Assessment Procedure

Check Text

Check the SSH client configuration for allowed protocol versions. Note that keywords are case-insensitive and arguments (args) are case-sensitive. 

keyword=Protocol
arg(s)=2

# cat /opt/ssh/etc/ssh_config | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v '^#' | grep -i "Protocol"

If Protocol 2,1 (the default) or Protocol 1 are defined on a line without a leading comment, this is a finding.

Implementation Procedure

Fix Text

Edit the client configuration file Protocol entry to look like:
