We have been using signature-based systems but now feel the need for some additional security protection that might be provided via an anomaly-based IDS system (zero day exploits, etc).
I'm not experienced with anomaly-based systems and know only what I've seen on the web, or sevral years ago at some trade shows. Some seem to be focused more on network operation but also have the IDS component. At least for right now, I've been asked to look at security systems. Any good ideas, suggestions, or horror stories about anomaly-based systems that may be a help would be appreciated. Up til now I've only been saving signature related emails from this list.

Using PL/SQL I can write same query with different ways and different constructs that leads to different query patterns. So does not that mean stateless signature based IDS/IPS are useless for database servers, etc. Best Regards, Mayur ------------------------------------------------------------------------ Test Your IDS Is your IDS deployed correctly?
