security zone
Restricted access region
A security zone is a designated area where access, movement, or activities are restricted for protection purposes.
The term applies across contexts: military buffer zones between hostile forces, protected perimeters around buildings or events, and cordoned-off areas during emergencies.
In computing, security zones classify websites or networks by trust level, determining what code can run.
