Access Control Benchmark for FedRAMP Moderate Revision 4

The Access Control (AC) benchmark for FedRAMP Moderate Revision 4 provides guidelines for managing access to information systems and data within cloud service providers (CSPs) aiming for Federal Risk and Authorization Management Program (FedRAMP) Moderate authorization. This benchmark is aligned with the National Institute of Standards and Technology (NIST) Special Publication 800-53 Revision 4, outlining requirements for controlling access in CSP environments.

• Identification and Authentication: Implement strong user identification and authentication methods like multi-factor authentication and secure password policies.

• User Access Provisioning: Establish procedures for user registration, account activation/deactivation, and permission assignment following the principle of least privilege.

• Role-based Access Control (RBAC): Efficiently manage user access privileges based on roles and responsibilities to grant access to essential information and resources only.

• Access Enforcement: Use technical and procedural measures such as firewalls, intrusion detection systems, and encryption protocols to enforce access control policies.

• Monitoring and Auditing: Deploy robust monitoring and auditing mechanisms to monitor access activities, log user events, review system logs regularly, and conduct access reviews.

Following the Access Control (AC) benchmark for FedRAMP Moderate Revision 4 enhances the security of CSPs' cloud services, ensuring compliance with federal regulations. This benchmark is essential in safeguarding sensitive data, maintaining the privacy and integrity of information systems, and protecting against unauthorized access.

CSPs should regularly assess their access control mechanisms, review policies and procedures, and stay informed about emerging threats and vulnerabilities to effectively uphold compliance with the benchmark and safeguard customer data.
