Appendix F Security Control Catalog
Security Controls, Supplemental Guidance, and Control Enhancements
The following catalog of security controls provides a range of safeguards and countermeasures for information systems. The security controls are organized into families for ease of use in the control selection and specification process. Each family contains security controls related to the security function of the family. A standardized, two-character identifier is assigned to uniquely identify each control family. To uniquely identify each control, a numeric identifier is appended to the family identifier to indicate the number of the control within the control family.
The security control structure consists of three key components:
- A control section
- A supplemental guidance section
- A control enhancements section
The control section provides a concise statement of the specific security capability needed to protect a particular aspect of an information system. The control statement describes specific security-related activities or actions to be carried out by the organization or by the information system. For some controls in the control catalog, a degree of flexibility is provided by allowing organizations to selectively define input values for certain parameters associated with the controls. This flexibility is achieved through the use of assignment and selection operations within the main body of the control.
The supplemental guidance section provides additional information related to a specific security control. Organizations should consider supplemental guidance when defining, developing, and implementing security controls. Applicable federal legislation, executive orders, directives, policies, regulations, standards, and guidance documents (e.g., OMB Circulars, FIPS, and NIST Special Publications) are listed in the supplemental guidance section, when appropriate, for the particular security control. The control enhancements section provides statements of security capability to (1) build in additional, but related, functionality to a basic control and/or (2) increase the strength of a basic control. In both cases, the control enhancements are used in an information system requiring greater protection because of greater potential impact of loss or when organizations seek additions to a basic control’s functionality based on the results of a risk assessment. Control enhancements are numbered sequentially within each control so that the enhancements can be easily identified when selected to supplement the basic control.
With regard to cryptography employed in federal information systems, organizations must comply with current federal policy and meet the requirements of FIPS 140-2, Security Requirements for Cryptographic Modules. The FIPS 140-2 standard also acknowledges the use of cryptography approved by the National Security Agency as an appropriate alternative for organizations. Consult FIPS 140-2 for specific guidance.

AC-2 ACCOUNT MANAGEMENT
Control
The organization manages information system accounts, including establishing, activating, modifying, reviewing, disabling, and removing accounts. The organization reviews information system accounts [Assignment: organization-defined frequency].
Supplemental Guidance
Account management includes the identification of account types (i.e., individual, group, and system), establishment of conditions for group membership, and assignment of associated authorizations. The organization identifies authorized users of the information system and specifies access rights/privileges. The organization grants access to the information system based on: (i) a valid need-to-know that is determined by assigned official duties and satisfying all personnel security criteria; and (ii) intended system usage. The organization requires proper identification for requests to establish information system accounts and approves all such requests. The organization specifically authorizes and monitors the use of guest/anonymous accounts and removes, disables, or otherwise secures unnecessary accounts. The organization ensures that account managers are notified when information system users are terminated or transferred and associated accounts are removed, disabled, or otherwise secured. Account managers are also notified when users’ information system usage or need-to-know changes.
Control Enhancements
(1) The organization employs automated mechanisms to support the management of information system accounts.
(2) The information system automatically terminates temporary and emergency accounts after [Assignment: organization-defined time period for each type of account].

AC-3 ACCESS ENFORCEMENT
Control
The information system enforces assigned authorizations for controlling access to the system in accordance with applicable policy.
Supplemental Guidance
Access control policies (e.g., identity-based policies, role-based policies, ruled-based policies) and associated access enforcement mechanisms (e.g., access control lists, access control matrices, cryptography) are employed by organizations to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, domains) in the information system. In addition to controlling access at the information system level, access enforcement mechanisms are employed at the application level, when necessary, to provide increased information security for the organization. If encryption of stored information is employed as an access enforcement mechanism, the cryptography used is FIPS 140-2 compliant.
Control Enhancements
(1) The information system ensures that access to security functions (deployed in hardware, software, and firmware) and information is restricted to authorized personnel (e.g., security administrators).

AC-4 INFORMATION FLOW ENFORCEMENT
Control
The information system enforces assigned authorizations for controlling the flow of information within the system and between interconnected systems in accordance with applicable policy.
Supplemental Guidance
Information flow control policies and enforcement mechanisms are employed by organizations to control the flow of information between designated sources and destinations (e.g., individuals, devices) within information systems and between interconnected systems based on the characteristics of the information. Simple examples of flow control enforcement can be found in firewall and router devices that employ rule sets or establish configuration settings that restrict information system services or provide a packet filtering capability. Flow control enforcement can also be found in information systems that use explicit labels on information, source, and destination objects as the basis for flow control decisions (e.g., to control the release of certain types of information).

The information system monitors and controls communications at the external boundary of the information system and at key internal boundaries within the system.
Supplemental Guidance
Any connections to the Internet, or other external networks or information systems, occur through controlled interfaces (e.g., proxies, gateways, routers, firewalls, encrypted tunnels). The operational failure of the boundary protection mechanisms does not result in any unauthorized release of information outside of the information system boundary. Information system boundary protections at any designated alternate processing sites provide the same levels of protection as that of the primary site.
Control Enhancements
(1) The organization physically allocates publicly accessible information system components (e.g., public web servers) to separate subnetworks with separate, physical network interfaces. The organization prevents public access into the organization’s internal networks except as appropriately mediated.
