CCI-001086

Isolate security functions enforcing access and information flow control from both nonsecurity functions and from other security functions.

Implementation Guidance

Determine if: - security functions enforcing access control are isolated from non-security functions. - security functions enforcing access control are isolated from other security functions. - security functions enforcing information flow control are isolated from non-security functions. - security functions enforcing information flow control are isolated from other security functions.

Validation Procedures

Examine: [SELECT FROM: System and communications protection policy; procedures addressing security function isolation; list of critical security functions; 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: Isolation of security functions enforcing access and information flow control].
