| Popis: | 104 Access control is an important part of information security. It decides how a user can legally obtain permission to access resources in appropriate situations. Because more information systems are deployed in a models enterprise, it become more complicated to set permissions. For example we may need new methods to set the permissions of a team. Since a team has specific targets and is composed of people, it may be difficult to use currently available access control methods. Since a team is composed of the team members and has target attributes, we proposed a new permissions model based on these team characteristics. The model, called Team RBAC, is based on Attribute RBAC. A user can define the team''s targets, the team member’s attributes and limitations, then the system can decide whether a team can be composed. The team will be given permissions if it is composed. Team RBAC has the advantages that it allows a more convenient management and can be more flexibly applied, because in Team RBAC, the attributes of a team can be dynamically modified. Two examples were presented to demonstrate possible applications of Team RBAC, one is an online game play treasure team composition, and the other is ISO audit team composition for a company. We also implemented a prototype system to show how an online gaming system can use Team RBAC model. |
