Requirements NIST SOURCE

Provide the capability for privileged administrators to enable and disable [organization-defined security or privacy policy filters] under the following conditions: [organization-defined conditions].

Discussion (NIST Supplemental Guidance)

For example, as allowed by the system authorization, administrators can enable security or privacy policy filters to accommodate approved data types. Administrators also have the capability to select the filters that are executed on a specific data flow based on the type of data that is being transferred, the source and destination security domains, and other security or privacy relevant features, as needed.

Implementation Guidance

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(10) 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 enable and disable are defined;
  2. privacy policy filters that privileged administrators have the capability to enable and disable are defined;
  3. conditions under which privileged administrators have the capability to enable and disable security policy filters are defined;
  4. conditions under which privileged administrators have the capability to enable and disable privacy policy filters are defined;
  5. capability is provided for privileged administrators to enable and disable <AC-04(10)_ODP[01] security filters> under <AC-04(10)_ODP[03] conditions>;
  6. capability is provided for privileged administrators to enable and disable <AC-04(10)_ODP[02] privacy filters> under <AC-04(10)_ODP[04] conditions>.

Examine

[SELECT FROM: Access control policy; information flow information policies; procedures addressing information flow enforcement; system design documentation; system configuration settings and associated documentation; list of security policy filters enabled/disabled by privileged administrators; list of privacy policy filters enabled/disabled by privileged administrators; list of approved data types for enabling/disabling by privileged administrators; system audit records; system security plan; privacy plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with responsibilities for enabling/disabling 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(10). 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.
