Impact Levels (IL) are part of a classification system used by the DoD to categorize the sensitivity of information stored or processed in the cloud and the potential impact of an event that results in the loss of confidentiality, integrity, or availability of that information.
The DoD CC SRG defines specific security characteristics for each Impact Level:
- IL2: Includes Public or Non-Critical Mission Information.
- IL4: Includes Controlled Unclassified Information (CUI), such as For Official Use Only (FOUO), Personally Identifiable Information (PII), and Personal Health Information (PHI), Non-Critical Mission Information, and Non-National Security Systems (NSS).
- IL5: Includes higher sensitivity CUI, Mission Critical Information, and NSS. IL5 is between IL4 and IL6 but distinct for its inclusion of NSS.
- IL6: Includes information systems and information classified SECRET.
