Our pattern represents in object-oriented form a model described in set terms in [San96]. That model has been the basis of most research papers and implementations of this idea [FBK99]. RBAC is implemented in a variety of commercial systems, including Sun s J2EE [Jaw00], Microsoft s Windows 2000, IBM s WebSphere, and Oracle, amongst others. The basic security facilities of Java s JDK 1.2 have been shown to be able to support a rich variety of RBAC policies [Giu99].

It allows administrators to reduce the complexity of security, because there are much more users than roles. Organization policies about job functions can be reflected directly in the definition of roles and the assignment of users to roles. It is very simple to accommodate users arriving, leaving, or being reassigned. All these actions require only manipulation of the associations between users and roles. Roles can be structured for further flexibility and reduction of rules. Users can activate more than one session at a time for functional flexibility some tasks may require multiple views or different types of actions. We can add UML constraints to indicate that some roles cannot be used in the same session or given to the same user (separation of duties). Groups of users can be used as role members, further reducing the number of authorization rules and the number of role assignments.

There are other possible structurings of roles [Fer94], which may be useful for specific environments. It is also possible to use roles to extend the multi-level model discussed in the next section.

Earlier versions of this pattern appeared in [Fer93] and [YB97], and a pattern language for its software implementation appears in [KBZ01], although this does not consider composite roles, groups, and sessions. The pattern shown in the figure below includes AUTHORIZATION (245) and COMPOSITE. Other related patterns are ROLE [Bau97], and ABSTRACT SESSION [Pry97].

8.3 Multilevel Security
In some environments data and documents may have critical value and their disclosure could bring serious problems. This pattern describes how to categorize sensitive information and prevent its disclosure. It discusses how to assign classifications (clearances) to users, and classifications (sensitivity levels) to data, and to separate different organizational units into categories. Access of users to data is based on policies, while changes to the classifications are performed by trusted processes that are allowed to violate the policies.
The high command of an army has decided on a plan of attack in a war. It is extremely important that this information is not known outside a small group of people, or the attack may be a failure.
In some environments data and documents may have critical value and their disclosure could bring serious problems.
How can you control access in an environment with sensitive documents so as to prevent leakage of information The solution to this problem must resolve the following forces:
We need to protect the confidentiality and integrity of data based on its sensitivity. Users have to be allowed to read documents based on their rank or position in the organization. There should be a way to increase or decrease the ability of users to read documents and the sensitivity of the documents. Otherwise, people promoted to higher positions, for example, could not read sensitive documents, and we would end up with a proliferation of sensitive and obsolete documents.
Assign classifications (as clearances) to users and classifications (as sensitivity levels) to data. Separate different organizational units into categories. For example,
