CND Practice Question: Network Security Controls Protocols And Devices
A security engineer is configuring a Next-Generation Firewall (NGFW) to perform deep packet inspection (DPI) on encrypted TLS traffic. Due to privacy regulations, specific internal banking applications must be excluded from SSL decryption. How should the engineer configure the firewall to bypass decryption for these specific destinations without disabling overall inspection?
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
✓
Configure a Decryption Exclusion / Bypass rule for specific trusted destination URL categories or domains
NGFWs support SSL/TLS Decryption Exclusion (or SSL Decryption Profile exceptions) based on destination domain categories or specific URL lists, allowing traffic to pass encrypted while still applying Layer 7 application firewalls.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an outbound NAT rule mapping banking IP addresses to a loopback interface.
Why it's wrong here
NAT mapping alters IP addresses, but it does not selectively exempt specific destinations from SSL inspection profiles.
- ✗
Configure a static route directing banking traffic through an uninspected bypass interface.
Why it's wrong here
Routing traffic through a different interface does not provide granular decryption exclusion within the NGFW policy engine.
- ✓
Configure a Decryption Exclusion / Bypass rule for specific trusted destination URL categories or domains
Why this is correct
Decryption bypass lists permit specific sensitive domains to be excluded from SSL inspection while maintaining protection for other traffic.
- ✗
Disable all Layer 7 application inspection signatures globally for TCP port 443.
Why it's wrong here
Disabling Layer 7 inspection globally removes security visibility across all HTTPS traffic, which is insecure.
