We live in a networked world - keeping in touch with friends, paying bills, operating a city’s energy grid, strengthening national security - it happens online. The need to secure our networks has never been greater. The number of cyber-attacks is increasing dramatically and there aren’t enough people with the right skills to fill mission-critical jobs needed to ensure our security online.

The course material is updated regularly to keep pace with changes in technology and threat landscape. It is an engaging, self-paced, easy-to-use combination of tutorials and videos where learners will come away with a solid foundation for building a career in cybersecurity or just strengthening their own home network.

It’s available as open courseware so learners can take it anytime and anywhere.
