The Photon operating system must configure sshd to restrict LoginGraceTime.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| 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. |
