CS0-003 Security Operations Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Escalate to a senior analyst

  Why it's wrong here

  Escalating a confirmed false positive to a senior analyst unnecessarily consumes tier-2 or tier-3 resources and contributes to alert fatigue. Tier-1 analysts should handle routine false positives by initiating standard tuning procedures rather than passing low-risk, non-threatening events up the chain of command. This ensures senior staff can focus on actual security incidents.

• ✗

  Disable the SIEM alert permanently

  Why it's wrong here

  Permanently disabling the SIEM alert is a dangerous action that creates significant visibility blind spots across the enterprise. While it stops the immediate false positive, it also prevents the SIEM from detecting legitimate, malicious activity that relies on the same trigger mechanism. Security teams must modify the alert's logic rather than silencing the detector entirely.

• ✓

  Tune the alert to suppress similar events

  Why this is correct

  Tuning the alert is the industry-standard method for managing false positives because it refines the detection logic to exclude benign, repetitive behavior. By adding specific exclusions, such as a trusted IP address or a known service account, the analyst reduces noise and alert fatigue without compromising the SIEM's ability to identify actual threats.

• ✗

  Create a correlation rule to link with other events

  Why it's wrong here

  Creating a correlation rule is designed to link disparate security events together to identify complex attack paths, not to suppress a single, known false positive. Attempting to use correlation rules for this purpose adds unnecessary complexity to the SIEM architecture and fails to address the underlying noise generated by the poorly calibrated single alert.
