Not for nothing but #2 is exactly what Sourcefire's been doing since 2004. Sorry for the commercial but I think I've been pretty outspoken on this topic since 2000 or so...Well, I guess I have to pipe in also, then. Cisco is doing the same. Read my book "Security Monitoring with CS-MARS" for more info.Sorry Marty, sorry Gary, I love both products, but they are not even close to realizing what Greg asked for :) Of course, they do reduce "false positives/noncontextual alerts/whatevers", and so they are to be commended, but knowing "if the attack has been successful" is actually way beyond anybody's capability, short of a crystal sphere
agree 100%. my impression of these tools is that they mostly reduce the low-hanging "false positives", hopefully allowing the analyst to focus on the stuff that can't be pruned by the "expert system". the cross device correlation can provide nice supporting data (or totally irrelevant in some cases) but there is usually one event that *might* be significant...the potential, but probably not, "smoking gun" as it were;-) Attacks are moving up the stack. They're also targeting clients more. Both trends introduce a ton of challenges for getting relevant context. I can't help but wonder if/how these tools will be able to get the context they need to keep up with relevant threats. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ----------------------------------------------------------------- Securing Your Online Data Transfer with SSL.
