NSE7 Advanced Threat Protection Practice Question
An administrator runs 'diagnose ips anomaly list' and sees many 'data_leak' events from a specific internal IP address. The IPS sensor has the default pre-defined signatures enabled. What additional step should the administrator take to block this specific anomaly?
⚠ Common exam trap
Watch out — candidates often confuse 'anomaly events' with 'pre-defined signatures', assuming they can simply enable or block a signature by name, when in fact anomalies require custom signature creation to be blocked.
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
✓
Create a custom IPS signature to match the anomaly pattern and apply it to the IPS sensor
The 'diagnose ips anomaly list' command shows protocol anomaly events, which are detected by the IPS engine's built-in anomaly detection logic, not by pre-defined signatures. To block a specific anomaly pattern like 'data_leak', the administrator must create a custom IPS signature that matches the exact anomaly characteristics and apply it to the IPS sensor. Pre-defined signatures cannot be modified to block anomalies; only custom signatures can target these events.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable protocol anomaly detection in the antivirus profile
Why it's wrong here
Protocol anomaly detection is part of IPS, not antivirus.
- ✓
Create a custom IPS signature to match the anomaly pattern and apply it to the IPS sensor
Why this is correct
Custom signatures allow precise detection of protocol anomalies beyond pre-defined signatures.
- ✗
Enable the 'data_leak' signature in the IPS sensor and set action to 'block'
Why it's wrong here
Pre-defined signatures may not include 'data_leak' as a signature; anomalies are handled separately.
- ✗
Configure a firewall policy with application control to block the traffic
Why it's wrong here
Application control may not detect protocol anomalies; IPS is the correct tool.
