Check Text ( C-30053r490078_chk )
Check the SSH client configuration for allowed protocol versions.
# grep -i protocol /etc/ssh/ssh_config | grep -v '^#'
If the returned protocol configuration allows versions less than 2, this is a finding.
Fix Text (F-30041r490079_fix)
Edit the /etc/ssh/ssh_config file and add or edit a Protocol configuration line that does not allow versions less than 2.
