“An Interactive Graph of the Certificate Authority Ecosystem”
December 14, 2012 | Posted by Soulskill, Slashdot.org

Researchers of the International Computer Science Institute in Berkeley have created an interactive diagram that shows root-CAs, their intermediates, the relationships between them and how many certificates have been signed by them. The graph was generated by passively monitoring the Internet uplinks of a number of (mostly) edu sites for SSL connections and their certificate Information.

“Boffins Birth Uber ‘Net Neutrality’ Dowser”
January 22, 2010 | Cade Metz, The Register

Researchers with the International Computer Science Institute in Berkeley, California have unveiled a completed version of their Netalyzr service, a tool designed to detect when your ISP is interfering with your net connection. The web-based service has been available as a beta since the middle of last year, but it's now set to collect mountains of data for a National Science Foundation-funded project that seeks to determine the state of so-called net neutrality.

“Revealing the Secrets of the Internet’s Gatekeepers”
May 25, 2010 | Jim Giles, New Scientist

Who controls your internet access? It's tempting to think that no one does. Sign up with an internet service provider (ISP) and that's it: you're free to browse. Well, not quite free. Your ISP is your internet gatekeeper. Many provide trouble-free service. But providers are able to slow down or block online activities such as file-sharing – an ability that the US Federal Communications Commission wants to rescind.

“Enterprises Not Ready for IPv6”
June 7, 2011 | Andy Dornan, InformationWeek

On Tuesday night, the world's largest carrier's providers and websites are switching on IPv6, the next-generation Internet protocol that's needed to deal with the looming address shortage. Most enterprise networks aren't ready, according to a survey from trade association CompTIA, which found that only 23% of business IT departments in the U.S. have actually begun to implement the new protocol.

"FCC Announces Net-Neutrality Competition Winners"
August 6, 2011 | Brendan Sasso, Hillicon Valley, The Hill

The Federal Communications Commission on Friday announced the winners of a contest to perform research or develop applications that protect the principle of net neutrality. The three winning teams were the University of Michigan and Microsoft Research; School of Computer Science, Georgia Institute of Technology; and the International Computer Science Institute Netalyzr Project.

Blue WatersGuest post by Adam Slagell, NCSA and the Bro team

The National Center for Supercomputing Applications (NCSA) at the University of Illinois faces unique security challenges as it must both maintain an open academic environment accessible to researchers around the world and protect some of the most valuable IT assets in the nation, a point brought home by the recent inauguration of the Blue Waters petascale computing system.

“US Internet Providers Hijacking Users’ Search Queries”
August 4, 2011 | Jim Giles, New Scientist

Searches made by millions of internet users are being hijacked and redirected by some internet service providers in the US. Patents filed by Paxfire, the company involved in the hijacking, suggest that it may be part of a larger plan to allow ISPs to generate revenue by tracking the sites their customers visit. It may also be illegal.

“Widespread Hijacking of Search Traffic in the United States”
August 4, 2011 | Peter Eckersley, the Electronic Frontier Foundation

Earlier this year, two research papers reported the observation of strange phenomena in the Domain Name System (DNS) at several US ISPs. On these ISPs' networks, some or all traffic to major search engines, including Bing, Yahoo! and (sometimes) Google, is being directed to mysterious third party proxies.

“Small ISPs Use “Malicious” DNS Servers to Watch Web Searches, Earn Cash”
August 5, 2011 | Nate Anderson, Ars Technica

Nearly 2 percent of all US Internet users suffer from "malicious" domain name system (DNS) servers that don't properly turn website names like google.com into the IP addresses computers need to communicate on the 'Net. And, to make matters worse, the problem isn't caused by hackers or malware, but by the local ISPs people pay for access to the Internet. Though the 2 percent number might sound low, it's astonishingly high for a core Internet function, as is clear from the fact that no other country—apart from Haiti—sees more than 0.17 percent malicious DNS servers. What's gone wrong in America?
