MFA combined with least privilege and RBAC restricts access to only authorized users, processes, and roles, minimizing the number of users who would be able to access or modify sensitive and non-sensitive files. Red Hat also enforces the principle of least functionality, ensuring that only essential features, services, and ports are enabled. This minimizes the number of components that could be affected through system compartmentalization. FIPS endpoints are enabled for all AWS GovCloud services that are used within the platform environment, ensuring that sensitive data stored on the system is encrypted or otherwise protected. Together, these controls help to prevent unauthorized access to files or the ability to manipulate the links to files.", "threat_severity": "Moderate"}
