As a physical security tester, or physical penetration tester, you examine the physical security systems of a facility. Your duties frequently focus on manually testing security equipment such as alarm systems, ID scanners, metal detectors, and surveillance equipment. You may also try to get around physical barriers such as fences or locks. Your goals during a test are to find and define any vulnerability within the facility’s security system. After you try to breach the security system at a facility, your responsibilities include reporting the results and suggesting improvements to control access.
