A penetration tester is testing the security of a building's alarm system following reports of unauthorized personnel entering the building. Which of the following describes the type of penetration test that is being conducted?

Defensive penetration testing refers to assessing an organization’s defensive measures against attacks, focusing on internal security processes and protocols rather than external threats. While this approach is important for overall security, it does not specifically address the physical aspects of security systems like alarms and access points.

Integrated penetration testing combines various approaches, including physical, application, and network testing, to provide a holistic view of security vulnerabilities. However, the scenario specifically centers on testing the physical alarm system, making "integrated" an inappropriate label for this focused evaluation.

Continuous penetration testing involves ongoing assessments to identify vulnerabilities as they arise over time, often in a dynamic environment. While valuable for maintaining security, this methodology does not apply to the specific situation of testing a building's alarm system for immediate vulnerabilities.
