60-Second Review

Express review

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

  1. Foundations: The CIA Triad and Early Threats. The CIA triad defines cybersecurity goals, and early incidents like the Morris Worm shaped the field.
  2. Social Engineering and Malicious Software. Ransomware, spyware, and social engineering exploit both technical weaknesses and human trust.
  3. Access Control and Security Governance. Strong authentication, clear policies, and structured risk management underpin organizational security.
  4. Standards, Training, and Insider Risk. Frameworks, awareness training, physical safeguards, and insider risk together shape organizational defense.
  5. Vulnerabilities and Patch Management. Zero-days, disclosure practices, the CVE system, and patching form the vulnerability lifecycle.
  6. Attacks, Breaches, and Regulation. DDoS attacks, botnets, major breaches, and regulations like GDPR shaped the modern threat landscape.
  7. Cyberwarfare and the Security Workforce. Stuxnet marked the arrival of cyberwarfare, while attribution and workforce gaps remain contested issues.
  8. The Business and Practice of Cybersecurity. Cybercrime economics, insurance, bug bounties, SOCs, and incident response shape modern security practice.

This is the starting point of Cybersecurity Fundamentals: you don't need any prior knowledge of this subject to begin.
