AI Incident Response — Assess: Scope, Severity, and Response Tier
This episode of the ISACA Advanced in AI Audit (AAIA) exam prep series covers Phase 3 — Assess, the investigative step that sits between detection and active response in the five-phase incident-response lifecycle. You’ll see how teams systematically gather facts, size up the extent of a problem, and protect the evidence trail when an intelligent system goes wrong. The discussion gives auditors a structured way to measure damage and meet legal obligations without rushing decisions that reopen the wound.
What this episode covers
- The lead detective mindset — switching from operational thinking to evidence-driven investigation.
- Three core elements — establishing timeline, scope, and impact of the AI incident.
- Balancing speed with evidence integrity — moving fast without destroying the digital breadcrumbs.
- Leaning on system documentation — using the model map to spot anomalies quickly and safely.
- Diagnostic questions on containment and verified facts — separating active damage from rumors.
- Discovery time and breach notification requirements — why the discovery timestamp drives legal deadlines.
- Step-by-step details and compromised assets — mapping affected databases, modules, algorithms, and attacker tactics.
- Identifying blind spots — naming what you still need to learn before safely reactivating systems.
Watch the full episode above for the worked examples and detailed explanations of each concept.
Frequently Asked Questions
What are the three core elements to establish during the assess phase?
You must establish the timeline, the scope, and the impact of the event. The timeline dictates when the issue began and how it progressed, the scope defines the boundaries of the problem by showing how many systems or users were touched, and the impact measures the actual damage or negative consequences that resulted from the failure.
How do you balance speed with evidence preservation during assessment?
Speed is critical, but you must gather facts rapidly without compromising the integrity of the investigation. Compromising integrity means accidentally deleting logs, altering system states, or destroying the digital breadcrumbs that reveal what caused the malfunction. Relying on system documentation, which maps how the model was built and should function, lets you zero in on anomalies faster without destroying critical evidence.
Why does the moment an AI incident was discovered matter so much?
Determining the exact moment the problem was first discovered is crucial because of breach notification requirements. These are strict legal rules that force organizations to inform regulators and the public about a security incident within a specific number of hours or days after discovery, so the discovery timestamp directly drives your legal reporting deadlines.
What diagnostic questions should you answer during the assess phase?
Ask whether the malfunction is contained or still causing damage, separate verified facts from rumors, identify who was harmed and how, pin down when the problem was discovered for breach notification, document the step-by-step details of what happened, map which databases, modules and algorithms were compromised, determine what tactics an attacker used, and clearly identify your blind spots and what you must learn before safely turning systems back on.
