Episode 1 - How a never-disclosed Windows vulnerability was quickly reverse-engineered from the patches to fix it and turned into more than 12 potent and damaging Internet worms in three days. What does this mean for the future of Internet security?

Episode 2 - How Microsoft's “HoneyMonkey” system works, how it finds malicious web sites before they find you, and what Microsoft is doing (and NOT doing) with this valuable security information it is now collecting.

Episode 3 - How and why any simple NAT Router makes a terrific hardware firewall. (And what you must disable to prevent it from being bypassed!)

Episode 4 - Everyone who uses web-based services such as eBay, Amazon, and Yahoo, needs to authenticate their identity with passwords. Password quality is important since easily guessable passwords can be easily defeated. Leo and I recap a bit from last week's program, then discuss passwords. We suggest an approach that anyone can use to easily create unbreakable passwords.

Episode 5 - Our previous episode (#4), which discussed personal password policies, generated so much great listener feedback, thoughts, ideas, and reminders about things we didn't mention, that we decided to wrap up this important topic with a final episode to share listeners' ideas and to clarify some things we left unsaid.

Episode 6 - Triggered by a recent report of three UC Berkeley researchers recovering text typed at a keyboard (any keyboard) after simply listening to ten minutes of typing, Leo and I discuss the weird realm of “alternative information leakage” - from CRTs glowing, to radio emissions, to LED lamps on the front of network equipment…to a microphone listening to anyone typing.

Episode 7 - Any contemporary discussion of threats to Internet security must discuss the history, current situation, and future of spyware. Leo and I spend a little more time than usual covering many aspects of this important topic. DON'T MISS the Episode Notes Page for this episode!

Episode 8 - Distributed Denial of Service (DDoS) attacks are occurring with ever-greater frequency every day. Although these damaging attacks are often used to extort high-profile gaming and gambling sites before major gambling events, attacks are also launched against individual users who do something to annoy “zombie fleet masters” while they are online. Some router and firewall vendors claim that their devices prevent DDoS attacks. Is that possible? What can be done to dodge the bullet of a DDoS attack launched against you while you're online?

Episode 9 - This week we explain “rootkit technology.” We examine what rootkits are, why they have suddenly become a problem, and how that problem is rapidly growing in severity. We also discuss their detection and removal and point listeners to some very effective free rootkit detection solutions.

Episode 10 - Leo and I examine the security and privacy considerations of using non-encrypted (i.e., “Open”) wireless access points at home and in public locations. We discuss the various ways of protecting privacy when untrusted strangers can “sniff” the data traffic flowing to and from your online PC.
