Cyber-security starts at home and in the office

They did it for swine flu and now the Obama administration wants to convey clear and concise guidance about one of the biggest national security threats -- the computer. Former national intelligence director Michael McConnell said recently the Internet "is the soft underbelly" of the U.S. today with "a level of vulnerability that is unprecedented."

Whether a computer is in the home or office, the administration reminds people to think before they click. Officials note that what is said and done in cyberspace stays there -- for many to see, steal and use -- sometimes maliciously.

The Pentagon's computer systems are probed 360 million times a day, and one prominent power company has acknowledged up to 70,000 scans a day. Most probes are benign but others are aimed at espionage or tampering with or destroying data.
