This week, the Senate is considering a plan to improve cybersecurity. Its advocates say they want to prevent computer hackers from going after the power grid or other vital infrastructure in this country. Maryland Senator Barbara Mikulski contends a cyberattack could be worse than the freak storm that hit the nation's capital this summer.
The Internet is slowly becoming a less anonymous place. YouTube has a new policy encouraging commenters to use their real names, and many news sites have switched to a login system run by Facebook.
