Create a custom signature to rate limit (packet/sec) on IPS 4200?

Hello everyone,

There's a lot of public and simple tool to flood attack a host with TCP, UDP packet. These tools can send TCP/UDP packet very fast and quickly bring down weak network devices & servers.

We are going to public a website and i'm worry about risk of attacking. I put IPS 4260 in DMZ to protect server. When I turn on default signature, it can not prevent DoS flood attack.

So could you please help to me create a custom signature that can check packet per second? For example, if there are more than 10 pps, IPS must deny attacker inline or something... I have tried to make a custom signature based on Flood Net engine, set the rate, gap, but I dont really understand these parameters and it does not work.

Please guide me something to do that. Thank you very much.
