CHAPTER 4
Understanding Intrusion-Detection and Reporting Systems
While preventing unauthorized access is the first line of defense in physical security, layers of additional security measures are crucial to preventing intrusions from escalating into serious events. A closely related second tier of defense is intrusion detection, which enables potential intruders to be detected and removed before they can cause problems. This level of security involves detection devices that are monitored or that can create an alarm. In this chapter, you’ll learn to:
- Describe components of a typical, physical intrusion-detection and reporting system
- Explain the purpose for creating physical security zones and common techniques for defining them
- Identify common sensor types employed in a physical intrusion-detection system.
Intrusion-Detection and Reporting Systems
The components of a basic commercial security system, as depicted in Figure 4.1, come together to provide a functional intrusion...
