Under MA.L2-3.7.2, what is the focus of CMMC practice regarding system maintenance?

The focus of the CMMC practice under MA.L2-3.7.2 emphasizes the need to control tools and techniques used for maintenance. This ensures that the processes involved in maintaining systems are secure, effective, and compliant with standards outlined by CMMC. Controlling the tools and techniques helps to minimize risks associated with unauthorized access or use of inappropriate tools, which could compromise system integrity and security.

In addition to ensuring security, controlling maintenance tools and techniques plays a critical role in maintaining the overall performance and reliability of systems. By training personnel on approved methods and ensuring that only designated tools are utilized, organizations can foster an environment of accountability and oversight during maintenance activities.

Focusing on the control of these tools and techniques also aligns with broader cybersecurity principles, advocating for proper management of system changes and updates, including how and when these changes are applied. This structured approach is crucial in managing vulnerabilities and ensuring the systems remain resilient against threats throughout their lifecycle.
