name: Set SSH Idle Timeout Interval
|

description: |
|
|
Missing an SSH idle timeout interval can lead to security risks by allowing unattended sessions to remain open, increasing the chance of unauthorized access or session hijacking.
|
|
remediation: |
|
|
Set ClientAliveInterval 300 and ClientAliveCountMax 0 in /etc/ssh/sshd_config to enforce an idle timeout and restart the SSH service.
