CHAPTER 10

Physical Security

This chapter is supplemental to and coordinated with the Physical Security chapter in the CISSP Prep Guide. The fundamentals of Physical Security are covered in Chapter 10 of the CISSP Prep Guide at a level commensurate with that of the CISSP Examination.

These advanced questions and answers build upon the questions and answers covered in Chapter 10 of the CISSP Prep Guide. While these questions may be more difficult than the actual questions on the exam, they are good preparation for the concepts covered, such as fire suppression, physical access control, and physical intrusion detection.
