What are Security Boundary Constraints?

The correct choice identifies Security Boundary Constraints as the limitations in defining CMMC assessment boundaries. These constraints are vital in establishing the scope of a CMMC assessment. They help determine what systems, personnel, and data fall within the assessment's coverage. By clearly delineating these boundaries, organizations can ensure that their Cybersecurity Maturity Model Certification (CMMC) efforts are focused and efficient, addressing the necessary compliance requirements without overextending the assessment beyond relevant assets or operations.

Understanding Security Boundary Constraints is essential for effective planning and execution of cybersecurity assessments. These boundaries guide assessors in identifying what networks and systems will be evaluated for compliance, which is critical for both the accuracy of the assessment and the protection of sensitive information.

The other choices do not accurately capture the essence of Security Boundary Constraints. While barriers protecting sensitive information from physical threats refer to physical security measures, legal requirements for data protection relate to regulations and standards that organizations must follow, and resources required for system maintenance pertain to operational considerations rather than assessment scope.
