A SOC deploys an AI assistant that summarises and prioritises incoming alerts to speed up triage. During a busy shift, an analyst notices the assistant consistently ranks alerts from one noisy scanner as top priority while burying a credential-stuffing pattern lower down. What is the analyst's best response?

  • AApply analyst judgement to re-prioritise the credential-stuffing alerts and report the ranking flaw for tuning. Correct
  • BDisable all AI triage assistance permanently, as it has proven unable to prioritise alerts correctly.
  • CContinue to accept the assistant's ranking, since the tool processes more context than a human analyst can.
  • DDelete the noisy scanner alerts from the queue so the assistant stops ranking them highly.
AI triage augments rather than replaces analyst judgement, so analysts override flawed prioritisation and feed corrections back for tuning. Alert triage augmentation is designed to assist human decisions, not overrule them, so when the tool mis-ranks a genuine threat the analyst reprioritises on the evidence and reports the flaw so the model can be tuned.

Why A is correct: Correct: AI triage augments the analyst, so the analyst overrides the flawed ranking on the evidence and feeds the issue back so the tool improves.

Why B is wrong: Tempting after a visible miss, but a single prioritisation error does not justify removing a tool that reduces overall triage load; the fix is oversight, not abandonment.

Why C is wrong: Tempting because AI can weigh more signals, but blind acceptance of a demonstrably skewed ranking lets a real threat sit unactioned.

Why D is wrong: Tempting as a quick way to clean the queue, but deleting source alerts destroys evidence and does not address the assistant's flawed weighting.
