Check Text ( C-72477r1_chk )
Verify the SSH daemon does not allow authentication using known hosts authentication. To determine how the SSH daemon's "IgnoreRhosts" option is set, run the following command: # grep -i IgnoreRhosts /etc/ssh/sshd_config IgnoreRhosts yes If the value is returned as "no", the returned line is commented out, or no output is returned, this is a finding.

Fix Text (F-78597r2_fix)
Configure the SSH daemon to not allow authentication using known hosts authentication. Add the following line in "/etc/ssh/sshd_config", or uncomment the line and set the value to "yes": IgnoreRhosts yes
