There has been lots of info already posted, but based on the fact you call yourself an "Enterprise Security Specialist" I hope you knew most of it, including the the limitations of SPAN ports v.s dedicated taps, and the different options such as inline devices, or passive etc :) In terms of what I think your specific question was (based on the subject of your email), you should look at like FreeBSD. They have been pretty cutting edge in terms of adding things like zero copy into the BPF libraries (http://en.wikipedia.org/wiki/Berkeley_Packet_Filter). i.e. they take packet capture seriously. Before putting anything inline, sniffing for a while to see what's actually being used before you start blocking isn't a bad idea. It will not actually take you very long to find out what other than web is exiting your gateway. Al @Jonathon Leigh - I've never seen any Cisco device that can log every packet> But all the Cisco kit I work with can do SPAN (most can do RSPAN too) which you could use to feed into your sniffer.

Hello, I'm new to this mail list so lets first introduce myself - my name is Hristiyan Lazarov and I'm currently working as an Enterprise Security Specialist for a UK based company. I'm looking to implement in our organisation *NIX based network sniffer. Basically, I want to trace and record every single packet that is coming to, or going out from my network. We are working with sensitive information, that's why my employer want me to record the traffic at least 1 month back. We have a proxy which is dealing with our HTTP traffic but some people are playing smart trying to use some anonymizers to access restricted websites. Any suggestions would be greatly appreciated. ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
