Check Text ( C-27762r1_chk )
Check the SSH daemon configuration for allowed MACs.

Procedure:
# grep -i macs /etc/ssh/sshd_config | grep -v '^#'

If no lines are returned, or the returned MACs list contains any MAC other than hmac-sha1, this is a finding.
Fix Text (F-24003r1_fix)
Edit the SSH daemon configuration and remove any MACs other than hmac-sha1. If necessary, add a MACs line.
