Leo and I discuss the week's major security events and discuss questions and comments from listeners of previous episodes. We tie up loose ends, explore a wide range of topics that are too small to fill their own episode, clarify any confusion from previous installments, and present real world 'application notes' for any of the security technologies and issues we have previously discussed.

Leo and I discuss the role, importance and operation of cryptographically-keyed message digest algorithms and their use to securely authenticate messages: Hashed Messages Authentication Codes.

Before tackling the complete description of the operation of the SSL (Secure Socket Layer) protocol, this week Leo and I take a step back to survey and review much of the cryptographic material we have covered during past 3+ years of podcasts.

Steve and Leo delve into the detailed inner workings of security certificates upon which the Internet depends for establishing the identity of users, websites, and other remote entities. After establishing how certificates perform these functions, Steve describes how a team of security researchers successfully cracked this "uncrackable" security to create fraudulent identifications.

Leo and I discuss the newly discovered cracks in SSL (Secure Sockets Layer), Antique PDP-8 minicomputers, a new PDP-8 kit you can build, and the importance of next generation UltraCapacitors.

Leo and I delve into the inner workings of a free, easy to use and useful yet unknown Microsoft utility known as "DropMyRights." It can be used to easily run selected, dangerous Internet-facing applications - such as your web browser and email client - under reduced, safer non-administrative privileges while everything else in the system runs unhampered.

Leo and I return to take a much closer look at "Sandboxie," an extremely useful, powerful, and highly recommended Windows security tool we first mentioned two years ago. This time, after interviewing Sandboxie's creator, Ronen Tzur, I explain why I am totally hooked and why Leo is wishing it was available for his Macs.

Leo and I begin with a refresher on WEP, the original technology of WiFi encryption. With that fresh background, we then tackle the detailed explanation of every aspect of the recently revealed very clever hack against the TKIP security protocol. TKIP is the older and less secure of the two security protocols offered within the WPA and WPA2 WiFi Alliance certification standards.

Leo and I discuss yet another challenge to surfing safely in the web world: Known as "ClickJacking," or more formally as "UI Redressing," this class of newly popular threats tricks web users into performing web-based actions they don't intend by leading them to believe they are doing something else entirely.

Leo and I discuss a class of newly disclosed vulnerabilities reported to exist in many operating systems' implementations of the fundamental TCP protocol. Two security researchers, claiming that they could not get anyone's attention (after less than one month), disclosed far too much information in a recent audio interview — leaving little to the imagination — and exposing the Internet to a new cl...

Leo and I wrap up the loose ends from last week's final Q&A question regarding the self-removal of the GoogleUpdate system following the removal of Google's Chrome web browser, then we discuss the operation and politics of upgrading the Internet's entire DNS system to fully secure operation.
