Leo and I focus upon a comprehensive and highly recommended free software security vulnerability scanner called "PSI," Personal Software Inspector. Where anti-viral scanners search a PC for known malware, PSI searches for known security vulnerabilities appearing in tens of thousands of known programs. Everyone should run this small program! You'll be surprised by what it finds.

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 delve into the detailed operation of the YubiKey, the coolest new secure authentication device I discovered at the recent RSA Security Conference. Our special guest during the episode is Stina Ehrensvrd, CEO and Founder of Yubico, who describes the history and genesis of the YubiKey, and Yubico's plans for this cool new technology.

Leo and I discuss recent security news; then I describe the week I spent at the 2008 annual RSA security conference, including my chance but welcome discovery of one very cool new multifactor authentication solution.

Leo and I discuss an aspect of the "cost" of using the Internet - a packetized global network which (only) offers "best effort" packet delivery service. Since "capacity" is the cost, not per-packet usage, the cost is the same whether the network is used or not. But once it becomes "overused" the economics change since "congestion" results in a sudden loss of network performance.

Leo and I plow into the detailed operation of static and dynamic RAM memory to give some perspective to the recent Princeton research that demonstrated that dynamic RAM (DRAM) does not instantly "forget" everything when power is removed. They examine the specific consequences of various forms of physical access to system memory.
