SSCP Practice Question: A network administrator needs to ensure that…
A network administrator needs to ensure that internal users can access only approved external websites. Which technology should be implemented?
⚠ Common exam trap
ISC2 often tests the misconception that an IPS or firewall can perform URL filtering, but these devices typically filter based on IP/port/application signatures, not full URL paths or content categories, which is the specific function of a web proxy with content filtering.
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
✓
Web Proxy with content filtering
A web proxy with content filtering intercepts HTTP/HTTPS requests from internal users and applies policy rules (e.g., URL whitelists, category blocking) to allow only approved external websites. This technology operates at the application layer, inspecting the full URL and content, making it the correct choice for granular access control.
