RE: Linux or Unix distribution for network sniffing

[Elliot van Gisteren <evangisteren () ssi-solutions com>]

Get a switch that can mirror ports, mirror the port going to out of your network (gateway port) and throw a traffic 
sniffer on it (wireshark, tcpdump) and constantly log, if you really want.  But really this is no complete solution.  
What you really want to do is lock down your network via outbound (from internal) ACLs and user restrictions on the 
workstations themselves (limit OS functionality).   If the employee's can't be trusted then take away their luxuries 
until they fall in line.

Subject: Linux or Unix distribution for network sniffing

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.
