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 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 class of DoS attacks. They'll certainly get attention now. (See this episode's Show Notes for many additional links.)

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.

Leo and I examine Google's new "Chrome" web browser. Leo likes Chrome and attempts to defend it as being just a beta release; but, while I am impressed by the possibilities created by Chrome's underlying architecture, I'm extremely unimpressed by its total lack of critically important security and privacy features.

Steve and Leo discuss some recent revelations made by two talented security researchers during their presentation at the Black Hat conference. Steve explains how, why, and where the much touted security improvements introduced in the Windows Vista operating system fail to prevent the exploitation of unknown security vulnerabilities.

Leo and I follow-up on the recent industry-wide events surrounding the discovery, partial repair, and disclosure of the serious (and still somewhat present) "spoofability flaw" in the Internet's DNS protocol. We also examine what more can be done to make DNS less spoofable.
