One of my favorite online publications is (In)Secure Magazine - it's a PDF-formatted online magazine that comes out a few times a year. It's always full of interesting articles, and never more so than the new issue, 1.10. It features an interview with Joanna Rutkowska (who is speaking at SecTor... check out her blog, you should), as well as an article written by me on building a career in information security.
The article is a general overview targeted more at the junior security pro, but I hope is interesting even to the most seasoned security expert out there.
Drop by (In)SecureMag.com and pick up a copy. It's a good read.
