|------------------------|------------------------------------------------------|----------------------------------------------------|------------------------------------------------------|------------------------------------------------------------|
|
|
| Access Control Basis | Based on identity of the requester and the discretion of the owner | Based on classifications and security clearances | Based on roles within an organization | Based on attributes (user, resource, environment) |
|
|
| Access Decision | Owners of the resource decide who can access it | System-enforced, not changeable by users | Access based on roles and their permissions | Decisions based on a set of policies involving attributes |
|
|
| Flexibility | Highly flexible with individualized control | Less flexible, focuses on classification levels | Moderately flexible, easy to manage | Highly flexible and granular |
|
|
| Complexity | Can become complex with many users and permissions | High, due to strict policy enforcement | Medium, depends on roles and permissions setup | High, due to complex policy definitions |
