CompTIA CloudNetX CNX-001 Question # 12 Topic 2 Discussion

Comprehensive and Detailed Explanation From Exact Extract:

PF_RING is a high-performance packet capture and filtering framework that allows IDS systems to handle large volumes of traffic efficiently. By offloading and filtering out traffic that is known and trusted (such as HTTPS traffic from a patch server), the IDS can focus on analyzing critical traffic and reduce dropped packets.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Traffic Filtering and IDS Performance Optimization”:

“Advanced filtering solutions like PF_RING allow offloading of known trusted traffic, reducing processing overhead on IDS systems and improving visibility into meaningful events.”

Other options:

A. Directly configuring the IDS to ignore traffic may bypass too much, affecting visibility.

C. BPF filters on the tap itself may interfere with other systems using the tap.

D. Disabling the IDS temporarily removes all visibility — a poor security practice.
