AW: SQL injection

["Julian Totzek" <julian.totzek () bristol de>]

Hi Faisal,

take a look at imperva. They have a real good model with securing sql databases. We advise this product if there is the 
special need for a customer to secure his sql databases.

If you say you are using Toplayer, I don't know which one you have but the new models (IPS5500 series) also have the 
ability to mitigate sql injections by pattern! But as my previous speakers the mitigation of sql injections is a hard 
thing to do by pattern.
