Hi All, I am using snort version 2.8.5.1 and trying to understand how it works. I posted the same query earlier but did not get enough response. I am simulating attack packets using tool called snot. This tool generates attack packets which are basically stateless in nature. I mean it generates packets without proper 3 way TCP handshake. But snort is not detecting those attacks. I am able to see UDP, ICMP packets getting detected but not TCP. I read snort README and tried various options like require_3whs, detect anomalies etc in stream5 preprocessor with tcp_track set to yes but no luck. One response I got was snort latest version doesn't detect stateless attacks and expect the end host TCP stack will take care. But my concern what if the stack is not capable to handle such attack? Do we have any way by which we can tweak snort and detect such stateless attacks? Rgds, Sriharsha
