This week-long course is designed for high school students with cybersecurity experience. Students who have taken a cybersecurity course or participated on a competitive cybersecurity team will be challenged to take their skills to the next level. The course will challenge students to better understand cryptographic techniques, apply adversarial thinking to scenarios, identify and manage risk, and improve the cybersecurity of both traditional IT systems and the growing set of Internet of Things devices. Participants will be practicing their skills using Capture the Flag activities.
