AI0-001 AI Security Practice Question
A company is training a model on proprietary data and wants to prevent data poisoning. Which TWO practices are most important? (Select TWO.)
⚠ Common exam trap
The AI0-001 exam often tests the distinction between security controls that prevent attacks (access controls, integrity validation) versus performance tuning (model size, epochs) or privacy techniques (homomorphic encryption), leading candidates to confuse data poisoning prevention with unrelated optimizations.

Correct answer & explanation
✓
Implementing access controls on the training dataset
Implementing access controls on the training dataset (Option A) is critical because it restricts who can read, modify, or delete the data, thereby preventing unauthorized actors from injecting malicious samples. This is a fundamental security measure to protect the integrity of the training pipeline against data poisoning attacks. Validating the integrity of training data (Option B) ensures that the data has not been tampered with, for example by using checksums or cryptographic hashes, which directly counters poisoning attempts that rely on corrupted input.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implementing access controls on the training dataset
Why this is correct
Access controls restrict who can modify the training data, reducing the risk of poisoning.
- ✓
Validating the integrity of training data
Why this is correct
Data validation detects anomalies or malicious modifications in the dataset.
- ✗
Using a larger model
Why it's wrong here
Model size does not prevent data poisoning.
- ✗
Increasing training epochs
Why it's wrong here
More epochs may cause overfitting but do not prevent poisoning.
- ✗
Using homomorphic encryption
Why it's wrong here
Homomorphic encryption protects data during computation but does not prevent poisoning of the dataset itself.
