Fix Recommendation

The root role is required.

Modify the sshd_config file.

# pfedit /etc/ssh/sshd_config

Change or set the ciphers line to the following:

ciphers aes256-ctr,aes192-ctr,aes128-ctr

Restart the SSH service.

# svcadm restart svc:/network/ssh

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.
