Which of the following is NOT a common type of security measure?

Medical response training is not typically categorized as a common type of security measure in the same context as access control, surveillance systems, and physical barriers.

Access control refers to the methods used to regulate who can enter a particular area or access specific information, enhancing overall security. Surveillance systems, such as cameras and monitoring technologies, are crucial for observation and can aid in the deterrence of unlawful activities. Physical barriers, like fences and gates, serve to protect a facility by preventing unauthorized access and ensuring that only designated individuals can enter.

Conversely, medical response training is focused on preparedness for medical emergencies and does not directly relate to protecting facilities or securing areas against threats. While vital for overall safety, it falls under emergency response rather than security measures aimed at preventing unauthorized access or ensuring surveillance.
