American Airlines

I wound up flying First Class in American Airlines today. Let me just compliment AA. Best two flights I have ever had. Aside from being late out of ATL (which was ATL's fault, I am sure), I sat in first class, I got a meal, (vegetable pizza and a salad. it was good!), and aside from the lady who had a panic attack on the plane and had to be given oxygen.

American Airlines rox. I'd fly American Airlines if I could everytime if their service was that good every time.

Offset, Depth, Distance, and Within

Without going off the deep-end here and discussing every single Snort rule keyword, I just wanted to touch on a few modifiers that people sometimes misunderstand. They aren't difficult, and hopefully after this explanation and a few examples, I can clear some of the air around these five modifiers.

The five modifiers that I am talking about are
OffsetDepthDistanceWithinnocaseThese five modifiers are not keywords of themselves, but rather they apply as modifiers to another keyword. That keyword is "content". The content keyword is one of the easiest pieces of the Snort rules language as all it does is look for a particular string. So for instance if I wanted to look for the word "joel" within a packet.

It's great when people in the Snort community step up and explain some simple things out there. There are mistakes, it comes with the territory. If you choose to be one of the people that tries to write Snort rules, you also choose to be someone who wants to learn how to do it better. That's why I write this blog post, not to bash the writer, but to teach.

I noticed this post today over at the "Tao of Signature Writing" blog, and to be honest I glanced over most of it figuring it was a rehash of things I've already read or things that have already been written from countless people about "Here's how you write Snort rules!". I scrolled down quickly skimming, not reading at all really, and noticed this part:
