Fix Recommendation

Update the "Ciphers" directive with the following command:

# sed -i "/^[^#]*Ciphers/ c\Ciphers aes256-ctr,aes128-ctr" /etc/ssh/ssh_config

Save and close the file.

Check Contents

Check the SSH daemon configuration for DoD-approved encryption to protect the confidentiality of SSH remote connections by performing the following commands:

Check the "Ciphers" setting in the "ssh_config" file.

# grep -i Ciphers /etc/ssh/ssh_config | grep -v '#'

The output must contain either nothing or any number of the following algorithms:

aes128-ctr, aes256-ctr.

If the output contains an algorithm not listed above, this is a finding.

Expected Output:
Ciphers aes256-ctr,aes128-ctr
