The Common Body of Knowledge (CBK) refers to a comprehensive framework that outlines the essential knowledge areas and skills required in a specific field or profession. It serves as a standard reference for practitioners, educators, and students, ensuring a consistent understanding of key concepts and practices. The CBK is often used in certification programs, such as those offered by ISC2 for cybersecurity professionals. In the context of information security, the CBK includes various domains such as risk management, security architecture, and incident response. By defining these areas, the CBK helps professionals stay updated on best practices and emerging trends, ultimately enhancing their expertise and effectiveness in their roles.
