Requirements NIST SOURCE

Protect the availability of resources by allocating [resources] by [one of: priority; quota; ].

Discussion (NIST Supplemental Guidance)

Priority protection prevents lower-priority processes from delaying or interfering with the system that services higher-priority processes. Quotas prevent users or processes from obtaining more than predetermined amounts of resources.

No engineering interpretation has been authored for SC-6 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. resources to be allocated to protect the availability of resources are defined;
  2. one or more of the following PARAMETER VALUES is/are selected: {priority; quota; <SC-06_ODP[03] controls>};
  3. controls to protect the availability of resources are defined (if selected);
  4. the availability of resources is protected by allocating <SC-06_ODP[01] resources> by <SC-06_ODP[02] SELECTED PARAMETER VALUES>.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing prioritization of system resources; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; system developer].

Test

[SELECT FROM: Mechanisms supporting and/or implementing a resource allocation capability; safeguards employed to protect availability of resources].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-6. 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.
