Unified Endpoint Management Server SRG: SRG-APP-000378-UEM-000248 (in versions v2 r3 through v1 r1)

Title

The UEM server must prohibit user installation of software by an administrator without the appropriate assigned permission for software installation. (Cat II impact)

Discussion

Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user. Application functionality will vary, and while users are not permitted to install unapproved applications, there may be instances where the organization allows the user to install approved software packages such as from an approved software repository. The application must enforce software installation by users based upon what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. This requirement applies, for example, to applications that provide the ability to extend application functionality (e.g., plug-ins, add-ons) and software management applications.
