Which security measure is a part of detective controls?

Surveillance cameras are a quintessential example of detective controls in a security framework. These devices are specifically designed to monitor activities and detect unauthorized access or unusual behavior. By capturing video footage, surveillance cameras help in identifying security breaches as they occur, as well as provide evidence for investigations after an incident. They enable organizations to respond quickly to potential threats and maintain a constant watch over their premises, thus enhancing overall security effectiveness.

In contrast, access control systems, security personnel, and physical barriers serve more direct roles in preventing unauthorized access and mitigating threats. Access control systems implement restrictions or authorizations to permit entry; security personnel actively monitor and manage security situations; and physical barriers such as fences or walls are physical obstacles designed to deter intruders. While these measures are essential components of a holistic security strategy, they primarily focus on prevention rather than detection, which is where surveillance cameras excel.
