Which of the following DoD policies establishes policies and assigns responsibilities to achieve DoD IA through a defense-in-depth approach that…

DoD Directive (DoDD) 8500.1, "Information Assurance (IA)," is the foundational policy document that establishes the DoD's overarching strategy for IA. The purpose statement within this directive explicitly states that it "Establishes policy and assigns responsibilities...to achieve information assurance (IA) through a defense-in-depth approach that integrates the capabilities of personnel, operations, and technology, and supports the evolution to network centric warfare." This wording directly matches the description provided in the question, identifying it as the correct high-level policy document. While this directive has been superseded, it remains a key historical document within the ISSEP body of knowledge.

A. DoD 8500.2 Information Assurance Implementation: This is an instruction that provides specific procedures and controls for implementing the high-level policy established in DoDD 8500.1, not the policy itself.

B. DoD 8510.1-M DITSCAP: This was the application manual for the DoD Information Technology Security Certification and Accreditation Process (DITSCAP), detailing a specific process, not the overarching IA policy.

C. DoDI 5200.40: This instruction formally established the DITSCAP framework. It is focused specifically on the Certification and Accreditation (C&A) process, which is only one component of the broader IA program.
