Fix Recommendation

Edit the SSH daemon configuration and remove any MACs other than "hmac-sha1". If necessary, add a "MACs" line.

# sed -i "/^[^#]*MACs/ c\MACs hmac-sha1" /etc/ssh/sshd_config

Check Contents

Check the SSH daemon configuration for allowed MACs:

# 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.
