McAfee Inc. has jazzed up its Web site with a new online portal designed to help users research a wide range of security problems. Called the McAfee Threat Center, the portal was launched Monday as part of a redesign of the McAfee.com Web site.

Security will be a major focus this week at the giant Cebit show in Hanover, Germany. This year, the annual IT trade show will hone in on the multiple layers of security threats facing enterprise networks. Now it's not just data networks that are under attack; VoIP and even paper documents are at risk.
