AI Audit Scoping
Scoping determines which AI systems, data, models, business processes, vendors, controls, time periods, users, and risks are included or excluded.
How to study for ISACA AAIA
Treat each item as an audit decision: understand AI risk, identify criteria, test evidence, assess control effectiveness, then report impact and follow-up.
Core concepts
Concept 1
AI audit scope should cover the systems, models, data, prompts, tools, integrations, vendors, controls, and processes relevant to the objective.
Exam cue: Include upstream data and downstream use when they affect AI risk.
Concept 2
Scope boundaries should be justified by risk, materiality, regulatory importance, business criticality, and assurance needs.
Exam cue: Document why any model, vendor, process, or control is excluded.
Concept 3
Auditors should document exclusions, dependencies, limitations, and assumptions that affect audit conclusions.
Exam cue: Adjust scope if discovery reveals material AI dependencies.
Risk pitfalls and guardrails
Scoping only the visible application and missing data pipelines or vendors.
Guardrail: Avoid treating AI audit as only a technical scan, accepting management assertions without evidence, or omitting prompts, data, vendors, and monitoring.
Excluding high-risk AI components for convenience.
Guardrail: Avoid treating AI audit as only a technical scan, accepting management assertions without evidence, or omitting prompts, data, vendors, and monitoring.
Failing to disclose scope limitations in the report.

Memory anchors
Scope Boundary
A scope boundary defines what AI systems, data, controls, periods, and processes are included or excluded.
Materiality
Materiality weighs whether an AI risk or control could affect decisions, operations, compliance, or users.
Dependency
A dependency is a data source, model, provider, tool, API, or process the AI system relies on.
Scope Limitation
A scope limitation restricts what auditors can test or conclude.
Exclusion Rationale
An exclusion rationale explains why an AI component or risk is outside the audit scope.
Process Boundary
A process boundary identifies where the audited AI-enabled workflow begins and ends.
Risk Coverage
Risk coverage checks whether the scope addresses the most significant AI risks.
Scope Change
A scope change updates audit coverage when new material facts emerge.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
