By default, strangers can't do anything to an ARES-powered robot without its permission, aside from shoot it. Attempting to access the menus or run a command will cause a consent alert to appear in the top-left corner of the screen, which looks like this:

With the ARES Alert Response Gestures activated (see Getting Equipped in Booting up for the first time), you can press F2, F3, F4, or F5 to respond.

• Allow (F2): Complete the action, and permit further actions by the person or object until they have been inactive for 30 seconds.
• Trust (F3): Complete the action, and permit all further actions by the person or object with no time limit.
• Reject (F4): Prevent the action and all further actions until the person or object has left you alone for at least 30 seconds.
• Blacklist (F5): Refuse all actions from the person or object with no time limit.

A person whom you grant consent is called a guest. If you pressed F2, they are considered a temporary guest. If you pressed F3, they are a permanent guest. Likewise, rejecting a request causes a temporary ban and blocking a request causes a permanent ban. When a temporary guest or ban expires, the affected person or object reverts to being treated like a stranger.

Unlike other forms of authorized user, guests and bans are meant to be managed by the unit, not the owner. They are stored separately in the security database, and both lists can be wiped clean by a system administrator (manager or owner) by visiting the access control menu. Later tutorials will explain how to disable the entire consent mechanism for those who want to have a fully private or fully public unit.
