Introduction¶
Security principles are the foundation of any robust security architecture. They provide timeless, reusable guidance that helps architects and engineers make consistent, defensible decisions — regardless of which technologies or products are used.
In this section, you will learn why principles matter more than specific solutions, and how applying them early prevents costly redesigns later.
Learning Objectives¶
By the end of this section, you will be able to:
Explain what a security principle is and how it differs from a requirement or control
Understand why principles must be applied at every process step within cybersecurity activities
Recognise and apply all key Security by Design principles
