CM.L2-3.4.9  

Reference: CMMC v2.13

Family: CM

Level Introduced: 2

Title: User-Installed Software

Practice:
Control and monitor user-installed software.

Further Discussion:
Software that users have the ability to install is limited to items that the organization approves. When not controlled, users could install software that can create unnecessary risk. This risk applies both to the individual machine and to the larger operating environment. Policies and technical controls reduce risk to the organization by preventing users from installing unauthorized software.

Example
You are a system administrator. A user calls you for help installing a software package. They are receiving a message asking for a password because they do not have permission to install the software. You explain that the policy prohibits users from installing software without approval [a]. When you set up workstations for users, you do not provide administrative privileges. After the call, you redistribute the policy to all users ensuring everyone in the company is aware of the restrictions.

Potential Assessment Considerations
• Are user controls in place to prohibit the installation of unauthorized software [a]?
• Is all software in use on the information systems approved [b]?
• Is there a mechanism in place to monitor the types of software a user is permitted to download (e.g., is there a whitelist of approved software) [c]?
