To effectively mitigate evolving cyber threats, the cybersecurity posture of the modern substation must be aligned with modern defense-in-depth strategies. SEL University designed APP 3620 to bridge the gap between foundational cybersecurity competencies and practical application.

APP 3620 is interactive and activity-based. During this course, you will configure and implement a realistic defense-in-depth cybersecurity scheme that uses the robust security features of the SEL-3620 Ethernet Security Gateway and modern security practices. Each unit of this course will guide you, step by step, through configuring this comprehensive cybersecurity scheme.


This course is intended for utility IT personnel, regulatory agency personnel, and communications and automation engineers.
