Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TCP handshake stateful inspection
Why it's wrong here
TCP stateful inspection occurs at Layer 4 (firewalls), whereas WAFs operate at Layer 7.
- ✗
Behavioral anomaly machine learning baseline profiling
Why it's wrong here
Behavioral profiling looks for deviations from established normal traffic baselines over time, not static known attack strings.
- ✗
Data Loss Prevention (DLP) pattern matching
Why it's wrong here
DLP focuses on outbound data leaks of sensitive info like credit cards, not inbound attack payloads.
- ✓
Signature-based detection rules
Why this is correct
Signature-based rules compare incoming request components against known malicious patterns and signatures.
