Chan, Look into switch configurations. I think you can setup the switch so that you can moniter traffic in A way that won't slow things down.

Lets say I have a scenario where all the servers in DMZ that are connected to a gigabit switch. The GE switch is connected to a Firewall GE port. I want to monitor the traffic between goes to the DMZ. So placing a GE NS7.0 will be the solutions. But, I'm not sure how the deployment will be. First, I don't think Port mirror a GE switch will work since the traffic will be extremely high. Placing a HUB between the Firewall and GE switch won't solve the issue also because the I don't think the HUB can handle so huge traffic flows. So, the other solution that I can think of is to use the GE network Taps to taps the traffic. Now the questions, if using Taps, is that mean need to have 2 GE NIC on the NS for monitoring the TX and RX, I 100Mbs NIC to connect to the secure LAN where the console is and 1 more GE NIC to send the kill. Will this idea work? May be some of u guy has better idea? Thanks.... ******************************************* Chan Kien Eng Security Consultant Evolution Security Solutions Sdn.
