What security controls govern data access and classification in MCP?

What security controls govern data access and classification in MCP?

• A. Data is publicly accessible with no controls
• B. Data classification levels, role-based access, least privilege, audit logging, encryption at rest/in transit, and periodic permission reviews
• C. Access is granted to all users by default
• D. Only password protection

Answer: (B)

Data access and classification in MCP are governed by a layered set of security controls that enforce who can view data, what data they can access, and how that data is protected. Labeling data with classification levels sets the protection and access requirements for each asset. Role-based access ties those requirements to a user’s duties, ensuring people can only access what their role permits, and the principle of least privilege minimizes exposure by giving only the permissions truly needed. Audit logging continuously records who accessed what and when, creating an traceable history that supports accountability and investigators if something goes wrong. Encryption at rest and in transit protects data even if it is accessed without authorization, while periodic permission reviews keep access aligned with changing roles and responsibilities, reducing drift over time. Together, these controls create a defense-in-depth approach that protects sensitive information while supporting proper, auditable access. The other options imply no controls, universal access, or only password protection, which fail to address data labeling, access rights, monitoring, or encryption and thus leave data exposed or improperly managed.
