The Photon operating system must configure sshd to restrict LoginGraceTime.

| 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. | ||||
