Introduction to Data Security

It works through the three pillars of data security, GDPR compliance, the real consequences when a breach happens, and frameworks like the NIST Cybersecurity Framework — pitched at awareness level, so it's about understanding risks and responsibilities rather than implementing controls. That makes it a solid grounding for the many people who touch sensitive data without being security specialists, and too light if you want technical skills or already work in security. DataCamp charges a subscription (about $14/month billed annually, first chapter free), and its completion certificate marks what you covered, not a credential. One caveat: regulations vary by jurisdiction and change, so treat the GDPR and framework specifics as a starting point and check your own region (as of 2026).

Introduction to Data Security covers the fundamentals every data handler should know: the three pillars of data security, regulatory compliance (GDPR), real consequences of breaches, voluntary frameworks like the NIST CSF, and — in its strongest chapter — the human element: social engineering, phishing recognition, incident response, and building a genuine security-minded culture rather than relying on tools alone.
