A Role-Based Access Control (RBAC) Matrix, also known as an Access Control Matrix or RBAC Model, is a framework used to define the roles within an organization and their access permissions to various resources. Use this matrix within your organization to streamline access rights by assigning permissions to roles rather than to individual users, making it easier to manage and audit access rights across a large organization. This matrix format helps in visualizing and managing the access rights associated with each role within the organization.
