Ensure sshd LoginGraceTime is configured

SrednjaNivo 1Automatskalinux

Opis

The LoginGraceTime parameter specifies the time allowed for successful authentication to the SSH server. The longer the Grace period is the more open unauthenticated connections can exist. Like other session controls in this section the Grace Period should be limited to appropriate organizational limits to ensure the service is available for needed access.
