SC-3(2) Access and Flow Control Functions
Control enhancement of SC-3 Security Function Isolation
Control
Isolate security functions enforcing access and information flow control from nonsecurity functions and from other security functions.
Discussion
Security function isolation occurs because of implementation. The functions can still be scanned and monitored. Security functions that are potentially isolated from access and flow control enforcement functions include auditing, intrusion detection, and malicious code protection functions.
Need SC-3(2) implemented and evidenced?
We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
