The Security Control Traceability Matrix (SCTM) is a crucial tool for organizations seeking CMMC certification. It is used to map and track the implementation of specific security controls against the requirements of the CMMC framework. It provides a clear and detailed map of how each CMMC practice is addressed and can be used as a communication tool within the organization, helping various departments understand their roles and responsibilities in implementing and maintaining CMMC-related security controls. The SCTM aids in compliance efforts, gap analysis, risk management, and effective communication of security controls both internally and during external assessments.
