🔍 What This Series Covers

Cybersecurity didn’t begin with the internet. It was forged in the fires of war, shaped by Cold War paranoia, defined by criminal ingenuity, and refined by decades of evolving standards and academic rigor. This series explores the foundational moments, models, threats, and figures that gave rise to the discipline we call cybersecurity today.

Each post in this series unpacks the historical arc—from Alan Turing’s cryptographic legacy and the first computer viruses, to models like Bell-LaPadula and frameworks like the Rainbow Series, all the way through to the layered defense principles and threat modeling we rely on now.

📚 Featured Topics

• Cryptographic foundations: Turing, Enigma, NSA history, and the intellectual roots of information security
• Early cyber threats: Creeper, Morris Worm, Mitnick, phreaking, and the rise of adversarial thinking
• Formal models: Bell-LaPadula, Biba Integrity Model, Clark-Wilson, and Multilevel Security (MLS)
• Government standards: The Rainbow Series, Common Criteria, Orange Book, and early DoD evaluation standards
• Architecture evolution: From perimeter firewalls to Zero Trust and layered defense-in-depth
• Lessons learned: What CISOs and security leaders today can learn from the past 50 years of mistakes and successes
