I understand that CSA is a behavior based HIDS. But what I would like to do, if possible, is supplement its policies with network layer signatures for monitoring purposes. Basically I would like to identify known exploit attempts.
Not quite what I'm looking for. I know I can do what you mentioned aboved, but I want to do something extra. For example, I want to monitor for WMF Buffer Overflows. I can't just monitor every JPG ever accessed, and even so I wouldn't get what IP triggered it. So I would like my user to be able to visit a web page, and perhaps on that web page is a bad image, and I would like to trigger an event based on the return traffic (the browser receiving the image that is trying to run the exploit) that tells me the image file name and site's IP address.
