Layered Defense

If you are like most in the security industry,  you are familiar with the idea of having an intrusion detection system with a lock on a door, but layered defense takes the idea much further. The principle behind a layered defense is that it’s much harder for a potential intruder to defeat multiple barriers as opposed to just one. Plus, the idea of delay allows time for a local response to occur before the intruder get to the most sensitive parts of the building or campus.

Here are the primary layers, broken down:

1. Perimeter Security: This is the outermost layer and includes things like fences, walls, or natural barriers like hedges.

2. Territorial Reinforcement: This involves creating a clear distinction between public and private property, which can act as a psychological deterrent. This could be as simple as signage, landscaping, or pathways that guide visitors along certain routes.

3. Building Exterior: Before someone even gets to a door or window, there are other obstacles and deterrents that can be put in place. This includes security cameras, motion-activated lighting, or even guard dogs.

4. Access Control: This is what most people think of when considering physical security. It involves locks, card readers, biometric systems, and more.

5. Internal Security: Even if someone gains access to the building, there can be additional layers inside, such as secure doors to certain wings or rooms, safes, or even security personnel.

6. Operational Procedures: Beyond the physical barriers, there are procedures and protocols that can enhance security. This includes things like requiring ID checks, escorting visitors, preventing piggybacking or tailgating, or having regular security audits.

A key concept behind layered defense is that no single layer is perfect; each has vulnerabilities. However, by having multiple layers, the weaknesses of one layer can be compensated for by the strengths of another and delay and deterrence are increased.

Pro tip: Landscaping can be used as a security tool! For instance, thorny bushes beneath windows can act as a deterrent against someone trying to access them. Similarly, trees and shrubs can be trimmed to ensure they don't provide cover for someone trying to sneak in. Landscaping can also be used to direct foot traffic along desired paths.

Incorporating a comprehensive, layered approach ensures that there are multiple obstacles in the way of potential threats, thereby increasing the overall security of a location. Our team ensures that the ideal security solution is designed and implemented by your contractor(s). This starts with a comprehensive security risk assessment.
