Detailed Policy Requirements:
Site WMAN systems that transmit classified data must implement the following data encryption controls:
- The WMAN system must implement FIPS 140-2 validated encryption to protect the ISO OSI Layer 2 radio data frames. The WMAN system will be configured for AES-CCM encryption, if supported by the WMAN system. (Not required for classified WMAN bridges.)
- The WMAN system must implement NSA Type 1 certified High Assurance Internet Protocol Encryptor (HAIPE) encryption, other NSA Type 1 certified encryption, or NSA approved Suite B overlay encryption at ISO OSI Layer 3 to protect data being transmitted.
Check Procedures:
Review the WMAN product specification sheets.
- Verify FIPS 140-2 validated encryption is being used at OSI Layer 2 to protect the radio data frames.
- Determine if the system supports AES-CCM encryption. If yes, verify the system has been configured for AES-CCM encryption.
- Verify NSA Type 1 certified High Assurance Internet Protocol Encryptor (HAIPE) encryption, other NSA Type 1 certified encryption, or NSA approved Suite B overlay encryption is being used at OSI Layer 3 to protect data being transmitted.
Mark as a finding if any of these requirements have not been met.
