Maintaining Login Control

You also must restrict unauthorized logins to a system or the network, which you can do through password and login control. All accounts on a system should have a password. An account without a password makes your entire network accessible to anyone who can guess a user name.

Solaris software restricts control of certain system devices to the user login account. Only a process that is running as superuser or console user can access a system mouse, keyboard, frame buffer, or audio device unless the /etc/logindevperm file is edited. For more information, see logindevperm(4).
