Description

This three-day course provides an overview of cybersecurity principles and mechanisms and highlights the challenges of protecting computing systems from determined adversaries. The course provides an understanding of the foundational elements of information security. It also gives the student an awareness of the current threat environment and architectures, mechanisms and technologies used to contain constrain, and control adversarial actions.

Real world examples are provided to help understand the capabilities of cyber adversaries and the impact of their activities.

The course is valuable to scientists, engineers and operators who are entering the field or as a review for employees who want a comprehensive overview. A complete set of notes and references will be provided to all attendees.
