Today, a large collection of Web hosting and service companies announced that they will support Railgun, a compression protocol for dynamic Web content. The list includes the content delivery network and Web security provider CloudFlare, cloud providers Amazon Web Services and Rackspace, and thirty of the world’s biggest Web hosting companies.

Railgun is said to make it possible to double the performance of websites served up through Cloudflare’s global network of data centers. The technology was largely developed in the open-source Go programming language launched by Google; it could significantly change the economics of hosting high-volume websites on Amazon Web Services and other cloud platforms because of the bandwidth savings it provides. It has already cut the bandwidth used by 4Chan and Imgur by half. “We've seen a ~50% reduction in backend transfer for our HTML pages (transfer between our servers and CloudFlare's),” said 4Chan’s Chris Poole in an e-mail exchange with Ars. “And pages definitely load a fair bit snappier when Railgun is enabled, since the roundtrip time for CloudFlare to fetch the page is dramatically reduced. We serve over half a billion pages per month (and billions of API hits), so that all adds up fairly quickly.”

Rapid cache updates

Like most CDNs, CloudFlare uses caching of static content at its data centers to help overcome the speed of light. But prepositioning content on a forward server typically hasn’t helped performance much for dynamic webpages and Web traffic such as AJAX requests and mobile app API calls, which have relatively little in the way of what’s considered static content. That has created a problem for Internet services because of the rise in traffic for mobile devices and dynamic websites.

DavidGilbert99 writes "Eugene Kaspersky and Mikko Hypponen have been watching the cyber security world every since happy hackers were writing viruses for nothing more than their own entertainment. Today however things are very much different. At the DLD 2013 conference, the pair debated the current state of cyber warfare and cyber weapons. Kaspersky said that while cyber weapons may be much 'cleaner' than traditional missiles, guns and bombs, they are 'much worse' as they can be used by just about anyone who has some level of computer proficiency. Both agreed that it was very difficult to protect against the highly-complex nation-state developed malware like Stuxnet, Flame and Gauss. Hypponen said that we are in the 'first stages of a cyber-arms race' warning: 'I think we've only seen the very beginning of these problems.'"

An anonymous reader writes "Details of the tools, techniques and procedures used by the hackers behind the RSA security breach have been revealed in a research paper (PDF) published by Australian IT security company Command Five. The paper also, for the first time, explains links between the RSA hack and other major targeted attacks. This paper is a vendor-neutral must-read for any network defenders concerned by the hype surrounding 'Advanced Persistent Threats.'"
