There are now quite a number of podcasts available, covering all areas of Information Security - I find it a great way to stay up to date with the industry news, particularly when commuting. A fairly comprehensive list can be found at http://getmon.com/, while my current regular favorites are below:

• Paul Dot Com Security Weekly (feed) - one of the longest established US based security podcasts, normally around 2 hours long, with interviews, technical segments and industry news.
• Risky Business (feed) - an Australian based ~30 minute show, neatly split into news, interview and sponsor interview
• 2600 | Off The Hook (feed) - airs every Wednesday night at 7:00 PM EST in New York City on listener supported WBAI 99.5 FM.

I've created an aggregated feed of my Podroll, which makes subscribing quick and simple - on my phone, it means adding just one feed, instead of lots of different feeds for different podcasts (very useful when rebuilding your phone after flashing the latest ROM)... I did try RSSmix.com, which IronGeek also uses, but I found updates through the site don't seem to be that regular (and the site itself can run pretty slow as well), which means missing out on the latest content. Instead, I use Yahoo Pipes to merge and manipulate the various feeds together, and then publish through Feedburner to get some extra control / statistics.

You can subscribe to my Podroll feed here (http://feeds.andrewallen.co.uk/andrewallen/podroll), or you can view the Yahoo Pipes source here.

Update - Dec 14

I've updated the pipe to include the following feeds, and also strip posts with no enclosures:

• RB2 (feed)
• Network Security Podcast (feed)
• Security Justice (feed)
• Securabit (feed)
• Tenable Network Security Podcast (feed)
