If SSHD is enabled then it _MUST_ be configured to limit the Message Authentication Codes (MACs) to algorithms that are FIPS 140 validated.
FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets federal requirements.
Operating systems utilizing encryption _MUST_ use FIPS validated mechanisms for authenticating to cryptographic modules.
NOTE: /etc/ssh/ssh_config will be automatically modified to its original state following any update or major upgrade to the operating system.
Fix:
/usr/bin/grep -q '^MACs' /etc/ssh/ssh_config && /usr/bin/sed -i.bak 's/.*MACs.*/MACs hmac-sha2-256,hmac-sha2-512/' /etc/ssh/ssh_config; /bin/launchctl kickstart -k system/com.openssh.sshd
Parameter:
[hmac-sha2-256,hmac-sha2-512]
Technical Mechanism:
/usr/bin/grep -q '^MACs' /etc/ssh/ssh_config && /usr/bin/sed -i.bak 's/.*MACs.*/MACs hmac-sha2-256,hmac-sha2-512/' /etc/ssh/ssh_config; /bin/launchctl kickstart -k system/com.openssh.sshd
