Ensure a Login Window Banner Exists

SrednjaNivo 2Automatskamacos

Opis

A Login window banner warning informs the user that the system is reserved for authorized use only. It enforces an acknowledgment by the user that they have been informed of the use policy in the banner if required. The system recognizes either the .txt and the .rtf formats. An access warning may reduce a casual attacker's tendency to target the system. Access warnings may also aid in the prosecution of an attacker by evincing the attacker's knowledge of the system's private status, acceptable use policy, and authorization requirements.
