Security+ Domain 01 - Fundamentals Of Security

These sources outline the fundamental pillars and methodologies used to build a robust cybersecurity posture. The documentation introduces the CIA Triad and CIANA model, which establish core goals like confidentiality, integrity, and availability, while the STRIDE frameworkprovides a systematic way to categorize and mitigate specific threats. Organizational security is further strengthened through security controls, classified by their function—such as preventive, detective, and corrective—and their implementation type, ranging from technical to physical. Strategic guidance is provided via the NIST Cybersecurity Framework 2.0, which utilizes Organizational Profiles to help entities conduct gap analyses and move from their current state toward targeted security outcomes. Additionally, the texts highlight modern defensive shifts like Zero Trust Architecture, which replaces implicit trust with continuous, policy-driven verification of all users and devices. Together, these materials serve as a comprehensive guide for identifying vulnerabilities, managing risks, and maintaining resiliency in an evolving digital landscape.
