December's Hackin9 magazine has been published on their website as a free download. The issue is completely about Snort!
We'd like to thank hackin9 magazine for putting out this issue. They got in touch with us here at Sourcefire and we contributed a couple articles for the issue, but they also reached out to the Snort community as well, which is always good, and the majority of the content is written by you, the community.
