CM-11: User-installed Software

If provided the necessary privileges, users can install software in organizational systems. To maintain control over the software installed, organizations identify permitted and prohibited actions regarding software installation. Permitted software installations include updates and security patches to existing software and downloading new applications from organization-approved app stores. Prohibited software installations include software with unknown or suspect pedigrees or software that organizations consider potentially malicious. Policies selected for governing user-installed software are organization-developed or provided by some external entity. Policy enforcement methods can include procedural methods and automated methods.

NSO - Boundary is specific to SaaS environment; all access is via web services; users' machine or internal network are not contemplated. External services (SA-9), internal connection (CA-9), remote access (AC-17), and secure access (SC-12 and SC-13), and privileged authentication (IA-2[1]) are considerations.
