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.

✓
Signature-based detection
The rule uses a specific content pattern 'malicious' to match traffic, which is characteristic of signature-based detection. Signature-based IDS relies on predefined patterns or signatures to identify known threats.

- ✗
Behavioral detection
Why it's wrong here

- ✗
Heuristic detection
Why it's wrong here
Incorrect. Heuristic detection uses algorithms to detect suspicious behavior, not exact patterns.

Anomaly-based detection
Why it's wrong here
Incorrect. Anomaly-based detection uses baselines of normal behavior, not static patterns.
