October is National Cyber Security Awareness Month (NCSAM), and 2013 marks the 10th anniversary of NCSAM. Increased connectivity and distributed networks make U.S. critical infrastructure and sensitive data vulnerable to attacks by criminals, hacktivists, and state and nonstate actors alike. As Director of National Intelligence James Clapper noted in his unclassified annual threat assessment to Congress in March 2013, “State and nonstate actors increasingly exploit the Internet to achieve strategic objectives, while many governments—shaken by the role the Internet has played in political instability and regime change—seek to increase their control over content in cyberspace.”
