During a penetration test, a vendor attempts to enter an unauthorized area using an access badge. Which of the following types of tests does this represent?

This scenario describes a physical penetration test. Physical penetration testing involves attempting to bypass physical security controls, such as locks, fences, cameras, and access badges, to gain unauthorized access to facilities or assets. The vendor's attempt to use an access badge to enter an unauthorized area directly falls under this category. Defensive testing refers to activities like vulnerability scanning or security audits aimed at identifying weaknesses from an internal perspective. Passive testing involves monitoring systems without direct interaction, like network sniffing. Offensive testing is a broader category that includes penetration testing, but "physical" is a more specific and accurate description of the type of test being performed in this context.
