Description
The "sudo" command must be configured to prompt for the administrator's password at least once in each newly opened Terminal window or remote logon session, as this prevents a malicious user from taking advantage of an unlocked computer or an abandoned logon session to bypass the normal password prompt requirement. Without the "tty_tickets" option, all open local and remote logon sessions would be authenticated to use sudo without a password for the duration of the configured password timeout window.
