What kind of events is anomaly-based detection concerned with?

Anomaly-based detection focuses on identifying activities that deviate from established norms or expected behaviors within a network. This form of detection involves monitoring and analyzing network traffic, user behavior, and system performance to establish a baseline of what is considered normal. Once this baseline is established, the system can identify when an event falls outside of this normal behavior, which is characterized as abnormal activity.

The detection of such activities is crucial for identifying potential security threats that may not match existing signatures or known indicators of compromise, thereby enabling proactive responses to incidents that could compromise network security.
