Perimeter Defense
Perimeter defense is a security approach that establishes a secure boundary, like a digital fence, around a network to block unauthorized access. It acts as the first line of defense, designed to keep external threats from getting inside.
TECHNICAL DEFINITION
Perimeter defense is a network security model focused on protecting the boundary between an internal, trusted network and an untrusted external network using components like firewalls, intrusion prevention systems (IPS/IDS), and demilitarized zones (DMZs). This security architecture enforces strict access control policies at the network edge to prevent unauthorized access and mitigate external cyber threats.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.

USAGE NOTE
The traditional 'castle-and-moat' approach of perimeter defense is now considered insufficient on its own and is often supplemented by a Zero Trust architecture.
