defensive perimeter
Guarded outer edge
A defensive perimeter is a boundary established to protect a position from attack, whether a military installation, a guarded facility, or a sports goal.
Troops or guards are stationed along it to detect and repel threats.
The term extends to any protective boundary: The Secret Service established a defensive perimeter around the building.
In sports like lacrosse or hockey, playing the defensive perimeter means guarding the area around one's own goal.
