Stoping SQL injection

[arnis]

Hi

I am looking into using an Cisco ACE module to filter http request, for possible SQL injection strings.

Do any of you have any examples of code from routers, firewalls or the ACE that does that i.e. filter SQL injection strings going to WEB servers ?

Cheers

Arni

The TCP port 1433 and UDP port 1434 are used for Structured Query Language (SQL) server traffic. A new worm targets the UDP port 1434 and attempts to exploit a buffer overflow vulnerability in Microsoft's SQL server.
