David Hoelzer, former lead for the Audit curriculum at SANS, records a weekly podcast with useful tips, techniques, audit demonstrations and other timely operational, audit and security related topics. Each episode is only about 10 minutes long, giving you a bite-sized tip that you can put into practice right after the podcast. Each episode also includes "Show Notes" that are linked from the podcast to the SANS Audit Blog. These contain any command lines, extra explanations, sample files, links to tools and scripts, etc. New episodes are released every Monday morning.
If you'd like to watch the episodes individually, you can find them at AuditCasts.com If you are an iTunes/iPad/iPhone/iPod user you can also subscribe to David Hoelzer's audit podcast via iTunes. To suggest episode topics, always feel free to submit them firstname.lastname@example.org.
