The National Nuclear Security Administration's (NNSA) mission includes maintaining and enhancing the U.S. nuclear weapons stockpile, reducing global danger from weapons of mass destruction, and providing safe and effective nuclear propulsion. To achieve its
mission goals, the NNSA utilizes many classified and unclassified computer networks and individual systems. Given the sensitivity of the infonnation residing on these networks and systems, strong cyber security measures are essential for protecting operational, personally identifiable, and other critical data from compromise. In Fiscal Year 2006, NNSA officials reported that they expended just over $90 million on cyber security in an effort to protect its information technology resources.
