Leo and I get a bit philosophical this week. We discuss the broad nature of Security — all security, not just computer security. We propose a new definition of 'Security' and flesh it out with examples to illustrate why security is so difficult, if not impossible.

Leo and I discuss questions asked by listeners of our 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 get deeply into the new MojoPac product from RingCube Technologies. After spending several days plumbing the depths of this intriguing new idea for installing secure and private Windows program and file installations onto transportable USB devices, I tell all about what I found and what I believe it means now and in the future.

Leo and I discuss the entire range of applications for Internet Proxies and Proxy Servers. We describe the many different uses for proxies while discussing both the benefits and the potential security and privacy liabilities created by filtering and caching web and other Internet content.

Leo and I discuss two new 0-day Internet Explorer vulnerabilities (both now being exploited on the Internet); then we explore the commonly expressed privacy and security concerns presented by the need to trust Internet Service Providers (ISP).

Completing the topic of current virtual machine technology and products, Steve and Leo closely examine the commercial multiplatform virtual machine offerings from "Parallels," comparing them to VMware and Virtual PC. Steve also corrects an important incorrect statement he made the previous week about features missing from VMware's free Server VM solution.

Leo and I discuss the breaking news of two new critical Windows problems: A new vulnerability that is being actively exploited on the web to install malware into innocent users' machines - and a work-around that all Windows users can employ to protect themselves. And a serious file-corruption bug Microsoft introduced into last month's security update that affects all Windows 2000 users.

Leo and I wrap up our multi-week series about virtual machines and virtual machine technology by closely analyzing the differences and similarities between the free and commercial VM products offered by Microsoft and VMware.
