Today's a bad day security. First it was discovered that Microsoft accidentally leaked what amounts to a golden key for Secure Boot system, and now we find out there's a rather serious vulnerability in the TCP implementation in all Linux systems since version 3.6 of the Linux kernel was deployed four years ago. Is anyone safe? As it pertains to Linux, if exploited the vulnerability could allow attackers to sniff out hosts that are communicating over the protocol and hijack the traffic. And according to the researchers at the University of California, Riverside and the U.S. Army Research Laboratory who discovered the vulnerability, attackers don't even need to be in the traffic stream, otherwise...

Thanks to the efforts of some MIT researchers, our use of the Transmission Control Protocol could soon experience a nice upgrade. Since its introduction decades ago, TCP has become an integral part of our networking, whether we're connecting to another PC in the same building, or out to a remote server to fetch a webpage. In fact, because of its importance, TCP is one of the most-used pieces of software in the world. A lot has changed since TCP's introduction in the mid-70s, however. We're constantly changing what sort of data we're pushing across our network wire, and as such, there's never been just "one" TCP. While the overarching idea of TCP has always been to efficiently transfer data over...

Google's efforts to improve Internet efficiency through the development of the SPDY (pronounced "speedy") protocol got a major boost today when the chairman of the HTTP Working Group (HTTPbis), Mark Nottingham, called for it to be included in the HTTP 2.0 standard. SPDY is a protocol that's already used to a certain degree online; formal incorporation into the next-generation standard would improve its chances of being generally adopted. SPDY's goal is to reduce web page load times through the use of header compression, packet prioritization, and multiplexing (meaning combining multiple requests into a single connection). By default, a web browser opens an individual connection for each and every...

Google always does something "different" with the logo on its homepage on a holiday or other special occasion, and New Year's Day is no different. But it's not just about New Year's Day today.Today’s Google logo reads “2008” to celebrate new year’s, but also honors 25 years of TCP/IP. Clicking on it leads to a search result for the query January 1 tcp/ip. This protocol underlying the internet was fully switched to on January 1st, 1983, as Wikipedia’s entry on the subject knows.Look carefully at the confetti at the bottom of the logo to see if you can make out the special "message" there....
