This class explores how significant government agencies around the world address the adversarial cyber risks facing them at the government and private sector levels, including their critical infrastructure sectors. Adversarial countries and criminal and hacking groups that engage in cyber weapon attacks will be covered, focusing on the types of cyber-attacks that are conducted, ranging from malicious breaches to political disinformation, as well as the motivations and tactics behind such attacks. Defense-in-depth principles, methodologies and tools, and the components of emergency response planning and strategic messaging required for effective cyber security programs will be covered. In addition to the weekly discussion, students will produce other assignments and projects that will focus on cyber threats and responses to cyber threats in different adversarial domains online. By the end of the course, students will also conduct an interview with a cyber personality that will be published online on a platform(s) to be determined.
