Definition
Principles are fundamental truths or propositions that serve as the foundation for a system of belief or behavior, or for a chain of reasoning. In technology, principles represent core concepts that guide the design, implementation, and management of systems. They provide a framework for making sound decisions and ensuring consistency across different projects and teams. Understanding principles helps professionals anticipate challenges and develop robust solutions. For instance, the principle of least privilege dictates that users and systems should only have the minimum necessary permissions to perform their tasks. This differs from specific policies, which are concrete rules, whereas principles are the underlying rationale. You will encounter principles extensively in domains like Security+, CySA+, and CISSP certification preparation.
