If you're not familiar with the wonderful audio podcast series that Steve Gibson and Leo LaPorte have named "Security Now!", then you're really missing out, and you should go and check it out at http://www.grc.com/securitynow.htm.
If you're a "Security Now!" listener, then you
know how Steve and Leo explain the intricacies of the Internet, Local
Area Networks, (LANs), Wide Area Networks (WANs), Virtual Private
Networks (VPNs), and information security. We enjoy their podcast very much, but every
few weeks, Steve creates a complex, "Propeller-Head" episode that
really cries out for visualization through illustrations or animations.
Steve and Leo have been at this for a long time, with more than 300 shows. Among these gems are dozens and dozens of
That's why we created this section.
Episode by episode, we are working through every Security Now!
podcast to identify the rich, complex programs in which Steve reveals
the inner workings of something amazing. Then, for each of these
special podcast episodes, we are creating a corresponding set of
"Security Now Illustrated" video clips with rich, beautiful
illustrations and animations to illuminate and portray Steve's deep
dialog. (And please continue to support Steve and Leo and their
products and sponsors through their websites. We can't cover them all
here, and many of the old episodes "in between" those we illustrate
include additional, important details.)
This is a free,
advertising-sponsored site, and the ads pay for our
efforts. We work hard to attract advertisers that add value to your
experience, and also to make sure that our advertisers are treated
fairly. If you see an advertisement here that is of genuine interest to
you, we hope you will explore it. On the other hand, please do NOT
click on ads that are not relevant to your interests or to the subject
at hand. The search engine at the top of this page is like a
regular Google search, but (because Google knows about the Security
Now! audience), the results are slightly skewed toward your interests,
and Google sends us a little bit of ad money when you use it. THANK YOU!
