GEN005507 - The SSH daemon must be configured to only use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hash algorithms - MACs that employ FIPS 140-2 cryptographic hash algorithms.


DoD information systems are required to use FIPS 140-2 approved cryptographic hash functions.


Edit the SSH daemon configuration and remove any MACs that are not hmac-sha1 or a better hmac algorithm that is on the FIPS 140-2 approved list. If necessary, add a MACs line.

Restart the SSH daemon.
# /sbin/service sshd restart
