CompTIA Security+ SY0-701 Practice Question

Refining the correlation rules to establish more stringent alert criteria can significantly decrease the amount of false positive alerts generated by a Security Information and Event Management system. By defining more precise conditions for when an alert should be triggered, a SIEM can more accurately differentiate between standard operations and suspicious activities. Adjustments must be crafted carefully to minimize the risk of missing true security incidents. Altering system thresholds indiscriminately might suppress important warnings, while focus solely on historical data analysis may not take into account novel or evolving threats. Disabling alerts for activities that are considered to be low risk can be risky, as they might cumulatively indicate a security threat if analyzed in context.
