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
