The Photon operating system must configure Secure Shell (SSH) to restrict LoginGraceTime.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-258884 | PHTN-40-000221 | SV-258884r933713_rule | CCI-000366 | medium |
| Description | ||||
| By default, SSH unauthenticated connections are left open for two minutes before being closed. This setting is too permissive as no legitimate login would need such an amount of time to complete a login. Quickly terminating idle or incomplete login attempts will free up resources and reduce the exposure any partial logon attempts may create. | ||||

Details
Check Text (C-258884r933713_chk)
At the command line, run the following command to verify the running configuration of sshd:
# sshd -T|&grep -i LoginGraceTime
Example result:
logingracetime 30
If "LoginGraceTime" is not set to "30", this is a finding.
Fix Text (F-62533r933712_fix)
Navigate to and open:
/etc/ssh/sshd_config
Ensure the "LoginGraceTime" line is uncommented and set to the following:
LoginGraceTime 30
At the command line, run the following command:
# systemctl restart sshd.service
