| Description |
|---|
| By default, sshd 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 resources and reduce the exposure any partial logon attempts may create. |
| ℹ️ Check |
|---|
| At the command line, run the following command: # sshd -T|&grep -i LoginGraceTime Expected result: logingracetime 30 If the output does not match the expected result, this is a finding. |
| ✔️ 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 |
