| Description |
|---|
| Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session. Quickly terminating an idle session also frees up resources. This requirement does not mean that the device terminates all sessions or network access; it only ends the inactive session. User accounts, including the account of last resort must be assigned to a login class. Configure all login classes with an idle timeout value. Pre-defined classes do not support configurations, therefore should not be used for DoD implementations. The root account cannot be assigned to a login-class which is why it is critical that this account be secured in accordance with DoD policy. |
| ℹ️ Check |

| Verify idle-timeout is set for 10 minutes. [edit] show system login If a timeout value of 10 or less is not set for each class, this is a finding. |
