Authorisation is the process of granting or restricting access to system resources. Key aspects include:
Access Control:
- Define user permissions
- Restrict access to sensitive data
- Manage user roles and privileges
Implementation Methods:
- Role-based access control (RBAC)
- Attribute-based access control (ABAC)
- Rule-based access control
Authorisation Flow:
- User authentication
- Retrieve user permissions
- Check against resource requirements
- Grant or deny access
Security Considerations:
- Principle of least privilege
- Regular permission audits
- Secure storage of authorisation data
Common Challenges:
- Scalability for large user bases
- Maintaining fine-grained control
- Balancing security with usability
Authorisation ensures users can only access appropriate resources, enhancing system security.
