What type of security involves the physical presence of personnel?

The correct answer is human security, which refers to the protection and safety measures provided by individuals who are present on-site. This type of security relies on trained personnel to monitor and respond to various situations, such as intrusions, emergencies, and other security breaches. Human security is effective because it includes the ability to assess situations in real time, communicate effectively, and react to threats with judgment and intuition that automated systems do not possess.

In contrast, electronic security involves the use of technology such as alarms, cameras, and access control systems, which do not provide the physical presence of personnel. Remote security typically refers to surveillance and monitoring conducted from a distance, often through the use of electronic devices, and also lacks the immediate human response that personnel provide. Data security focuses on protecting information, particularly in digital formats, which does not involve personnel presence in a physical sense. All of these options emphasize different aspects of security, but human security distinctly highlights the importance of having trained individuals present to ensure safety and security.
