In cooperation with the United States Digital Service, and the Federal Risk and Authorization Management Program, CISA released the Cloud Security (CS) Technical Reference Architecture (TRA). The CS TRA defines and clarifies considerations for shared services, cloud migration, and cloud security posture management. While the guide directs federal civilian departments and agencies, as with all CISA guidance and reference documents, the CS TRA is useful and intended for all organizations to review and implement when migrating to the cloud.
