摘要： A cloud deployment appliance includes a mechanism to enable permitted users to move event records reliably from an internal event log of the appliance to a data store located external to the appliance while ensuring the integrity of event records. The mechanism ensures that the event records are not tampered with in storage or during download. Further, the approach ensures that no event records can be removed from the appliance internal storage before being successfully downloaded to the external data store.

摘要： A cluster system is treated as a set of resource groups, each resource group including a highly available application and the resources upon which it depends. A resource group may have between 2 and M data processing systems, where M is small relative to the cluster size N of the total cluster. Configuration and status information for the resource group is fully replicated only on those data processing systems which are members of the resource group. A configuration object/database record for the resource group has an associated owner list identifying the data processing systems which are members of the resource group and which may therefore manage the application. A data processing system may belong to more than one resource group, however, and configuration and status information for the data processing system is replicated to each data processing system which could be affected by failure of the subject data processing system—that is, any data processing system which belongs to at least one resource group also containing the subject data processing system. The partial replication scheme of the present invention allows resource groups to run in parallel, reduces the cost of data replication and access, is highly scalable and applicable to very large clusters, and provides better performance after a catastrophe such as a network partition.

摘要： An approach to handling integrated security roles is presented. An upstream application includes one or more role-mapping requirements that correspond to an upstream security role and a downstream security role. The upstream security role is expanded by adding an upstream security role identifier in a downstream application's role-mapping table or by adding upstream user-to-role mappings to a downstream application's role-mapping table. When an upstream security role is expanded, a user assigned to the upstream security role automatically has access to role-mapped downstream applications.

摘要： Objects on application servers may be defined into classes which receive different levels of security protection, such as definition of user objects and administrative objects. Domain-wide security may be enforced on administrative objects, which user object security may be configured separately for each application server in a domain. In a CORBA architecture, IOR's for shared objects which are to be secured on a domain-wide basis, such as administrative objects, are provided with tagged components during IOR creation and exporting to a name server. Later, when the IOR is used by a client, the client invokes necessary security measures such as authentication, authorization and transport protection according to the tagged components.

摘要： Embodiments of the present invention address deficiencies of the art in respect to access control and provide a method, system and computer program product for access control management for a collection of heterogeneous application components. In a first embodiment, a data processing system for role-based access control management for multiple heterogeneous application components can include at least one business role descriptor associating a business role with multiple, different application roles for corresponding, disparate application components. The system also can include at least one access policy associating a user with the business role. Finally, the system can include policy deployment logic include program code enabled to process the access policy to assign the user to the different application roles in the disparate application components.

摘要： A system and method is provided for reducing the complexity and improving the performance of enforcing security restrictions on the execution of program code in a runtime environment. In a preferred embodiment, units of executable code, such as methods or functions, are classified by “security level.” Code units belonging to a “trusted” security level may call any other code unit in the runtime environment, but other security levels are restricted in the code units they can call. Code units may also have “instance permissions” to allow them to have permission to call other individually-specified code units that they would normally be precluded from calling, due to their security level. The security level scheme described herein reduces the complexity of establishing permissions with respect to different code units in the runtime environment. This security level scheme also improves runtime performance by making it unnecessary to check individually-defined permissions in many cases.

In a preferred embodiment, units of executable code, such as methods or functions, are classified by “security level.” Code units belonging to a “trusted” security level may call any other code unit in the runtime environment, but other security levels are restricted in the code units they can call. In a preferred embodiment, the security levels are represented by corresponding permission objects. Each permission object that is associated with a particular security level includes a numerical value that denotes that security level. Security policies can be enforced with respect to caller and callee code units by comparing numerical values of corresponding permission objects. This security level scheme also improves runtime performance by making it unnecessary to check individually-defined permissions in many cases.

摘要： A method and system for providing a declarative trust association model that formalizes the way trust is established and requires corresponding authentication information to be presented in a standard format. Consequently, the application server may provide a guaranteed level of protection. The mechanism of the present invention provides a framework that allows an application server to enforce a trust evaluation and allows reverse proxy security server to assert a client's security identity, as well as other client security credential information. A known trust association interceptor model is extended to allow the reverse proxy security server to assert the authenticated user's security attributes. Such security attributes include, for example, group information, authentication strength, and location (i.e., where does the user enter the request, intranet vs. internet, IP address, etc.,). The security attributes can be used in making authorization decisions.
