Episode 21: Introduction to Security Controls
from Certified: The CCISO Audio Course Hosted by Dr Jason Edwards
This episode introduces the foundational concept of security controls and explains their critical role in any enterprise cybersecurity program. You’ll learn how controls are used to mitigate risk, enforce policy, and align security with business needs. We walk through the three primary categories of controls—preventive, detective, and corrective—and explore real-world examples of each, from firewalls and access restrictions to audit logs and incident containment procedures. This foundational understanding sets the stage for the more advanced discussions in later episodes across Domains 2 and 4. We also explore how control types map to the control families defined in popular frameworks such as NIST 800-53, ISO 27001 Annex A, and CIS Controls. You’ll hear how security leaders use these classifications to design layered defenses that account for technical, administrative, and physical risks. The episode also touches on control coverage, redundancy, and the importance of implementing safeguards that are proportionate to the threats and assets they’re meant to protect. Whether you're preparing for the exam or architecting your first security program, this is your starting point for thinking like a control strategist. Ready to start your journey with confidence?
