S1 · E4 · 8 de sep. de 2005

Personal Password Policy (1) Episodio 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.

S1 · E5 · 15 de sep. de 2005

Personal Password Policy (2) Episodio 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.

S1 · E6 · 22 de sep. de 2005

Mechanical & Electromagnetic Information Leakage Episodio 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 CRT glowing, to radio emissions, to LEDs lamps on the front of network equipment . . . to a microphone listening to anyone typing.

S1 · E7 · 29 de sep. de 2005

SPYaWAREness Episodio 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!

S1 · E8 · 6 de oct. de 2005

Denial of Service (DoS) Attacks Episodio 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?

S1 · E9 · 13 de oct. de 2005

S1 · E11 · 27 de oct. de 2005

Bad WiFi Security (WEP and MAC address filtering) Episodio 11

Leo and I answer some questions arising from last week's episode, then plow into a detailed discussion of the lack of security value of MAC address filtering, the futility of disabling SSID's for security, and the extremely poor security offered by the first-generation WEP encryption system.

S1 · E12 · 3 de nov. de 2005

Sony's Episodio 12

Leo and I discuss details and consequences of Sony Corporation's alarming "Rootkit" DRM (digital rights management) copy protection scheme. This poorly written software unnecessarily employs classic rootkit technology (see episode #9) to hide from its users after installation. It can not be uninstalled easily, it can be easily misused for malicious purposes, and it has been implicated in many repeated BSOD "blue screen of death" PC crashes.

S1 · E13 · 10 de nov. de 2005

Unbreakable WiFi Security Episodio 13

Leo and I follow-up on last week's discussion of the Sony Rootkit debacle with the distressing news of "phoning home" (spyware) behavior from the Sony DRM software, and the rootkit's exploitation by a new malicious backdoor Trojan. We then return to complete our discussion of WiFi security, demystifying the many confusing flavors of WPA encryption and presenting several critical MUST DO tips for WPA users.

S1 · E14 · 17 de nov. de 2005

Virtual Private Networks (VPN): Theory Episodio 14

Leo and I first follow-up on the past two episodes, discussing new developments in the continuing Sony Rootkit DRM drama, and clearing up some confusion over the crackability of WPA passphrases. Then, in this first of our two-part series on VPNs, we discuss the theory of VPN connections and tunnels, explaining how they work and why they represent such a terrific solution for anyone who needs security while they're away from home.

S1 · E15 · 24 de nov. de 2005

VPN Secure Tunneling Solutions Episodio 15

Leo and I discuss the use of SSL and SSH encrypted tunneling for providing privacy and security whenever an insecure local network is being used — such as at an open WiFi hotspot or when using a hotel's network. These solutions are not transparent and tend to be configuration intensive. They also require the use of a "server" of some sort at the user's home or office. This makes these approaches less suitable for casual users, but offers a solution for the more technically inclined road warriors.

S1 · E16 · 1 de dic. de 2005

Listener feedback Q&A #1 Episodio 16

Leo and I discuss questions asked by listeners of our previous episodes.

S1 · E17 · 8 de dic. de 2005

PPTP and IPSec VPN Technology Episodio 17

In our continuing exploration of VPN technology for protecting network users on networks they don't control, Leo and I discuss the oldest "original" VPN protocols: Industry standard IPSec, and Microsoft's own PPTP and L2TP/IPSec. We examine and explain the trouble with interconnecting Windows machines to third-party VPN routers and examine the many reasons these older technologies are probably not optimal for on-the-go road warriors.

S1 · E18 · 15 de dic. de 2005

Hamachi Rocks! Episodio 18

This week Leo and I discuss and describe the brand new, ready to emerge from a its long development beta phase, ultra-secure, lightweight, high-performance, highly-polished, multi-platform, peer-to-peer and FREE! personal virtual private networking system known as "Hamachi". After two solid weeks of testing and intense dialog with Hamachi's lead developer and designer, I have fully vetted the system's security architecture and have it running on many of my systems. While I am travelling to Toronto this week, Hamachi is keeping my roaming laptop securely and directly connected to all of my machines back home. Don't miss this one!

S1 · E19 · 22 de dic. de 2005

VPNs Three: Hamachi, iPig, and OpenVPN Episodio 19

Leo and I wrap up our multi-week, in-depth coverage of PC VPN solutions by discussing some aftermath of the zero-configuration Hamachi system; introducing "iPig," a very appealing new zero-configuration VPN contender; and describing the many faces of OpenVPN, the "Swiss army knife" of VPN solutions.

S1 · E22 · 12 de ene. de 2006

The Windows MetaFile Backdoor? Episodio 22

Leo and I carefully examine the operation of the recently patched Windows MetaFile vulnerability. I describe exactly how it works in an effort to explain why it doesn't have the feeling of another Microsoft "coding error". It has the feeling of something that Microsoft deliberately designed into Windows. Given the nature of what it is, this would make it a remote code execution "backdoor". We will likely never know if this was the case, but the forensic evidence appears to be quite compelling.

S1 · E23 · 19 de ene. de 2006

GRC's Episodio 23

Leo and I "close the backdoor" on the controversial Windows WMF Metafile image code execution (MICE) vulnerability. We discuss everything that's known about it, separate the facts from the spin, explain exactly which Windows versions are vulnerable and why, and introduce a new piece of GRC freeware: MouseTrap which determines whether any Windows or Linux/WINE system has 'MICE'.

S1 · E24 · 26 de ene. de 2006
