Check Text (C-215299r991589_chk)
Check the SSH daemon configuration for the "StrictModes" setting using command:
# grep -i StrictModes /etc/ssh/sshd_config | grep -v '^#'
StrictModes yes
If the setting is missing or is set to "no", this is a finding.
Fix Text (F-16495r294349_fix)
Edit the "/etc/sshd/sshd_config" file and add or change the "StrictModes" setting to "yes".
Restart the SSH daemon:
# stopsrc -s sshd
# startsrc -s sshd
