LinkScanner Pro - Stop zero-day Internet attacks
   LinkScanner Pro complements existing security products like a 
firewall or anti-virus by providing effective zero-day protection 
against web threats. Firewalls don't see these new threats because they 
use trusted browser connections. Anti-virus and anti-spyware programs 
only detect them after the damage has been done to the computer. 
LinkScanner provides real-time analysis of network traffic, web site 
content and behavior to protect users from a wide-range of online 
threats including malicious content, phishing, social engineering and 
targeted software exploits. Unlike products that use out-dated 
databases and questionable user feedback, LinkScanner's protection and 
site ratings are based on a current inspection of the web site and the 
data stream entering your computer. With LinkScanner, web surfing just 
became a whole lot safer.

=== IN FOCUS: Look Before You Leap into IPv6 with Teredo ======   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

We're told that the future of the Internet revolves around the IPv6 
protocol. Meanwhile, the majority of computers on the Internet still 
use IPv4. The two protocols are different enough that key software 
packages that are designed for IPv4 are unable to properly handle IPv6 
traffic. This is of course one of the major hurdles for IPv6 adoption. 

To help with this problem, Microsoft developed the open Teredo 
protocol, which tunnels IPv6 traffic over IPv4 networks when IPv6 
clients are behind some sort of Network Address Translation (NAT) 
device that doesn't understand IPv6. If you're interested in the 
technical specifications for Teredo, you can read RFC 4380, "Teredo: 
Tunneling IPv6 over UDP through Network Address Translations (NATs)," 
at the URL below. 
http://list.windowsitpro.com/t?ctl=4279B:7EB890 

Because Teredo is an open specification, Teredo software packages are 
available for a variety of platforms, including Mac OS X, Linux, BSD, 
and Sun Microsystems Solaris. One such package is Miredo, at the URL 
below. 
http://list.windowsitpro.com/t?ctl=4279F:7EB890 

For Windows, Teredo first appeared in service packs for Windows XP and 
Windows Server 2003. It's also a standard part of Windows Vista and 
will be a standard part of Longhorn when it's released. Teredo is a 
decent idea, however you should understand some security implications 
before you jump into using the technology. 

Last week, Symantec published a white paper titled "The Teredo 
Protocol: Tunneling Past Network Security and Other Security 
Implications," written by Dr. James Hoagland, principal security 
researcher with Symantec Advanced Threat Research. The white paper 
presents an examination of real and potential security problems. For 
example, Hoagland explains how worms that use network layer 3 or 4 
could use Teredo to escape a contained IPv6 network and reach remote 
IPv6 networks. You recall that the Slammer worm was able to propagate 
itself by using only one UDP packet. 

Hoagland also writes that security devices such as intrusion detection 
and prevention systems (IDSs/IPSs) that are designed for IPv4 don't 
understand IPv6 traffic. Thus, the IPv4 devices can't enforce adequate 
security controls on IPv6 traffic encapsulated in IPv4 packets.

Another problem is that Teredo might allow unwanted traffic into the 
IPv6 or IPv4 network. Other potential security problems relate to the 
possibility of creating a Denial of Service (DoS) condition in both 
Teredo clients and servers and the ability for remote systems to 
traverse the NAT in ways that are probably undesirable. 

If you're interested in using Teredo, by all means download a copy of 
Symantec's white paper (at the URL below) and read it over carefully. 
It might save you many headaches and answer a lot of questions before 
they even arise as a result of oddities in your network.
http://list.windowsitpro.com/t?ctl=42789:7EB890 

Keep in mind that the white paper discusses Teredo in general and is 
based on the associated RFC. Hoagland said that Symantec intends to 
look specifically at Teredo in Windows Vista sometime in the future. So 
keep an eye out for that white paper to become available.
