Requirements NIST SOURCE

Employ a joint authorization process for the system that includes multiple authorizing officials from the same organization conducting the authorization.

Discussion (NIST Supplemental Guidance)

Assigning multiple authorizing officials from the same organization to serve as co-authorizing officials for the system increases the level of independence in the risk-based decision-making process. It also implements the concepts of separation of duties and dual authorization as applied to the system authorization process. The intra-organization joint authorization process is most relevant for connected systems, shared systems, and systems with multiple information owners.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. a joint authorization process is employed for the system;
  2. the joint authorization process employed for the system includes multiple authorizing officials from the same organization conducting the authorization.

Examine

[SELECT FROM: Assessment, authorization, and monitoring policy; procedures addressing authorization; system security plan; privacy plan; assessment report; plan of action and milestones; authorization statement; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with authorization responsibilities; organizational personnel with information security and privacy responsibilities].

Test

[SELECT FROM: Mechanisms that facilitate authorizations and updates].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CA-6(1). 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.
