ISC Risk Management Practice Question
You are evaluating the risk of an Artificial Intelligence (AI) model deployment. The model is susceptible to 'model inversion' attacks, where an attacker can reconstruct sensitive training data. What is the most effective engineering control to prevent this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply differential privacy techniques to the training process.
Differential privacy adds statistical noise to the training data or the model's output, preventing the reconstruction of individual training samples while maintaining the model's overall utility.
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 the model weights at rest.
Why it's wrong here
Weight encryption prevents unauthorized access to the model file, but it does not prevent attacks via the model's inference API.
- ✗
Implement rate limiting on the model's API.
Why it's wrong here
Rate limiting may slow down an attacker, but it does not prevent model inversion if the attacker has sufficient queries.
- ✗
Retrain the model on a smaller, obfuscated dataset.
Why it's wrong here
Reducing dataset size does not inherently prevent inversion and may decrease model performance.
- ✓
Apply differential privacy techniques to the training process.
Why this is correct
Differential privacy provides a mathematical guarantee against the reconstruction of individual data points.
