How can the Brute Force Access Behavior Detected correlation search be made less sensitive?

The most effective way to make the Brute Force Access Behavior Detected correlation search less sensitive is to edit the search and alter the threshold value. This threshold determines how many failed login attempts must occur within a specified time frame before an alert is triggered. By increasing this threshold, you reduce the number of events that will activate the correlation search, which means you are requiring more failed login attempts for an alert to be generated. This adjustment allows for a more tailored approach to detecting brute force attacks, minimizing false positives that may arise from legitimate, albeit failed, login attempts.

Adjusting the search interval could result in fewer alerts due to the extended timeframe, but it does not fundamentally change how sensitivity is defined within the correlation search parameters. Changing the alert action to notify less frequently would reduce noise but would not prevent alerts from triggering; it only influences the frequency of notifications rather than the sensitivity of the event detection. Disabling the correlation search would stop it entirely, which is not a practical solution for maintaining security oversight and poses a risk of missing actual brute force attempts. Thus, modifying the threshold value is a targeted way to control the sensitivity of the detection.
