The conceptual module of ACL
The final piece of the non-web tier security puzzle is security at the business object level, applied at or below the business tier. Security at this level is implemented using a technique known as ACL, or ACLs. Summing up the objective of ACLs in a single sentence—ACLs allow specification of a set of group permissions based on the unique combination of a group, business object, and logical operation.
For example, an ACL declaration for JBCP calendar might declare that a given user has to write access to his or her own event. This can be shown as follows:
|
Username |
Group |
Object |
Permissions |

ROLE_USER |
