I should note that I didn't mean to imply that the rules using "flags:
AP;" were useless - just that they were too specific and could be easily
evaded by skilled attackers. As most of your know, there is a tight
shortage of skilled attackers so this change has minimal (but necessary)
There are no longer any tcp rules in arachNIDS that flag for the specific
PSH+ACK flags. I can't think of any attack where these flags (and only
these flags) must be present. All appication level attacks that fit into
this category that I can think of can be supplemented by extra flags to
I also wanted to clarify (correct me if you know otherwise) that by
broadening the tcp flags search we are not going to slow down Snort.
