An emerging technology promises to improve the security of the Internet's infrastructure by preventing hackers from hijacking Web traffic and redirecting it to bogus sites. The new security mechanism, dubbed DNSSEC, plugs a hole in the Internet's Domain Name System (DNS) that hackers have exploited to spoof Web sites. DNSSEC prevents these attacks by allowing Web sites to verify their domain names and corresponding IP addresses using digital signatures and public-key encryption.

"DNSSEC is going to be a huge advancement for security on the 'Net," says Mark Kosters, vice president of research at Network Solutions.
