Check Text ( C-69551r997301_chk )
Review the application documentation, system security plan and interview the application administrator to determine if the application processes classified data. If the application does not process classified data, this requirement is not applicable. Identify the data classifications and the cryptographic protections established to protect the application data. Verify the application is configured to utilize the appropriate encryption based upon data classification, cryptographic tasks that need to be performed (information protection, hashing, signing) and information protection requirements. NIST-certified cryptography must be used to store classified non-Sources and Methods Intelligence (SAMI) information if required by the information owner. NSA-validated type-1 encryption must be used for all SAMI data stored in the enclave. If the application is not configured to utilize the NSA-approved cryptographic modules in accordance with data protection requirements specified in the security plan, this is a finding.
