By the end of next year, you can be confident that every U.S. government Web page is being served up by the appropriate agency. That's because the feds have launched the largest-ever rollout of a new authentication mechanism for the Internet's DNS. All federal agencies are deploying DNS Security Extensions (DNSSEC) on the .gov top-level domain, and some expect that once that rollout is complete, banks and other businesses might be encouraged to follow suit for their sites. DNSSEC prevents hackers from hijacking Web traffic and redirecting it to bogus sites. The Internet standard prevents spoofing attacks by allowing Web sites to verify their domain names and corresponding IP addresses using digital signatures and public-key encryption."
