Mapped to NIST 800-171 Requirement: 3.4.8
CMMC Assessment Objective: CM.L2-3.4.8[a]
What This Objective Means
This control focuses on identifying software and services that are:
• Not necessary for day-to-day operations
• Unused or rarely used
• Installed by default but not needed
• Common targets for exploitation
Examples of nonessential programs include:
• Media players, games, or browser toolbars
• Remote desktop tools not part of your approved access stack
• Vendor-installed bloatware or trialware
• Admin tools not used by your team
The goal is to reduce unnecessary complexity and minimize your threat surface, enhancing your compliance management system.
Why It Matters
Unused or unnecessary software increases the risk of:
• Vulnerabilities from unpatched software
• Misuse by insiders or attackers
• Configuration drift that complicates audits or incident response
Less software = fewer potential points of failure. Implementing effective compliance software can mitigate these risks.
How to Implement It
• Perform a software inventory on systems that handle or access CUI using an IT asset management system
• Identify:
◦ All installed applications
◦ System services and background tools
◦ Startup processes and scheduled tasks
• Review each item to determine:
◦ Is it required for a defined business or security purpose?
◦ Is it actively used?
◦ Is it vendor-approved or part of your baseline?
• Document which programs are deemed nonessential and flagged for removal or restriction
Evidence the Assessor Will Look For
• Software inventory or asset management reports
• Documentation showing which programs have been reviewed and marked as nonessential
• Risk analysis or security rationale for each program’s presence
• Alignment between your baseline configuration and system software lists
Common Gaps
• Default software is left installed without review
• No process to assess what’s essential vs. optional
• Legacy applications or utilities no longer in use but still present on systems
