Five must-do cybersecurity steps for Obama

As President-Elect Barack Obama looks for ways to deal with a shattered economy and an ongoing war on terrorism, security experts are urging him to pay attention to something that has a big impact on both: The nation's growing -- and fragile -- cyberinfrastructure. Potential adversaries have increasingly turned to cyberespionage as a way to find weaknesses in networks run by the government and the nation's critical infrastructure providers. Realistically, most of the necessary improvements must be devised and deployed from within private companies and government agencies. But Obama is in a unique position to lead on this issue and inspire others to fix the security holes, experts say.
