What is the MOST appropriate hierarchy of documents when implementing a security program?

The most appropriate hierarchy of documents when implementing a security program is organization principle, policy, standard, and guideline. An organization principle is a high-level statement that reflects the values, vision, and mission of the organization and provides the foundation for the security program. A policy is a formal document that defines the goals, objectives, and scope of the security program and assigns roles and responsibilities for its implementation and enforcement. A standard is a specific document that prescribes the mandatory rules, requirements, and procedures for achieving compliance with the policy. A guideline is a flexible document that provides recommendations, best practices, and tips for implementing the standards or addressing specific situations or issues. References: CISSP CBK Reference, 5th Edition, Chapter 1, page 12; CISSP All-in-One Exam Guide, 8th Edition, Chapter 1, page 6
