Challenges await Obama in bid to build up security

As President-elect Barack Obama prepares to take office, the task of upgrading the security of federal computer systems continues to be a work in progress. Several cybersecurity initiatives launched during the Bush administration are still years away from being completed. Others are closer to completion but don't do enough by themselves to defend networks and systems against increasingly sophisticated attacks, according to IT security analysts. And, they said, resolving the security issues will require Obama to focus on more than just finishing the ongoing initiatives.
