It's a personal conviction of mine that, for how much of the tech industry operates out of Atlanta, there is a serious lack of quality security conferences and communities. But I know some people trying to change that.
The ISACA Atlanta Chapter is hosting 404con, a technical security conference, on October 14th and 15th, and they're looking for talk submissions for the hacking track.
