Half of .gov sites fail DNSSEC test

netbuzz writes: U.S. federal government Web sites were mandated to have begun deploying DNS Security Extensions (DNSSEC) by Dec. 31, 2009, but a recent check shows that 51 percent have still failed to do so. That does represent a marked increase over the 20 percent that had complied as of a year ago. ``But if you think the government should be fully deployed by now, it’s a disappointing number,’’ says Mark Beckett, vice president of marketing and product management for Secure64, which conducted the study for Network World.
