Changing reporting thresholds is the best method to optimize the monitoring process when the automated security monitoring tool generates an excessively large amount of false positives. Changing reporting thresholds means adjusting the criteria or parameters that trigger the alerts, such as the severity level, the frequency, the source, or the destination of the events. Changing reporting thresholds can help to reduce the number of false positives, filter out the irrelevant or benign events, and focus on the most critical and suspicious events that require further investigation or response.
