Microsoft's new TechNet Radio audio show is an informative way to learn about IT. Their first bradcast is called “IT Security at Microsoft,” and it covers a lot of ground. Worth the listen!

Learning about how other companies deal with network and information security, especially big ones like Microsoft, is a valuable exercise in developing your own IT security strategy. Microsoft has over 300,000 network devices, and more than 50,000 employees. They are pretty free-form in terms of allowing their employees to install software as needed, run beta and “dogfood” software in production, and have some interesting ways of dealing with the environment. Microsoft's similar to where I work in terms of culture and whatnot. I've had the opportunity to visit Redmend and to talk with people there on a regualr basis, but even so this broadcast was useful and made me think.
