granted public, unauthenticated access to the information system. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 27 5.1.13.2 FIA_AFL.1.2 When the defined number of unsuccessful authentication attempts has been met or surpassed, the TSF shall [assignment: list of actions]. 5.1.14 FIA_ATD.1 User attribute definition 5.1.14.1 FIA_ATD.1.1 The TSF shall maintain the following list of security attributes belonging to individual users: [assignment: a. User Identifier; b. Group Memberships; c. Authentication Data; d. Security-relevant Roles; and e. [assignment: other user security attributes]]. Application Note: The specified attributes are those that are required by the TSF to enforce the DAC policy, the generation of audit records, and proper identification and authentication of users. The user identity must be uniquely associated with a single individual user. Group membership may be expressed in a number of ways: a list per user specifying to which groups the user belongs, a list per group which includes which users are members, or implicit association between certain user identities and certain groups. A TOE may have two forms of user and group identities, a text form and a numeric form. In these cases there must be unique mapping between the representations. 5.1.15 FIA_SOS.1 Verification of secrets 5.1.15.1 FIA_ SOS. 1.1 The TSF shall provide a mechanism to verify that secrets meet [assignment: the P.STRONG_AUTHENTICATION policy]. Application Note: The P.STRONG_.AUTHENTICATION policy and this component do not apply to public users who are granted public unauthenticated access to the information system.

The P.STRONG_AUTHENTICATION policy applies to all other information system users. The method of authentication is unspecified by this PP, but must be specified in the ST. The method that is used must be shown to implement the P.STRONG_AUTHENTICATION policy. If a password mechanism is used, the mechanism must comply with NNSA password policies. The strength of whatever mechanism implemented must be subjected to strength of function analysis. (See AVA_SOF.1) OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 28 5.1.16 FIA_UAU.1 Timing of authentication 5.1.16.1 FIA_UAU.1.1 The TSF shall allow [assignment: list of TSF mediated actions] on behalf of the user to be performed before the user is authenticated. Application Note: This component does not apply to public users who are granted public unauthenticated access to the information system. 5.1.16.2 FIA_UAU.1.2 The TSF shall require each user to be successfully authenticated before allowing any other TSF-mediated actions on the behalf of that user. Application Note: This component does not apply to public users who are granted public unauthenticated access to the information system. The ST must specify the actions that are allowed by an unauthenticated user. The allowed actions should be limited to those things that aid an authenticated user in gaining access to the TOE. This could include help facilities or the ability to send a message to administrators. 5.1.17 FIA_UAU.7 Protected authentication feedback 5.1.17.1 FIA_UAU.7.1 The TSF shall provide only [assignment: obscured feedback] to the user while the authentication is in progress. Application Note: This component does not apply to public users who are granted public unauthenticated access to the information system. Obscured feedback implies the TSF does not produce a visible display of any authentication data entered by a user, such as through a keyboard (e. g., echo the password on the terminal). It is acceptable that some indication of progress be returned instead, such as a period returned for each character sent. Some forms of input, such as card input based batch jobs, may contain human-readable user passwords. The administrative and user guidance documentation must explain the risks in placing passwords on such input and must suggest procedures to mitigate that risk. 5.1.18 FIA_UID.1 Timing of identification 5.1.18.1 FIA_UID.1.1 The TSF shall allow [assignment: list of TSF-mediated actions] on behalf of the user to be performed before the user is identified. 5.1.18.2 FIA_UID.1.2 The TSF shall require each user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 29 Application Note: The ST must specify the actions that are allowed to an unidentified user. The allowed actions should be limited to those things that aid an authenticated user in gaining access to the TOE. This could include help facilities or the ability to send messages to administrators. The method of identification is unspecified by this PP, but should be specified in a ST and it should specify how this relates to user identifiers maintained by the TSF. 5.1.19 FIA_USB.1 User-subject binding 5.1.19.1 FIA_USB.1.1 The TSF shall associate the following user security attributes with subjects acting on behalf of that user: a. The user identity which is associated with auditable events;

b. The user identity or identities which are used to enforce the Discretionary Access Control Policy; c. The group membership or memberships used to enforce the Discretionary Access Control Policy; d. [assignment: any other user security attributes]. 5.1.20 FIA_USB.1 User-subject binding 5.1.20.1 FIA_USB.1.1 The TSF shall enforce the following rules governing changes to the user security attributes associated with subjects acting on the behalf of a user: [assignment: changing of attributes rules]. Application Note: The DAC policy and audit generation require that each subject acting on the behalf of users have a user identity associated with the subject. This identity is normally the one used at the time of identification to the system. The DAC policy enforced by the TSF may include provisions for making access decisions based on a user identity which differs from the one used during identification. The ST must state, in FIA_USB.1.1, how this alternate identity is associated with a subject and justify why the individual user associated with this alternate identity is not compromised by the mechanism used to implement it. Depending on the TSF implementation of group membership, the associations between a subject and groups may be explicit at the time of identification or implicit in a relationship between user and group identifiers. The ST must specify this association. Like user identification, an alternate group mechanism may exist, and parallel requirements apply. 5.1.21 FMT_MOF.1 Management of security functions behavior 5.1.21.1 FMT_MOF.1.1 The TSF shall restrict the ability to [selection: determine the behavior of, disable, enable, modify the behavior of] the functions OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 30 [assignment: list of functions] to [assignment: CSSOs and authorized system administrators]. Application Note: The ST must state the restrictions and functions applied to the management of TOE security functions by the CSSO and authorized system administrators. 5.1.22 FMT_MSA.1 Management of security attributes 5.1.22.1 FMT_MSA.1.1 The TSF shall enforce the [assignment: Discretionary Access Control Policy] to restrict the ability to [selection: modify] the security attributes [assignment: access control attributes associated with a named object] to [assignment: the authorized users]. Application Note: The ST must state the components of the access rights that may be modified, and must state any restrictions that may exist for a type of authorized user and the components of the access rights that the user is allowed to modify. The ability to modify access rights must be restricted in that a user having access rights to a named object does not have the ability to modify those access rights unless explicitly granted the right to do so. This restriction may be explicit, based on the object ownership, or based on a set of object hierarchy rules. 5.1.23 FMT_MSA.3 Static attribute initialization 5.1.23.1 FMT_MSA.3.1 The TSF shall enforce the [assignment: Discretionary Access Control Policy] to provide [selection: restrictive] default values for security attributes that are used to enforce the SFP [Discretionary Access Control Policy]. 5.1.23.2 FMT_MSA.3.2 The TSF shall allow the [assignment: the authorized identified roles] to specify alternative initial values to override the default values when an object or information is created.

Application Note: A TOE conforming to this PP must provide protection by default for all objects at creation time. This may be done through the enforcing of a restrictive default access control on newly created objects or by requiring the user to explicitly specify the desired access controls on the object at its creation. In either case, there shall be no obvious window of vulnerability through which unauthorized access may be gained to newly created objects. 5.1.24 FMT_MTD.1 Management of TSF data 5.1.24.1 FMT_MTD.1.1 The TSF shall restrict the ability to [selection: create, delete, and clear] the [assignment: audit trail] to [assignment: CSSOs and authorized system administrators]. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 31 Application Note: The selection of "create, delete, and clear" functions for audit trail management reflect common management functions. These functions should be considered generic; any other audit administration functions that are critical to the management of a particular audit mechanism implementation should be specified in the ST. 5.1.25 FMT_MTD.1 Management of TSF data 5.1.25.1 FMT_MTD.1.1The TSF shall restrict the ability to modify or observe the set of audited events to CSSOs and administrators. Application Note: The set of audited events are the subset of auditable events that will be audited by the TSF. The term “set” is used loosely here and refers to the total collection of possible ways to control which audit records get generated; this could be by type of record, identity of user, identity of object, etc. It is an important aspect of audit that users are able to affect which of their actions are audited, and therefore must not have control over or knowledge of the selection of an event for auditing. 5.1.26 FMT_MTD.1 Management of TSF data FMT_MTD.1.1 The TSF shall restrict the ability to initialize and modify the user security attributes, other than authentication data, to administrators. Application Note: This component only applies to security attributes that are used to maintain the TSP. Other user attributes may be specified in the ST, but control of those attributes is not within the scope of this PP. 5.1.27 FMT_MTD.1 Management of TSF data 5.1.27.1 FMT_MTD.1.1 The TSF shall restrict the ability to modify the authentication data to the following: a) CSSOs and administrators; and b) users authorized to modify their own authentication data Application Note: User authentication data refers to information that users must provide to authenticate them to the TSF. Examples include passwords, personal identification numbers, and fingerprint profiles. User authentication data does not include the user's identity. The ST must specify the authentication mechanism that makes use of the user authentication data to verify a user's identity. This component does not require that any user be authorized to modify their authentication information; it only states that it is permissible. It is not necessary that requests to modify authentication data require re-authentication of the requester's identity at the time of the request. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 32 5.1.28 FMT_REV.1 Revocation 5.1.28.1 FMT_REV.1.1 The TSF shall restrict the ability to revoke security attributes associated with the [selection: users] within the TSC to [assignment: the CSSO and authorized system administrators]. 5.1.28.2 FMT_REV.1.2 The TSF shall enforce the rules: [assignment:

a) The immediate revocation of security-relevant authorizations; and b) [assignment: list of other revocation rules concerning users]]. 5.1.29 FMT_REV.1 Revocation 5.1.29.1 FMT_REV.1.1 The TSF shall restrict the ability to revoke security attributes associated with objects within the TSC to users authorized to modify the security attributes by the Discretionary Access Control policy. Application Note: Many security-relevant authorizations could have serious consequences if misused, so an immediate revocation method must exist, although it need not be the usual method (e. g., The usual method may be editing the trusted users profile, but the change doesn't take effect until the user logs off and logs back on. The method for immediate revocation might be to edit the trusted users profile and "force" the trusted user to log off.). The immediate method must be specified in the ST and in administrator guidance. In a distributed environment the developer must provide a description of how the "immediate" aspect of this requirement is met. 5.1.29.2 FMT_REV.1.2 The TSF shall enforce the rules: [assignment: a) The access rights associated with an object shall be enforced when an access check is made; and b) [assignment: list of other revocation rules concerning objects]]. Application Note: The DAC policy may include immediate revocation (e. g., Multics immediately revokes access to segments) or delayed revocation (e. g., most UNIX systems do not revoke access to already opened files). The DAC access rights are considered to have been revoked when all subsequent access control decisions by the TSF use the new access control information. It is not required that every operation on an object make an explicit access control decision as long as a previous access control decision was made to permit that operation. It is sufficient that the developer clearly documents in guidance documentation how revocation is enforced. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 33 5.1.30 FMT_SMR.2 Restrictions on security roles 5.1.30.1 FMT_SMR.2.1 The TSF shall maintain the roles: [assignment: a) CSSO; b) administrator; c) users authorized by the Discretionary Access Control Policy to modify object security attributes; d) users authorized to modify their own authentication data; and e) [assignment: other roles]]. Application Note: The ST must identify any other security relevant roles supported by the TOE. 5.1.30.2 FMT_SMR.2.2 The TSF shall be able to associate users with roles. Application Note: A TOE conforming to this PP only needs to support a single administrative role, referred to as the administrator. If a TOE implements multiple independent roles, the ST should refine the use of the term administrators to specify which roles fulfill which requirements. This PP specifies a number of functions that are required of or restricted to an administrator, but there may be additional functions that are specific to the TOE. This would include any additional function that would undermine the proper operation of the TSF. Examples of functions include: ability to access certain system resources like tape drives or vector processors, ability to manipulate the printer queues, and ability to run real-time programs. 5.1.30.3 FMT_SMR.2.3 The TSF shall ensure that the conditions [assignment: conditions for the different roles] are satisfied.

Application Note: If conditions or restrictions are applied to the different security relevant roles supported by the TOE, the conditions or restrictions must be stated in the ST. 5.1.31 FPT_AMT.1 Abstract machine testing 5.1.31.1 FPT_AMT.1.1 The TSF shall run a suite of tests [selection: during initial start-up, periodically during normal operation, at the request of an authorized user, other conditions] to demonstrate the correct operation of the security assumptions provided by the abstract machine that underlies the TSF. Application Note: In general this component refers to the proper operation of the hardware platform on which a TOE is running. The test suite needs to cover only OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 34 aspects of the hardware on which the TSF relies to implement required functions, including domain separation. If a failure of some aspect of the hardware would not result in the TSF compromising the functions it performs, then testing of that aspect is not required. 5.1.32 FPT_RCV.1 Manual recovery 5.1.32.1 FPT_RCV.1.1 After a failure or service discontinuity, the TSF shall enter a maintenance mode where the ability to return the TOE to a secure state is provided. 5.1.33 FPT_RVM.1 Reference Mediation 5.1.33.1 FPT_RVM.1.1 The TSF shall ensure that the TSP enforcement functions are invoked and succeed before each function within the TSC is allowed to proceed. Application Note: This element does not imply that there must be a reference monitor. Rather this requires that the TSF validate all actions between subjects and objects that require policy enforcement. 5.1.34 FPT_SEP.2 SFP domain separation 5.1.34.1 FPT_SEP.2.1 The unisolated portion of the TSF shall maintain a security domain for its own execution that protects it from interference and tampering by untrusted subjects. 5.1.34.2 FPT_SEP.2.2 The TSF shall enforce separation between the security domains of subjects in the TSC. Application Note: This component does not imply a particular implementation of a TOE. The implementation needs to exhibit properties that the code and the data upon which TSF relies are not alterable in ways that would compromise the TSF and that observation of TSF data would not result in failure of the TSF to perform its job. This could be done either by hardware mechanisms or hardware architecture. Possible implementations include multi-state CPU’s that support multiple task spaces and independent nodes within a distributed architecture. The second element can also be met in a variety of ways also, including CPU support for separate address spaces, separate hardware components, or entirely in software. The latter is likely in layered application such as a graphic user interface system that maintains separate subjects. 5.1.34.3 FPT_SEP.2.3 The TSF shall maintain the part of the TSF related to [assignment: Discretionary Access Control policy] in a security domain for their own execution that protects them from interference and tampering by the remainder of the TSF and by subjects untrusted with respect to those SFPs. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 35 5.1.35 FPT_STM.1 Reliable time stamps 5.1.35.1 FPT_STM.1.1 The TSF shall be able to provide reliable time stamps for its own use. Application Note: The generation of audit records depends on having a correct date and time. The ST needs to specify the degree of accuracy that must be maintained in order to maintain useful information for audit records.

5.1.36 FPT_TST.1 TSF testing 5.1.36.1 FPT_TST.1.1 The TSF shall run a suite of self-tests [selection: during initial start-up, periodically during normal operation, at the request of the authorized user, at the conditions [assignment: conditions under which self test should occur]] to demonstrate the correct operation of the TSF. Application Note: In general this component refers to the proper operation of the TSF. The test suite needs to cover only aspects of the required functions of the TSF, including domain separation. 5.1.36.2 FPT_TST.1.2 The TSF shall provide authorized users with the capability to verify the integrity of TSF data. 5.1.36.3 FPT_TST.1.3 The TSF shall provide authorized users with the capability to verify the integrity of stored TSF executable code. 5.1.37 FTA_MCS.1 Basic limitation on multiple concurrent sessions 5.1.37.1 FTA_MCS.1.1 The TSF shall restrict the maximum number of concurrent sessions that belong to the same user. 5.1.37.2 FTA_MCS.1.2 The TSF shall enforce, by default, a limit of [assignment: one (1)] session per user. 5.1.38 FTA_SSL.2 User-initiated locking 5.1.38.1 FTA_SSL.2.1 The TSF shall allow user-initiated locking of the user’s own interactive session, by: a. Clearing or overwriting display devices, making the current contents unreadable; b. Disabling any activity of the user’s data access/display devices other than unlocking the session. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 36 5.1.38.2 FTA_SSL.2.2 The TSF shall require the following events to occur prior to unlocking the session: [assignment: events to occur]. Application Note: The ST must identify the events, if any, such as user authentication, necessary to unlock a session. 5.1.39 FTA_TAB TOE Access Banners 5.1.39.1 FTA_TAB.1.1 Before establishing a user session, the TSF shall display an advisory warning message regarding unauthorized use of the TOE. Application Note: The warning banner must comply with the NNSA PCSP minimum banner or use an alternative banner wording approved by the organization’s general counsel. 5.1.40 FTA_TAH.1 TOE access history 5.1.40.1 FTA_TAH.1.1 Upon successful session establishment, the TSF shall display the [selection: date, time, method, and location] of the last successful session establishment to the user. 5.1.40.2 FTA_TAH.1.2 Upon successful session establishment, the TSF shall display the [selection: date, time, method, location] of the last unsuccessful attempt to session establishment and the number of unsuccessful attempts since the last successful session establishment. 5.1.40.3 FTA_TAH.1.3 The TSF shall not erase the access history information from the user interface without giving the user an opportunity to review the information. 5.1.41 FTA_TSE.1 TOE session establishment 5.1.41.1 FTA_TSE.1.1 The TS F shall be able to deny session establishment based on [assignment: attributes]. 5.1.42 FTP_TRP.1 Trusted Path 5.1.42.1 FTP_TRP.1.1 The TSF shall provide a communication path between itself and [selection: local] users that is logically distinct from other communication paths and provides assured identification of its end points and protection of the communicated data from modification or disclosure. 5.1.42.2 FTP_TRP.1.2 The TSF shall permit [selection: the TSF, local users, remote users] to initiate communication via the trusted path. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 37

5.1.42.3 FTP_TRP.1.3 The TSF shall require the use of the trusted path for initial user authentication, [assignment: other services for which trusted path is required]]. 5.2 TOE Security Assurance Requirements 5.2.1 Configuration Management 5.2.1.1 ACM_CAP.1 Version Numbers 5.2.1.1.1 Developer action elements ACM_CAP1.1D The developer shall provide a reference for the TOE. 5.2.1.1.2 Content and presentation of evidence elements ACM_CAP1.1C The reference for the TOE shall be unique to each version of the TOE ACM_CAP1.2C The TOE shall be labeled with its reference 5.2.1.1.3 Evaluator action elements ACM_CAP1.1E The Evaluator shall confirm that the information provided meets all the requirements for the content and presentation of evidence. 5.2.2 Delivery and Operation 5.2.2.1 ADO_IGS.1 Installation, generation, and startup procedures 5.2.2.1.1 Developer action elements ADO_IGS.1.1D The developer shall document procedures necessary for the secure installation, generation, and startup of the TOE. 5.2.2.1.2 Content and presentation of evidence elements ADO_IGS.1.1C The documentation shall describe the steps necessary for secure installation, generation, and start-up of the TOE. 5.2.2.1.3 Evaluator action elements ADO_IGS.1.1E The evaluator shall confirm that the information provided meets all requirements for content and presentation of evidence. ADO_IGS.1.2E The evaluator shall determine that the installation, generation and startup procedures result in a secure configuration. OPEN UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.0 38 Application Note: The required documentation depends on the way that the TOE is generated and installed. For example the generation of the TOE from source code may be done at the development site, in which case the required documentation would be considered part of the design documentation. On the other hand, if some part of the TOE generation is done by the TOE administrator, it would be part of the administrative guidance. Similar circumstances would apply to both installation and startup procedures. 5.2.3 Development 5.2.3.1 ADV_FSP.1 Informal functional specification 5.2.3.1.1 Developer action elements ADV_FSP.1.1D The developer shall provide a functional specification. 5.2.3.1.2 Content and presentation of evidence elements ADV_FSP.1.1C The functional specification shall describe the TSF and its external interfaces using an informal style. ADV_FSP.1.2C The functional specification shall be internally consistent. ADV_FSP.1.3C The functional specification shall describe the purpose and method of use of all external TSF interfaces, providing details of effects, exceptions, and error messages as appropriate. ADV_FSP.1.4C The functional specification shall completely represent the TSF. 5.2.3.1.3 Evaluator Action elements ADV_FSP.1.1E The evaluator shall confirm that the information provided meets all the requirements for content and presentation of evidence. ADV_FSP.1.2E The evaluator shall determine that the functional specification is an accurate and complete representation of the TOE security functional requirements. Application Note: This component requires that the design documentation include a complete external description of the TSF. In particular it needs to address the mechanisms that are used to meet the functional requirements of the PP. Other areas need to be addressed to the degree that they affect the functional requirements.

5.2.3.2 ADV_RCR.1 Informal Correspondence Demonstration OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 39 5.2.3.2.1 Developer action elements ADV_RCR.1.1D The developer shall provide an analysis of the correspondence between all adjacent pairs of the TSF representations that are provided. 5.2.3.2.2 Content and presentation of evidence elements ADV_RCR.1.1C For each adjacent pair of the provided TSF representations the analysis shall demonstrate that all relevant security functionality of the more abstract TSF representation is correctly and completely refined in the less abstract representation. 5.2.3.2.3 Evaluator action elements ADV_RCR.1.1E The evaluator shall confirm that the information provided meets all requirements for the content and presentation of evidence. 5.2.4 Guidance Documents 5.2.4.1 AGD_ADM.1 Administrator Guidance 5.2.4.1.1 Developer action elements AGD_ADM.1.1D The developer shall provide administrator guidance addressed to system administrative personnel. 5.2.4.1.2 Content and presentation of evidence elements AGD_ADM.1.1C The administrator guidance shall describe the administrative functions and interfaces available to the administrator of the TOE.

Application Note: The content required by this component is quite comprehensive and broadly stated: in particular the content needs to address any of the mechanisms and functions provided to the administrator to meet the functional requirements of the PP. It should also contain warnings about actions that may typically be done by administrators that should not be done on this specific TOE. This may include activating certain features or installing certain software that would compromise the TSF. 5.2.4.2 AGD_USR.1 User Guidance 5.2.4.2.1 Developer action elements AGD_USR.1.1D The developer shall provide user guidance 5.2.4.2.2 Content and presentation of evidence elements AGD_USR.1.1C The user guidance shall describe the functions and interfaces available to the non-administrative users of the TOE.

Note: this includes the securing of media, passwords, and etc. AGD_USR.1.5C The user guidance shall be consistent with all other documentation supplied for evaluation. AGD_USR.1.6C The user guidance shall describe all security requirements for the IT environment that are relevant to the user. OPEN PUBLIC UNRESTRICTED ACCESS PROTECTION PROFILE VERSION 1.2 41 5.2.4.2.3 Evaluator action elements AGD_USR.1.1E The evaluator shall confirm that the information provided meets all requirements for the content and presentation of evidence. Application Note: The content required by this component is quite comprehensive and broadly stated: in particular the content needs to address any of the mechanisms and functions provided to the user to meet the functional requirements of the PP. It should also contain warnings about actions that may typically be done by users that should not be done on this specific TOE. 5.2.5 Life Cycle Support 5.2.5.1 ALC_FLR.1 Basic Flaw Remediation 5.2.5.1.1 Developer action elements ALC_FLR.1.1D The developer shall document the flaw remediation procedures. 5.2.5.1.2 Content and presentation of evidence elements ALC_FLR.1.1C The flaw remediation procedures documentation shall describe the procedures used to track all reported security flaws in each release of the TOE. ALC_FLR.1.2C the flaw remediation procedures shall require that a description of the nature and effect of each security flaw be provided as well as the status of finding a correction to the flaw. ALC_FLR.1.3C The flaw remediation procedures shall require that corrective actions be identified for each of the security flaws. ALC_FLR.1.4C The flaw remediation procedures documentation shall describe the methods used to provide flaw information, corrections, and guidance on corrective actions to TOE users. 5.2.5.1.3 Evaluator action elements ALC_FLR.1.1E The evaluator shall confirm that the information provided meets all requirements for the content and presentation of evidence. 5.2.5.1.4 ATE_IND.1 Independent testing – conformance 5.2.5.1.5 Developer action elements ATE_IND.1.1D The developer shall provide the TOE for testing. 5.2.5.1.6 Content and presentation of evidence elements ATE_IND.1.1C The TOE shall be suitable for testing.

ATE_IND.1.2E The evaluator shall test a subset of the TSF as appropriate to confirm that the TOE operates as specified. Application Note: The choice of the subset to be tested and the sample of tests executed by the evaluator are entirely at the discretion of the evaluator. 5.3 Security Requirements for the IT Environment The IT environment consists of those administrative processes to ensure Personnel Security, Communications Security, Physical Security, and Cyber Security requirements are met for the TOE as well as the adjudication of varying Cyber security requirements for interconnected systems or networks.

PP APPLICATION NOTES The Discretionary Access Control Policy, also referred to as DAC, is the basic policy that OPENPP compliant systems and products enforce over users and resources. Whether a user is granted a requested action, is determined by the TOE Security Policy (TSP) that is specified in this profile in the context of Discretionary Access Control (DAC). The DAC policy is the set of rules used to mediate user access to TOE protected objects and can be generally characterized as a policy which requires the TOE to allow authenticated users and administrators to control access to objects based on individual user identification. When the DAC policy rules are invoked, the TOE is said to be mediating access to TOE protected objects. However, there may be instances when the DAC policy is not invoked meaning that there may be objects residing in the TOE that are not protected by the TSP. In these instances the TOE is said to not be mediating access to a set of objects even though the TOE is executing a (possibly unauthorized) user request.

The DAC policy consists of two types of rules: those that apply to the behavior of authorized users (termed access rules) and those that apply to the behavior of administrators (termed authorization rules). If an authorized user is granted a request to operate on an object, the user is said to have access to that object. There are numerous types of access; typical ones include read access and write access, which allow the reading and writing of objects respectively. If an administrator is granted a requested service, the user is said to have authorization to the requested service or object. As for access, there are numerous possible authorizations.
