What should a security analyst consider when comparing inline traffic interrogation with traffic tapping to determine which approach to use in the network?

A network TAP or SPAN port replicates traffic signals to a dedicated monitoring port without interfering with the live traffic stream, which is the defining characteristic of passive tapping. This out-of-band approach means tapping introduces no latency and cannot drop or block packets, but it provides full traffic visibility for forensic or compliance analysis. This fundamental difference is the primary consideration when choosing between tapping and inline deployment.

Tapping is an out-of-band passive technique and physically cannot block or drop malicious traffic because it only receives a copy of the data, not the live stream.

Viewing a copy of traffic describes tapping, not inline interrogation - inline devices sit directly in the live traffic path and process actual packets, not replicated copies.

Inline devices such as an IPS are capable of both detecting and actively blocking malicious traffic because all live packets pass through them before reaching the destination.
