Requirements NIST SOURCE

Provide the capability for privileged administrators to configure [organization-defined security or privacy policy filters] to support different security or privacy policies.

Discussion (NIST Supplemental Guidance)

Documentation contains detailed information for configuring security or privacy policy filters. For example, administrators can configure security or privacy policy filters to include the list of inappropriate words that security or privacy policy mechanisms check in accordance with the definitions provided by organizations.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for AC-4(11) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. security policy filters that privileged administrators have the capability to configure to support different security and privacy policies are defined;
  2. privacy policy filters that privileged administrators have the capability to configure to support different security and privacy policies are defined;
  3. capability is provided for privileged administrators to configure <AC-04(11)_ODP[01] security policy filters> to support different security or privacy policies;
  4. capability is provided for privileged administrators to configure <AC-04(11)_ODP[02] privacy policy filters> to support different security or privacy policies.

Examine

[SELECT FROM: Access control policy; information flow control policies; procedures addressing information flow enforcement; system design documentation; system configuration settings and associated documentation; list of security policy filters; list of privacy policy filters; system audit records; system security plan; privacy plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with responsibilities for configuring security and privacy policy filters; system/network administrators; organizational personnel with information security and privacy responsibilities; system developers].

Test

[SELECT FROM: Mechanisms implementing information flow enforcement policy; security and privacy policy filters].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AC-4(11). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
