Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Signature-based detection
Why this is correct
Signature-based detection matches traffic against known attack patterns.
- ✗
Behavioral detection
Why it's wrong here
Behavioral detection is a subset of anomaly-based detection.
- ✗
Heuristic detection
Why it's wrong here
Heuristic detection uses algorithms to identify suspicious behavior, not fixed signatures.
- ✗
Anomaly-based detection
Why it's wrong here
Anomaly-based detection uses baselines of normal behavior, not specific patterns.
