Policy and Procedures

Control Text¶

a. Develop, document, and disseminate to [Assignment: organization-defined personnel or roles]: 1. [Selection (one or more): organization-level; mission/business process-level; system-level] access control policy that: (a) Addresses purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance; and (b) Is consistent with applicable laws, executive orders, directives, regulations, policies, standards, and guidelines; and 2. Procedures to facilitate the implementation of the access control policy and the associated access controls; b. Designate an [Assignment: organization-defined official] to manage the development, documentation, and dissemination of the access control policy and procedures; and c. Review and update the current access control: 1. Policy [Assignment: organization-defined frequency]; and 2. Procedures [Assignment: organization-defined frequency].

Discussion¶

This control addresses policy and procedures for the controls in the AC family implemented within systems and organizations. The risk management strategy is an important factor in establishing such policies and procedures. Policies and procedures help provide security and privacy assurance. Therefore, it is important that security and privacy programs collaborate on their development. Security and privacy program policies and procedures at the organization level are preferable, in general, and may obviate the need for system-specific policies and procedures. The policy can be included as part of the general security and privacy policy or can be represented by multiple policies reflecting the complex nature of organizations. Procedures can be established for security and privacy programs and for systems, if needed. Procedures describe how the policies or controls are implemented and can be directed at the individual or role that is the object of the procedure. Procedures can be documented in system security and privacy plans or in one or more separate documents. Restating controls does not constitute an organizational policy or procedure.

Audit¶

This is an organization control to ensure that the account structures makes sense for the business along with the procedures or policy and account creation. The NGFW should be reviewed to ensure that only the allowed accounts are created on the NGFW’s and Panorama.

Align account management processes with personnel termination and transfer processes.

Discussion¶

Examples of system account types include individual, shared, group, system, guest, anonymous, emergency, developer, temporary, and service. Identification of authorized system users and the specification of access privileges reflects the requirements in other controls in the security plan. Users requiring administrative privileges on system accounts receive additional scrutiny by organizational personnel responsible for approving such accounts and privileged access, including system owner, mission or business owner, senior agency information security officer, or senior agency official for privacy. External system accounts are not included in the scope of this control. Organizations address external system accounts through organizational policy. Where access involves personally identifiable information, security programs collaborate with the senior agency official for privacy on establishing the specific conditions for group and role membership; specifying for each account, authorized users, group and role membership, and access authorizations; and creating, adjusting, or removing system accounts in accordance with organizational policies. Policies can include such information as account expiration dates or other factors triggering the disabling of accounts. Organizations may choose to define access privileges or other attributes by account, by type of account, or a combination of the two. Examples of other attributes required for authorizing access include restrictions on time-of-day, day-of-week, and point-of-origin. In defining other system account attributes, organizations consider system-related requirements and mission/business requirements. Failure to consider these factors could affect system availability. Temporary and emergency accounts are intended for short-term use. Organizations establish temporary accounts as a part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. Organizations establish emergency accounts in response to crisis situations and with the need for rapid account activation. Therefore, emergency account activation may bypass normal account authorization processes. Emergency and temporary accounts are not to be confused with infrequently used accounts, including local logon accounts used for special tasks or when network resources are unavailable (may also be known as accounts of last resort). Such accounts remain available and are not subject to automatic disabling or removal dates. Conditions for disabling or deactivating accounts include when shared/group, emergency, or temporary accounts are no longer required; and when individuals are transferred or terminated. Changing shared/group account credentials when members leave the group is intended to ensure that former group members do not retain access to the shared or group account. Some types of system accounts may require specialized training.

Discussion¶

Specifying and enforcing usage conditions helps to enforce the principle of least privilege, increase user accountability, and enable effective account monitoring. Account monitoring includes alerts generated if the account is used in violation of organizational parameters. Organizations can describe specific conditions or circumstances under which system accounts can be used, for example, by restricting usage to certain days of the week, time of day, or specific durations of time.

The Palo Alto NGFW does not allow under-priviledged actions by a particular user/group. In the GUI, certain non-permitted functions will be greyed out as to deny the user that capability. So there will not be a log event for an attempt to essentially escalate privileges as the user is unable to perform them at all. In the Monitor->Configuration section, there is a Results section which will state Success or Fail. Fail could be for many reasons such as unauthorized or the configuration is invalid.

Access Enforcement | Role-based Access Control

Control Text¶

Enforce a role-based access control policy over defined subjects and objects and control access based upon [Assignment: organization-defined roles and users authorized to assume such roles].

Discussion¶

Role-based access control (RBAC) is an access control policy that enforces access to objects and system functions based on the defined role (i.e., job function) of the subject. Organizations can create specific roles based on job functions and the authorizations (i.e., privileges) to perform needed operations on the systems associated with the organization-defined roles. When users are assigned to the specific roles, they inherit the authorizations or privileges defined for those roles. RBAC simplifies privilege administration for because privileges are not assigned directly to every user (which can potentially be a large number of individuals) but are instead acquired through role assignments. RBAC can be implemented as a mandatory or discretionary form of access control. For those organizations implementing RBAC with mandatory access controls, the requirements in AC-3(3) define the scope of the subjects and objects covered by the policy.

Related Controls¶

Audit¶

Discussion¶

Revocation of access rules may differ based on the types of access revoked. For example, if a subject (i.e., user or process acting on behalf of a user) is removed from a group, access may not be revoked until the next time the object is opened or the next time the subject attempts a new access to the object. Revocation based on changes to security labels may take effect immediately. Organizations provide alternative approaches on how to make revocations immediate if systems cannot provide such capability and immediate revocation is necessary.

Audit¶

Access Enforcement | Attribute-based Access Control

Control Text¶

Enforce attribute-based access control policy over defined subjects and objects and control access based upon [Assignment: organization-defined attributes to assume access permissions].

Discussion¶

Attribute-based access control is an access control policy that restricts system access to authorized users based on specified organizational attributes (e.g., job function, identity); action attributes (e.g., read, write, delete); environmental attributes (e.g., time of day, location); and resource attributes (e.g., classification of a document). Organizations can create rules based on attributes and the authorizations (i.e., privileges) to perform needed operations on the systems associated with the organization-defined attributes and rules. When users are assigned to attributes defined in attribute-based access control policies or rules, they can be provisioned to a system with the appropriate privileges or dynamically granted access to a protected resource upon access. Attribute-based access control can be implemented as a mandatory or discretionary form of access control. For attribute-based access control implemented with mandatory access controls, the requirements in AC-3(3) define the scope of the subjects and objects covered by the policy.

Related Controls¶

Discussion¶

Information flow enforcement mechanisms compare security and privacy attributes associated with information (i.e., data content and structure) and source and destination objects and respond appropriately when the enforcement mechanisms encounter information flows not explicitly allowed by information flow policies. For example, an information object labeled Secret would be allowed to flow to a destination object labeled Secret, but an information object labeled Top Secret would not be allowed to flow to a destination object labeled Secret. A dataset of personally identifiable information may be tagged with restrictions against combining with other types of datasets, and therefore, would not be allowed to flow to the restricted dataset. Security and privacy attributes can also include source and destination addresses employed in traffic filter firewalls. Flow enforcement using explicit security or privacy attributes can be used, for example, to control the release of certain types of information.

Related Controls¶

Discussion¶

Embedding data types within other data types may result in reduced flow control effectiveness. Data type embedding includes inserting files as objects within other files and using compressed or archived data types that may include multiple embedded data types. Limitations on data type embedding consider the levels of embedding and prohibit levels of data type embedding that are beyond the capability of the inspection tools.

One-way flow mechanisms may also be referred to as a unidirectional network, unidirectional security gateway, or data diode. One-way flow mechanisms can be used to prevent data from being exported from a higher impact or classified domain or system, while permitting data from a lower impact or unclassified domain or system to be imported.

Information Flow Enforcement | Security and Privacy Policy Filters

Control Text¶

[Selection (one or more): block; strip; modify; quarantine] data after a filter processing failure in accordance with [Assignment: organization-defined security or privacy policy].

Discussion¶

Organization-defined security or privacy policy filters can address data structures and content. For example, security or privacy policy filters for data structures can check for maximum file lengths, maximum field sizes, and data/file types (for structured and unstructured data). Security or privacy policy filters for data content can check for specific words enumerated values or data value ranges, and hidden content. Structured data permits the interpretation of data content by applications. Unstructured data refers to digital information without a data structure or with a data structure that does not facilitate the development of rule sets to address the sensitivity of the information conveyed by the data or the flow enforcement decisions. Unstructured data consists of bitmap objects that are inherently non-language-based (i.e., image, video, or audio files); and textual objects that are based on written or printed languages. Organizations can implement more than one security or privacy policy filter to meet information flow control objectives.

Data type identifiers include filenames, file types, file signatures or tokens, and multiple internal file signatures or tokens. Systems allow transfer of data only if compliant with data type format specifications. Identification and validation of data types is based on defined specifications associated with each allowed data format. The filename and number alone are not used for data type identification. Content is validated syntactically and semantically against its specification to ensure it is the proper data type.

Audit¶

File Blocking Profiles allow you to identify specific file types that you want to want to block or monitor. For most traffic (including traffic on your internal network) you will want to block files that are known to carry threats or that have no real use case for upload/download. Currently, these include batch files, DLLs, Java class files, help files, Windows shortcuts (.lnk), and BitTorrent files. Additionally, to provide drive-by download protection, allow download/upload of executables and archive files (.zip and .rar), but force users to acknowledge that they are transferring a file so that they will notice that the browser is attempting to download something they were not aware of. For policy rules that allow general web browsing, be more strict with your file blocking because the risk of users unknowingly downloading malicious files is much higher. For this type of traffic you will want to attach a more strict file blocking profile that also blocks portable executable (PE) files.

Unsuccessful Logon Attempts

Control Text¶

Enforce a limit of [Assignment: organization-defined number] consecutive invalid logon attempts by a user during a [Assignment: organization-defined time-period]; and
Automatically [Selection (one or more): lock the account or node for an [Assignment: organization-defined time-period]
; lock the account or node until released by an administrator; delay next logon prompt per [Assignment: organization-defined delay algorithm] ; notify system administrator; take other [Assignment: organization-defined action] ] when the maximum number of unsuccessful attempts is exceeded.

Discussion¶

This control applies regardless of whether the logon occurs via a local or network connection. Due to the potential for denial of service, automatic lockouts initiated by systems are usually temporary and automatically release after a predetermined, organization-defined time period. If a delay algorithm is selected, organizations may employ different algorithms for different components of the system based on the capabilities of those components. Responses to unsuccessful logon attempts may be implemented at the operating system and the application levels. Organization-defined actions that may be taken when the number of allowed consecutive invalid logon attempts is exceeded include prompting the user to answer a secret question in addition to the username and password; invoking a lockdown mode with limited user capabilities (instead of full lockout); or comparing the IP address to a list of known IP addresses for the user and then allowing additional logon attempts if the attempts are from a known IP address. Techniques to help prevent brute force attacks in lieu of an automatic system lockout or the execution of delay algorithms support the objective of availability while still protecting against such attacks. Techniques that are effective when used in combination include prompting the user to respond to a secret question before the number of allowed unsuccessful logon attempts is exceeded; allowing users to logon only from specified IP addresses; requiring a CAPTCHA to prevent automated attacks; or applying user profiles such as location, time of day, IP address, device, or MAC address. Automatically unlocking an account after a specified period of time is generally not permitted. However, exceptions may be required based on operational mission or need.

Discussion¶

A mobile device is a computing device that has a small form factor such that it can be carried by a single individual; is designed to operate without a physical connection; possesses local, non-removable or removable data storage; and includes a self-contained power source. Purging or wiping the device applies only to mobile devices for which the organization-defined number of unsuccessful logons occurs. The logon is to the mobile device, not to any one account on the device. Successful logons to accounts on mobile devices reset the unsuccessful logon count to zero. Purging or wiping may be unnecessary if the information on the device is protected with sufficiently strong encryption mechanisms.

Discussion¶

Information is represented internally within systems using abstractions known as data structures. Internal data structures can represent different types of entities, both active and passive. Active entities, also known as subjects, are typically associated with individuals, devices, or processes acting on behalf of individuals. Passive entities, also known as objects, are typically associated with data structures such as records, buffers, tables, files, inter-process pipes, and communications ports. Security attributes, a form of metadata, are abstractions representing the basic properties or characteristics of active and passive entities with respect to safeguarding information. Privacy attributes, which may be used independently, or in conjunction with security attributes, represent the basic properties or characteristics of active or passive entities with respect to the management of personally identifiable information. Attributes can be either explicitly or implicitly associated with the information contained in organizational systems or system components. Attributes may be associated with active entities (i.e., subjects) that have the potential to send or receive information, to cause information to flow among objects, or to change the system state. These attributes may also be associated with passive entities (i.e., objects) that contain or receive information. The association of attributes to subjects and objects by a system is referred to as binding and is inclusive of setting the attribute value and the attribute type. Attributes, when bound to data or information, permit the enforcement of security and privacy policies for access control and information flow control, including data retention limits, permitted uses of personally identifiable information, and identification of personal information within data objects. Such enforcement occurs through organizational processes or system functions or mechanisms. The binding techniques implemented by systems affect the strength of attribute binding to information. Binding strength and the assurance associated with binding techniques play an important part in the trust organizations have in the information flow enforcement process. The binding techniques affect the number and degree of additional reviews required by organizations. The content or assigned values of attributes can directly affect the ability of individuals to access organizational information. Organizations can define the types of attributes needed for systems to support missions or business functions. There are many values that can be assigned to a security attribute. Release markings include US only, NATO (North Atlantic Treaty Organization), or NOFORN (not releasable to foreign nationals). By specifying the permitted attribute ranges and values, organizations ensure that attribute values are meaningful and relevant. Labeling refers to the association of attributes with the subjects and objects represented by the internal data structures within systems. This facilitates system-based enforcement of information security and privacy policies. Labels include classification of information in accordance with legal and compliance requirements; access authorizations; nationality; data life cycle protection (i.e., encryption and data expiration); personally identifiable information processing permissions; individual consent to personally identifiable information processing; and affiliation as a contractor. Conversely, marking refers to the association of attributes with objects in a human-readable form. Marking enables manual, procedural, or process-based enforcement of information security and privacy policies. Attribute types include classification level for objects and clearance (access authorization) level for subjects. An attribute value for both attribute types is Top Secret.

Discussion¶

Dynamic association of attributes is appropriate whenever the security or privacy characteristics of information change over time. Attributes may change due to information aggregation issues (i.e., characteristics of individual data elements are different from the combined elements); changes in individual access authorizations (i.e., privileges); changes in the security category of information; or changes in security or privacy policies. Attributes may also change situationally.

To enforce security and privacy policies across multiple system components in distributed systems, organizations provide a consistent interpretation of security and privacy attributes employed in access enforcement and flow enforcement decisions. Organizations can establish agreements and processes to help ensure that distributed system components implement attributes with consistent interpretations in automated access enforcement and flow enforcement actions.

Audit¶

The association of security and privacy attributes to information within systems is important for conducting automated access enforcement and flow enforcement actions. The association of such attributes to information (i.e., binding) can be accomplished with technologies and techniques providing different levels of assurance.

Discussion¶

A regrading mechanism is a trusted process authorized to re-classify and re-label data in accordance with a defined policy exception. Validated regrading mechanisms are used by organizations to provide the requisite levels of assurance for attribute reassignment activities. The validation is facilitated by ensuring that regrading mechanisms are single purpose and of limited function. Since security and privacy attribute changes can directly affect policy enforcement actions, implementing trustworthy regrading mechanisms is necessary to help ensure that such mechanisms perform in a consistent and correct mode of operation.
