IPv6: Coming sooner than you think
610707
(InfoWorld) - For many IT managers, IPv6 (Internet Protocol version 6), the next version of the Internet Protocol, may seem like a far-off concern. But the technology will make its way into corporate IT systems sooner than many people realize, forcing IT departments to confront potential security vulnerabilities inherent in the new protocol, a security consultant warned. Companies need toÂ prepare themselves for IPv6, even if they don't have plans to upgrade their networks, said Van Hauser, a security consultant and the founder of hacking group The Hacker's Choice. Hauser discussed security vulnerabilities in IPv6 this week during a presentation at the Hack In The Box Security Conference (HITB) in Kuala Lumpur, Malaysia. "Most people think there's no IPv6 now, so where's the problem?" Hauser said. "The thing is if you install any Unix operating system now it comes with IPv6 enabled." In addition,Â Microsoft's Vista operating system, set for release in the coming months, is expected to have support for IPv6 enabled, he said. With support for IPv6 enabled in these operating systems, IT managers need to prepared to address security issues in the new protocol. "It has the same vulnerabilites as IPv4 (IP version 4). When you thought with IPv6 everything will change in regards to security this is not really the case," Hauser said. Among the vulnerabilities that IPv6 and IPv4 share is the ability of a hacker to launch a man-in-the-middle attack, Hauser said. In this type of attack, a hacker is able to monitor or insert packets being sent back and forth between two parties, without either one realizing that the network link between them has been compromised by a third party. To secure against vulnerabilities in IPv6, companies must use IPSec (IP Security) on their networks, Hauser said. "If you use IPSec, most of the problems go away," he said. However, even then networks will not be completely secure. "It's not that easy. If you do encryption and authentication, it doesn't mean that security is okay," Hauser said. "It just narrows down the number of people who can do something."

Mike Wallner has thrown together some stats for the latest edition of the pecl/http package to test its response performance.   The results surprised me, because it clearly shows that the performance drop for starting the PHP engine and doing the neccessary negotiation to provide caching is not that bad.   There's a chart of the results as well as a full PDF with all of the stats the graph maps out. He includes the legend to make the graph easier to understand.
