摘要:
A policy language for an information management system has a three-layer structure that allows specifying one or more policies using policy abstractions. The policies and policy abstractions are in two different layers and decoupled from one another, so policies and policy abstractions may be specified and altered separately from each other. A third layer includes entity objects. A policy may refer to any number of policy abstractions. Multiple policies may reference a single policy abstraction, and a change to that policy abstraction will result in multiple policies being changed. Further, policy abstractions may be nested, so one policy abstraction may reference another policy abstraction, and so forth.

An information management system approves or denies user requests to access information of the system. The information includes all types of information including documents and e-mail. The information management system is driven using a policy language having policies and policy abstractions. The information management system may approve or deny many different types of requests including opening a document or file, copying a file, printing a file, sending an e-mail, reading an e-mail, cut and paste of a portion of a document, saving a document, executing an application on a file, and many others.

摘要:
To prevent conflicts of interest, an information management system is used to make sure two or more groups are kept apart so that information does not circulate freely between these groups. The system has policies to implement an “ethical wall” to separate users or groups of users. The user or groups of user may be organized in any arbitrary way, and may be in the same organization or different organizations. The two groups (or two or more users) will not be able to access information belonging to the other, and users in one group may not be able to pass information to the other group. The system may manage access to documents, e-mail, files, and other forms of information.
摘要:
A method and apparatus for controlling document access and application usage using centrally managed rules. The rules are stored and manipulated in a central rule database via a rule server. Policy enforcers are installed on client systems and/or on servers and perform document access and application usage control for both direct user document accesses and application usage, and application program document accesses by evaluating the rules sent to the policy enforcer. The rule server decides which rules are required by each policy enforcer. A policy enforcer can also perform obligation and remediation operations as a part of rule evaluation. Policy enforcers on client systems and servers can operate autonomously, evaluating policies that have been received, when communications have been discontinued with the rule server.
摘要:
In an information management system, policies are optimized before they are associated to a device in order to increase evaluation speed or reduce space requirements, or both. Optimization techniques may include common subexpression elimination, constant folding, constant propagation, comparison optimization, dead code or subexpression removal, map or lookup table generation, policy rewriting, redundant policy elimination, heuristic-based policy ordering, or policy-format transformation, and combinations of these.
摘要:
Code is associated to a target based on an inspection of the code. A target may be a device or a user. A number of code components may be inspected at one time and then transferred or otherwise associated to a target based on the target's profile. A code component may be a policy of an information management system.
