The security team at a large corporation is inundated with alerts from their Security Information and Event Management system, with a substantial number being false positives. What is the most effective approach to reduce the number of false positive alerts without significantly compromising the ability to detect actual threats?
Turn off alerts for events considered low risk to reduce the number of incoming notifications.
Refine correlation rules to enforce more specific conditions for triggering alerts.
Raise the alert threshold so only the highest severity incidents are reported.
Disable alerts that are commonly producing false positives.
