A podcast can teach you the fundamentals of information security in small, easily digested weekly chunks. Security Now is a wonderful podcast from Leo Laporte and Steve Gibson, with a new episode every week. Gibson covers a number of high-level subjects — securing your traffic on WiFi networks, choosing good passwords, etc — as well as topical ones — understanding rootkits and worms — and answers listener questions.
The past two shows have marked the commencement of a new series on how the underlying infrastructure of the Internet works — what's IP, what's UDP, how do packets traverse the Internet, and so on. This is building a foundation for deepening understandings of Internet security issues.
All told, the show is a running master-class in infosec, a great primer for those of us hoping to deepen our understanding of security online.
