DNS attack puts Web security in perspective
I discussed the recent attack with VeriSign's chief security officer, Ken Silva. He said that the attack focused on root servers G (maintained by the U.S. Department of Defense) and L (maintained by ICANN), and to a lesser extent, M (maintained by Japan). During the 12-hour attack, nearly 90 percent of legitimate queries to those servers were being dropped.
That's a lot worse than I had been led to believe by other news sources. I hadn't questioned the other sources because I, like most people I know, didn't even notice the attack until it was over and had made headlines.
