DoD IL4/5
Also written: DoD Impact Level 4, DoD Impact Level 5
DoD security levels for handling controlled unclassified and classified defense information.
DoD Impact Levels 4 and 5 are security standards set by the U.S. Department of Defense. They define how sensitive government data can be stored and processed in cloud environments.
IL4 covers Controlled Unclassified Information (CUI), which is sensitive but not classified. IL5 covers additional categories of CUI and some types of classified information. Meeting these levels is crucial for defense contractors and government agencies wanting to use cloud services for their data.
Department of Defense (DoD) Impact Levels (IL) 4 and 5 are security categorizations that dictate the required security controls for handling specific types of DoD data in cloud computing environments. IL4 applies to Controlled Unclassified Information (CUI), while IL5 extends to CUI and certain categories of unclassified national security information. Achieving these impact levels is a prerequisite for DoD components and contractors to process and store sensitive data on authorized cloud platforms.
Anthropic's Claude AI has achieved approval for DoD IL4/5 workloads on Amazon Bedrock. This signifies a growing trend of major AI providers meeting stringent government security requirements to access lucrative public sector contracts.

While you cannot directly test DoD IL4/5 compliance, you can explore how AI models handle sensitive information by using a hypothetical scenario. Ask an AI model to draft a policy document for handling fictional sensitive employee data, paying attention to how it structures the information and what safeguards it implies.
