What is the action required for reviewing and filtering alerts?

Triage is the appropriate action for reviewing and filtering alerts. This process involves evaluating the alerts to prioritize them based on their severity and potential impact. Triage allows security personnel to determine which alerts require immediate attention, which can be investigated further, and which may be relatively benign or false positives.

In the context of security operations, effectively triaging alerts is critical for efficient incident response. It helps organizations manage resources more effectively by focusing on the most critical threats first, ensuring that any real incidents can be addressed promptly before they escalate. This systematic approach to alert management is foundational in maintaining an effective security posture.

Investigating alerts refers to the deeper analysis required once an alert has been triaged and deemed significant. While action might suggest a proactive step in responding to a confirmed issue, it doesn't specifically apply to the initial filtering and prioritization phase, which is where triage plays its crucial role. Managing alerts could imply a broader range of activities, including triaging, but does not solely capture the essential first step of focused review and filtering that triage embodies.
