perimeter defense
Guarding outer edges
Perimeter defense is a security strategy focused on protecting boundaries rather than interior spaces.
In military contexts, forces establish defensive positions around a camp or territory's outer edges.
The concept extends to cybersecurity, where firewalls and access controls guard network boundaries: Traditional perimeter defense assumes threats come from outside.
The approach has limitations when threats originate within.
