How do detective controls operate within a security framework?

Detective controls play a critical role in a security framework by focusing on identifying and alerting about ongoing or past security incidents. These controls are designed to detect and notify stakeholders when security breaches or anomalies occur, enabling timely responses to mitigate risks. For example, intrusion detection systems (IDS), security information and event management (SIEM) solutions, and log monitoring tools are common forms of detective controls. They continuously analyze system activities and traffic patterns to flag suspicious behavior and help organizations respond quickly to potential threats.

It's important to understand that while preventive controls aim to stop unauthorized access, block malware, or strengthen credentials, detective controls specifically deal with detection and monitoring activities. Their primary function is not to prevent incidents before they happen but to provide visibility and understanding of security events as they unfold or have already occurred. This detection capability is essential for effective incident response and minimizing overall risk within an organization.
