What is the 4D Concept in Physical Security?

The ‘4 Ds of Physical Security’ sum up four critical elements to foster foolproof protection.
1. Deter – It focuses on setting up barriers to prevent intrusion attempts.
2. Detect – The aim is to promptly identify breaches via surveillance or alarm systems.
3. Delay – This indicates slowing down intruders until help arrives.
4. Deny – This involves denying entry into sensitive areas entirely or without proper authorization.
Deter, Detect, Delay, and Deny are crucial for optimum physical security!
