 # Permission & Security Metadata
 
-Permission metadata defines access control rules for objects, fields, actions, and views. It implements role-based access control (RBAC) and field-level security.
+Permission metadata defines access control rules for objects, fields, actions, and views using Role-Based Access Control (RBAC) and field-level security.

+ObjectQL's permission system provides a pure RBAC model with:
 
+- **Role-based access control**: Define roles and assign permissions to roles
 - **Object-level permissions**: Control CRUD operations on entire objects
 - **Field-level security**: Hide/protect sensitive fields from unauthorized users
 - **Record-level rules**: Dynamic filtering based on ownership, sharing, or custom rules

+## 11. Best Practices
 
 1. **Principle of Least Privilege**: Grant minimum necessary permissions
-2. **Role Hierarchy**: Use role inheritance to simplify management
+2. **Define Clear Roles**: Create well-defined roles that match organizational structure
 3. **Test Permissions**: Validate permission rules with different user roles
 4. **Document Rules**: Add clear descriptions to all permission rules
 5. **Regular Audits**: Review permissions regularly for compliance
 6. **Separation of Duties**: Prevent conflicts of interest with permission design
 7. **Default Deny**: Deny access unless explicitly granted
 
-## 14. Security Considerations
+## 12. Security Considerations
 
 1. **SQL Injection**: All permission filters use parameterized queries
 2. **Privilege Escalation**: Validate permission changes require admin access
 3. **Session Management**: Permissions cached per session, invalidated on role change
 4. **API Security**: Rate limiting on permission checks to prevent DoS
 5. **Audit Logging**: All permission denials logged for security analysis
