In a Role-Based Access Control (RBAC) matrix, access levels are defined to specify what actions users can perform based on their assigned roles. The specific access levels may vary depending on the organization's needs and the complexity of its systems, but generally, the following access levels are commonly identified:
No Access: The user has no permissions to view, modify, or interact with the data or resources. This is suitable for users who should not have any interaction with the particular system or data.
Read-Only Access: The user can view data and resources but cannot make any changes. This is often granted to users who need to monitor information or generate reports without affecting the original data.
Read and Write Access: The user has permissions to both view and modify data. However, they may not have the ability to delete or manage access controls. This level is appropriate for employees who need to update records or input data as part of their job function.
Execute Access: The user can run or execute specific programs, scripts, or procedures but may not have the ability to alter the underlying code or configuration. This level of access is often used in systems where running tasks or jobs is required without modifying the application.
Create Access: The user may create new data or resources but might not have permissions to modify or delete existing ones. This could apply to roles tasked with adding new entries to databases or content management systems.
Delete Access: The user has permission to remove data or resources. This is a higher-level access often combined with other permissions and typically reserved for roles responsible for data lifecycle management.
Full Control/Admin Access: The user has complete control over the system, including managing other users' access rights, modifying configurations, and managing data. This level is usually restricted to administrators or superusers who require comprehensive abilities to oversee and maintain the system.
Custom Access: Some systems allow for custom access levels tailored to specific needs, combining various elements of the above-mentioned permissions. This could include access to certain features, modules, or datasets specific to the individual's role.
