Security controls are the foundation of every cybersecurity strategy, providing the rules, tools, and enforcement mechanisms that protect data, systems, and operations from internal and external threats. In this episode, we introduce the concept of security controls and explain their importance in reducing risk, enforcing compliance, and maintaining the overall security posture of an organization. We explore how controls are implemented across technical, managerial, operational, and physical categories, and how they support core security goals like confidentiality, integrity, and availability. Listeners will learn how security controls intersect with risk management frameworks and serve as the backbone of a layered defense model. Understanding the purpose and structure of security controls is essential for anyone pursuing Security+, as it lays the groundwork for deeper discussions in later episodes.
