darthcamaro writes "Yesterday we discussed Google's launch of its new Public DNS service. Now Metasploit founder and CSO at Rapid7, H D Moore, investigates how well-protected Google's service is against the Kaminsky DNS flaw. Moore has put together a mapping of Google's source port distribution on the Public DNS service. In his view, it looks like the source ports are sufficiently random, even though they are limited to a small range of ports. The InternetNews report on Moore's research concludes: 'What Moore's preliminary research clearly demonstrates to me is that Google really does need to live up to its promise here. Unlike a regular ISP, Google will be subject to more scrutiny (and research) than other DNS providers.'"

eldavojohn writes "Benoit Felten, an analyst in Paris, has heard enough of the elusive creature known as the bandwidth hog. Like its cousin the Boogie Man, the 'bandwidth hog' is a tale that ISPs tell their frightened users to keep them in check or to cut off whoever they want to cut off from service. And Felten's calling them out because he's certain that bandwidth hogs don't exist. What's actually happening is the ISPs are selecting the top 5% of users, by volume of bits that move on their wire, and revoking their service, even if they aren't negatively impacting other users. Which means that they are targeting 'heavy users' simply for being 'heavy users.' Felten has thrown down the gauntlet asking for a standardized data set from any telco that he can do statistical analysis on that will allow him to find any evidence of a single outlier ruining the experience for everyone else. Unlikely any telco will take him up on that offer but his point still stands." Felten's challenge is paired with a more technical look at how networks operate, which claims that TCP/IP by its design eliminates the possibility of hogging bandwidth. But Wes Felter corrects that mis-impression in a post to a network neutrality mailing list.

Lucas123 writes "Researchers at Harvard Medical School pored over survey data from more than 4,000 'wired' hospitals and determined that computerization of those facilities not only didn't save them a dime, but the technology didn't improve administrative efficiency either. The study also showed most of the IT systems were aimed at improving efficiency for hospital management — not doctors, nurses, and medical technicians. 'For 45 years or so, people have been claiming computers are going to save vast amounts of money and that the payoff was just around the corner. So the first thing we need to do is stop claiming things there's no evidence for. It's based on vaporware and [hasn't been] shown to exist or shown to be true,' said Dr. David Himmelstein, the study's lead author."
