IBM: Cybersecurity Basics: Tools and Cyberattacks

This course opens IBM's Cybersecurity Analyst learning path: it covers the evolution of cybersecurity, the motivations behind different attacker types, malware and ransomware threats, security architecture and controls, and identity/physical access management, with hands-on labs and a final project, plus video segments where working cybersecurity practitioners discuss their own careers and perspectives.

The honest take: with 121,851 learners and a 4-week, 4–8 hour/week self-paced structure, this is explicitly an entry point — IBM frames it as the first step toward becoming a Cybersecurity Analyst, not a comprehensive security course on its own. It's the right starting point for someone exploring the field, not someone who already has hands-on security experience.
