Description
The banner must be acknowledged by the administrator prior to the device allowing the administrator access to the network device. This ensures the administrator has seen the message and accepted the conditions for access. If the consent banner is not acknowledged by the administrator, DoD will not be in compliance with system use notifications required by law. To establish acceptance of the network administration policy, a click-through banner at management session logon is required. The device must prevent further activity until the administrator executes a positive action to manifest agreement. In the case of CLI access using a terminal client, entering the username and password when the banner is presented is considered an explicit action of acknowledgement. Entering the username, viewing the banner, then entering the password is also acceptable.
