Fix Recommendation

Edit /etc/ssh/sshd_config and change or set the Ciphers line to the following.

Ciphers aes256-ctr, aes192-ctr, aes128-ctr

Check Contents

Check the SSH daemon configuration for allowed ciphers.

# grep -i ciphers /etc/ssh/sshd_config | grep -v '^#'

Ciphers aes256-ctr,aes192-ctr,aes128-ctr

If any ciphers other than "aes256-ctr", "aes192-ctr", or "aes128-ctr" are listed, the order differs from the example above, the "Ciphers" keyword is missing, or is commented out, this is a finding.
