Key Insights

• 🧑‍🤝‍🧑 Cyber security is a well-established field with a history dating back to the mid-1960s, supported by reports, standards, and organizations.
• 👮 The field of cyber security extends beyond traditional computing and encompasses psychology, economics, law, and communication theory.
• 🤪 Building secure systems requires going back to First principles, prioritizing formal specification, and investing in research and development.

Questions & Answers

Q: What are the early precursors of the cyber security field?

The wear report, Anderson report, and the rainbow series were early reports and standards that defined cyber security issues and paved the way for the development of the field.

Q: Why is it difficult to define and achieve a clear definition of cyber security?

Cyber security involves complex systems and multifaceted challenges, making it challenging to establish a comprehensive definition. Additionally, economic constraints and the temptation to prioritize convenience over security pose obstacles to achieving a clear definition.

Q: How can software development practices contribute to the security of systems?

By incorporating formal specification and design, and investing in research and development for better system design, software development practices can enhance system security and reduce unexpected behaviors.

Q: What role does complexity play in the challenge of building secure systems?

Complexity in system design and the addition of layers and tools can lead to unanticipated failures and provide opportunities for attackers to exploit vulnerabilities. Simplifying system design and removing unnecessary complexity is crucial for security.

Summary & Key Takeaways

• Cyber security is a field that has a history dating back to the mid-1960s, with early reports and standards shaping its development.

• The field has developed a common body of knowledge, standard references, and terminology unique to cyber security.
