CM-7 (02)—Least Functionality | Prevent Program Execution
>Control Description
>FedRAMP Baseline Requirements
Additional Requirements and Guidance
CM-7 (2) Guidance: This control refers to software deployment by CSP personnel into the production environment. The control requires a policy that states conditions for deploying software. This control shall be implemented in a technical manner on the information system to only allow programs to run that adhere to the policy (i.e. allow-listing). This control is not to be based off of strictly written policy on what is allowed or not allowed to run.
>Discussion
Prevention of program execution addresses organizational policies, rules of behavior, and/or access agreements that restrict software usage and the terms and conditions imposed by the developer or manufacturer, including software licensing and copyrights. Restrictions include prohibiting auto-execute features, restricting roles allowed to approve program execution, permitting or prohibiting specific software programs, or restricting the number of program instances executed at the same time.
