Assessment Objective

Determine if:

• SC-28(01)[01] cryptographic mechanisms are implemented to prevent unauthorized disclosure of [Assignment: information] at rest on [Assignment: system components or media];
• SC-28(01)[02] cryptographic mechanisms are implemented to prevent unauthorized modification of [Assignment: information] at rest on [Assignment: system components or media].
