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. 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.

摘要： State management (cookie) data is encrypted so that access control data included in the cookie is unable to be modified by the user. A hashing algorithm is performed using various fields in the cookie data and the hash value is encrypted. The hash value is combined with other data such as the user identifier and a time stamp and encrypted to form a cookie value. When a request is received, the cookie data is checked. If the token value is not in the server's cache then the token is authenticated facilitating movement of the client between servers. If the cookie does not exist or is timed out, then the user is authenticated using traditional means.

摘要： A method, apparatus and computer instructions for handling propagation of custom tokens without using Java™ serialization. A service provider may plug in a first login module to add a marker token to a subject for later use by an application at run time. The marker token is then serialized by the mechanism of the present invention by invoking a get bytes method on the token. The present invention then propagates the token downstream if the token is marked forwardable. At a target server, a second login module may be plugged in to deserialize a byte array from a list of tokens and perform custom operation on the byte array retrieved from a token holder.

摘要： A method and apparatus for preventing rogue implementations of a security-sensitive class interface are provided. With the method and apparatus, a unique identifier (UID) is created by a server process when the server process is started. Anytime the server process, i.e. a server runtime environment, instantiates a new credential object following start-up of the server process, the encrypted UID is placed into a private field within the new credential object. In addition, the UID is encrypted and stored in a private class of the server runtime environment. A verification class is provided within the server runtime environment which includes one or more methods that receive the credential object as a parameter and return true or false as to the validity of the credential object. These one or more methods determine the validity of the credential object by retrieving the encrypted UID from the private class stored in the server runtime environment, decrypting the UID and comparing it to the decrypted UID stored in the private field of the credential object. If the two UIDs match, a determination is made that the credential object was created by the server runtime environment rather than a rogue application. If the two UIDs do not match, or if there is no UID in the credential object, then a false result will be returned by the verification class.

摘要： A system and method for tracking user security credentials in a distributed computing environment. The security credentials of an authenticated user includes not just his unique user identifier, but also a set of security attributes such as the time of authentication, the location where the user is authenticated (i.e., intranet user v. internet user), the authentication strength, and so on. The security attributes are used in access control decisions. The same user can be given different authorization if he has a different security attribute value. Security credentials may be generated either by WebSphere security code or by third party security provider code. This invention stores the user credentials in a distributed cache and provides a system and method to compute the unique key based on the dynamic security credentials for cache lookup

摘要： An extensible token framework is provided for identifying purpose and behavior of run time security objects. The framework includes a set of marker token interfaces, which extends from a default token interface. A service provider may implement one or more marker token interfaces for a Subject or a thread of execution. A service provider may also implement its own custom marker tokens to perform custom operations. The security infrastructure runtime recognizes behavior and purpose of run time security objects based on the marker or custom marker token interfaces the token implements and handles the security objects accordingly.

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.
