SOC Analyst · Lesson 8 of 8
Closing an alert responsibly
Closing an alert is a documented decision. It is not proof that every related risk has disappeared.
Choose the next step from the evidence
Review this alert against the approved playbook
- Expected activity verifiedDocument and close
Record the matching test, entity, time window, and reason.
- Unexplained or concerning activityInvestigate or escalate
Preserve evidence and name the next owner.
Read the visualAn approved test explains another account. Can it close this alert?
No. The explanation must match the activity being reviewed.
Use a supported disposition
Explain whether evidence supports expected activity, a false alarm, or an incident referral. Use your team definitions.
Record remaining work
Track unresolved questions and remediation separately. A ticket assigned to someone is not a completed fix.
Improve the process
Suggest rule changes with examples and review. Broadly disabling detection to reduce noise can hide future incidents.
Put it in context
A scheduled test explains one alert. You document the approved test and exact time window, while leaving unrelated alerts open for their own review.
Close the specific case with evidence and preserve follow-up work.
Read the sources
Make it stick.
