For example, a senior administrator might have broader access rights than a junior administrator, allowing them to view and modify a wider range of cheat sheets and sections. This ensures that users with higher authority can perform their tasks effectively.
- Role-Specific Permissions: Tailor access rights based on specific roles and responsibilities. For instance, a security administrator should have access to security-related cheat sheets, while a network administrator should have access to network-related cheat sheets. This targeted approach limits exposure to sensitive information.
- Granular Control: Allow for granular control over permissions, granting access to specific cheat sheet sections instead of entire cheat sheets. For instance, a network administrator might need access to network troubleshooting cheat sheets but not to database administration cheat sheets. This approach minimizes potential risk and ensures data security.
