A network TAP is a hardware or virtual mechanism that passively copies network traffic for monitoring or analysis without sitting inline in the traffic path. It matters because security visibility improves when monitoring systems can observe traffic without becoming a point of forwarding dependency.
What is Network TAP?
TAPs are often used for IDS, network forensics, packet capture, and security analytics. Because they passively duplicate traffic, they can provide reliable visibility with less risk of affecting production flow directly.
What Network TAP Commonly Supports
Common uses include IDS monitoring, packet capture, traffic analysis, network forensics, and visibility architecture.
Network TAP vs. Inline Inspection Device
A TAP passively copies traffic. Inline devices actively sit in the path and can enforce, modify, or block traffic.
Frequently Asked Questions
Why use a TAP?
Because it can provide rich network visibility without becoming a forwarding choke point for the original traffic.
Is a TAP the same as port mirroring?
No. They are related visibility methods, but TAPs and mirrored switch ports differ in architecture and reliability characteristics.
