During a walk-through, an IS auditor observes an AI engineer entering a prompt that manipulates...

The most direct and effective control for preventing prompt-based manipulation is to enforce a structured input/output template (option A). AAIA highlights prompt management as a key emerging control area because unstructured prompts can lead to:

Prompt injection

Model manipulation

Circumvention of rules

Unauthorized access to sensitive outputs

Safety violations

Templates constrain user input to predefined formats, reducing opportunities to embed hidden instructions or modify model behavior.

Adversarial training (B) strengthens robustness but does not prevent users from inserting manipulative prompts.

Encryption (C) protects data, not prompt integrity.

Immediate retraining (D) addresses performance, not misuse.

Templates ensure consistent, secure, and auditable prompt structure.
