What is the primary function of the "DE" in the NIST Cybersecurity Framework?

The "DE" in the NIST Cybersecurity Framework refers to the "Detect" function. This function is designed to identify and detect cybersecurity events in a timely manner. The primary goal of the Detect function is to ensure that organizations can recognize when a cybersecurity incident occurs or is about to occur, enabling them to respond effectively.

The Detect function consists of activities that help establish and maintain the capability to identify potential security incidents. This involves using security monitoring processes, intrusion detection systems, and continuous network monitoring to gauge the security posture of the organization. By focusing on detection, organizations can leverage tools and processes to alert them to anomalies and potential threats, which is crucial for the effective management of cyber risks.

In the context of the NIST framework, prioritizing detection is essential because it aids in incident response planning and management, allowing for quicker remediation of threats, ultimately preventing potential greater losses.
