AI0-001 AI Security, Ethics and Governance Practice Question
A security analyst is reviewing logs from an AI-powered recommendation system and notices an unusually high number of requests for products from a specific vendor. The analyst suspects data poisoning. Which mitigation strategy should be implemented first?
⚠ Common exam trap
The AI0-001 exam often tests the principle of defense in depth by making candidates choose a reactive or recovery measure (like retraining or monitoring outputs) instead of the proactive control that stops the attack at the input stage.

Correct answer & explanation
✓
Implement input validation and sanitization for training data
Input validation and sanitization directly prevent malicious or anomalous data from entering the training pipeline, which is the root cause of data poisoning. In an AI-powered recommendation system, poisoned training data can cause the model to learn biased associations, such as favoring a specific vendor. By validating and sanitizing inputs before they are used for training, the attack vector is blocked at the earliest stage, making it the most effective first mitigation step.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Encrypt all training data at rest
Why it's wrong here
Encryption protects confidentiality, not integrity against poisoning.
- ✗
Deploy an anomaly detection system on model outputs
Why it's wrong here
Anomaly detection is reactive and does not prevent initial poisoning.
- ✗
Retrain the model with a smaller, curated dataset
Why it's wrong here
Retraining with curated data may help but is not the first step; validation is needed first.
- ✓
Implement input validation and sanitization for training data
Why this is correct
Input validation prevents poisoned data from entering the training pipeline.
