Check Text (C-261341r996486_chk)
Verify SLEM 5 SSH daemon performs strict mode checking of home directory configuration files with the following command:
> sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*strictmodes'
/etc/ssh/sshd_config:StrictModes yes
If "StrictModes" is not set to "yes", is commented out, missing, or conflicting results are returned, this is a finding.
Fix Text (F-64978r996485_fix)
Configure SLEM 5 SSH daemon performs strict mode checking of home directory configuration files.
Add or modify the following line in the "/etc/ssh/sshd_config" file:
StrictModes yes
Restart the SSH daemon in order for the changes to take effect:
> sudo systemctl restart sshd.service
