Sam Bocetta is a writer specializing in U.S. diplomacy and national security, with emphasis on technology trends in cyberwarfare, cyberdefense and cryptography. Much of his previous career was spent penetration testing ballistics computer systems for a variety of spacecraft, aircraft, and a few marine vessels. The cat-and-mouse game of finding security vulnerabilities and figuring out how to strengthen/eradicate them remains a fascination that he now explores through the written word.
