On July 17, 2008, Senator Barack Obama held a town hall meeting on national security at Purdue University. He and his panel covered issues of nuclear, biological, and cybersecurity.
On February 9, 2009, President Obama appointed Melissa Hathaway as Acting Senior Director for Cyberspace and charged her with performing a comprehensive review of national cyberspace security in 60 days.
The report was delivered on or about April 10. Then, mostly silence to those of us on the outside. Several rumors were circulated in blogs and news articles, and there was a presentation at the RSA conference that didn't really say much. Hathaway resigned from her position this past August and the role of U.S. cybersecurity czar has been a continual topic of discussion.
