I was off reading some older articles written on a couple of blogs that I follow looking for something in particular. Well, I never did find what i was looking for (in regards to the article itself), but I did reread this post by Jason Brvenik over at Snort.org.
This is a great article in response to another article about why small business shouldn't invest in IPS (which is a crazy view). Jason really does a nice job of laying out the reasons why its important. Definitely worth the read, or reread if you've seen it before.
