palegray.net writes "Researchers at the University of California have developed a new network routing algorithm that has the potential to significantly boost Internet traffic routing efficiency. This new approach focuses on the needs of dynamic networks, where connections are frequently transient. From the article: 'What the team did with their new routing algorithm, according to Savage's student Kirill Levchenko, was to reduce the "communication overhead" of route computation — by an order of magnitude.' For the technically inclined, the full research publication (PDF) is available."

Worm Threat Forces Apple To Disable Software? 201

SkiifGeek writes "After the debacle that surrounded the announcement and non-disclosure of a worm that targets OS X, the vulnerability in mDNSResponder may have forced Apple to remove support for certain mDNSResponder capabilities with the recently released Security Update 2007-007. 'Seeming to closely follow the information disclosed by InfoSec Sellout, Apple's mDNSResponder update addresses a vulnerability that can be exploited by an attacker on the local network to gain a denial of service or arbitrary code execution condition. Apple goes on to identify that the vulnerability that they are addressing exists within the support for UPnP IGD... and that an attacker can exploit the vulnerability through simply sending a crafted network packet across the network. With the crafted network packet triggering a buffer overflow, it passes control of the vulnerable system to the attacker. Rather than patching the vulnerability and retaining the capability, Apple has completely disabled support for UPnP IGD (though there is no information about whether it is only a temporary disablement until vulnerabilities can be addressed).'"

mjhuot writes "Last week SearchNetworking.com announced their Product Leadership Awards for 2007. It was a pleasant surprise to see an open source project, OpenNMS, win the Gold in their Network and IT Management Platforms category. OpenNMS beat out the established players of Hewlett-Packard's OpenView and IBM's Tivoli. This was based on a user survey of all IT solutions, not just open source; it demonstrates that open source software is indeed making inroads into the enterprise."

ancientribe writes "Father of the Internet Vint Cerf talks candidly in an article on Dark Reading about his being a Googler, and the biggest problems with Internet security and what he sees as the most promising solutions. He says that he's only done a little casual hacking, and that the term 'hacker' no longer comes with the honor it once did. Cerf also reveals in this personal look at the Internet icon that his real dream was to be an actor."
