SC-11(1) Irrefutable Communications Path
Control enhancement of SC-11 Trusted Path
Control
Provide a trusted communications path that is irrefutably distinguishable from other communications paths; and
Initiate the trusted communications path for communications between the [Assignment: security functions] of the system and the user.
Discussion
An irrefutable communications path permits the system to initiate a trusted path, which necessitates that the user can unmistakably recognize the source of the communication as a trusted system component. For example, the trusted path may appear in an area of the display that other applications cannot access or be based on the presence of an identifier that cannot be spoofed.

We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
