What is a requirement for doD Information Systems under DoDI 8500.01?

The requirement for DoD Information Systems under DoDI 8500.01 emphasizes the need for a structured and comprehensive approach to cybersecurity risk management. Implementing multi-tiered cybersecurity risk management allows organizations to identify, assess, and mitigate risks associated with their information systems effectively. This approach ensures that multiple layers of security controls are applied, which helps in addressing both technical and operational vulnerabilities that may exist within the systems.

This methodology is essential because it aligns with the DoD's broader objective of maintaining the integrity, confidentiality, and availability of its information systems. Each layer in the risk management strategy offers a different perspective and set of controls, contributing to a more holistic defense against insider threats and external attacks.

The other options provide responses that do not fully align with the comprehensive risk management framework required by DoDI 8500.01. Limiting encryption to only sensitive data, for example, does not capture the need for broad-spectrum protective measures for all types of data. Restricting access to physical hardware exclusively overlooks the necessity for strong cybersecurity practices that extend beyond physical access controls. Conducting outdoor penetration tests does not relate specifically to risk management protocols and may not address internal vulnerabilities adequately.
