What are the three categories included in the Detect (DE) function of the NIST Cybersecurity Framework?

The Detect (DE) function of the NIST Cybersecurity Framework emphasizes the importance of identifying potential cybersecurity events promptly and effectively. The accurate categories that fall under this function focus on actively monitoring and analyzing information to identify anomalies and respond to potential incidents.

The terms "analysis," "observation," and "detection" align well with the Detect function's purpose. Analysis refers to the examination of data collected from various sources to look for signs of compromised security. Observation involves ongoing monitoring of systems, networks, and activity logs to catch unusual or suspicious behavior. Detection is the actual identification of incidents or breaches based on the analysis and observation performed.

In contrast, the other options do not appropriately represent the Detect function's focus. Prevention, reaction, and assessment are more aligned with proactive and reactive measures rather than the core components of detection. Identification, mitigation, and reporting also straddle various functions and do not succinctly capture the essence of detection activities. Lastly, authentication, verification, and authorization relate more to access controls and identity management rather than directly to the detection of cybersecurity events.
