There is probably an obvious answer to this, but if so it's eluding me at the moment. I see a lot of Snort events from a lot of customer networks from all over the world. Every once in a while I see syslog alerts that are different than I expect. I have a ton of regular expressions to filter things, and I get odd stuff that doesn't match. For example, I'm getting this one, note the missing src and dst ports (made up IPs): ...BAD-TRAFFIC bad frag bits [Classification: Misc activity] [Priority: 3]: {TCP} 172.16.52.75 -> 10.10.10.81 I'm expecting something like this: {TCP} 172.16.52.75:80 -> 10.10.10.81:3565 Off the top of my head, I don't even know how to do that on purpose! How do you change the output? I sometimes see missing ports, or missing punctuation here and there... What am I not considering here?
