How to intercept data on Internet? This can be done using number of technologies:

  • Winsock LSP – Is good when you want to operate at user level and inspect streams and not packets.
  • TDI – Soon to be phased out, it’s a driver like technology that can be used either in packet or stream level.
  • NDIS – Kernel driver that inspects packets and has total control over the network.
  • WFP – Microsoft new filterting platform, but until Windows XP is phased out, I forsee it will not gain momentum.

Windows Filtering Platform (WFP)

Thursday, March 18th, 2010

Windows Filtering Platform is a relativly new technology from Microsoft that was built to replace all existing technologies: Winsock LSP, TDI, NDIS.

First step would we TDI as Microsoft announced it will not be supported anymore on the next OS, but it seems that NDIS and LSP are supported.

I had a prospect ask me why I don’t WFP, well WFP the main reason not to use WFP for me is the lack of support for Windows XP (many of my clients also want to support Windows 2000), and until Windows XP will become obsolete, WFP will not gain momentum.
