Cyber Security – Legacy Career Learning Hub

About Course

This course provides learners with a deep understanding of cyber threats, security technologies, and defensive strategies to protect systems, networks, and data. It combines theory with hands-on practical labs to prepare students for both defensive (blue team) and offensive (red team) cybersecurity roles.

Students will learn how to identify vulnerabilities, secure systems, analyze attacks, and apply modern cybersecurity tools and frameworks used globally.
