摘要： An isolated persistent storage object accesses an isolated persistent storage region using identities of the application, an underlying component of the application, and optionally the user. Direct access to the isolated persistent storage region is available only to the isolated persistent storage object and is unavailable to other components. Accordingly, other components access the isolated persistent storage region through the isolated persistent storage object, which determines the specific location (e.g., specified by an internally constructed path name) and performs the access operation on behalf of the calling component. The application identity and the component identity are converted to typed identity names for use in the construction of the path name.
摘要翻译：孤立的持久存储对象使用应用程序的标识，应用程序的底层组件以及可选的用户来访问隔离的持久存储区域。对隔离的持久存储区域的直接访问仅对隔离的持久存储对象可用，对其他组件不可用。因此，其他组件通过隔离的持久存储对象访问隔离的持久存储区域，该隔离的持久存储对象确定特定位置（例如，由内部构造的路径名称指定），并代表主叫组件执行访问操作。应用程序标识和组件标识将转换为类型化的标识名称，以用于构建路径名。

摘要： An evidence-based policy manager generates a permission grant set for a code assembly received from a resource location. The policy manager executes in a computer system (e.g., a Web client or server) in combination with the verification module and class loader of the run-time environment. The permission grant set generated for a code assembly is applied in the run-time call stack to help the system determine whether a given system operation by the code assembly is authorized. Both code assemblies and evidence may be received from a local origin or from a remote resource location via a network (e.g., the Internet). The policy manager may comprise execution modules for parsing a security policy specification, generating a one or more code hierarchies, evaluating membership of the received code assembly in one or more code groups, and generating a permission grant set based upon this membership evaluation.

摘要： A system and method determine whether a called code frame has a requested permission available to it, so as to be able to execute a protected operation. A code frame is contained within a code assembly received from a remote or local resource location. A policy manager generates a permission grant set containing permission grant objects associated with the code assembly. Both the permission grant set and the code assembly are loaded into a runtime call stack for runtime execution of one or more code frames. Calls to other code frames may involve loading additional code assemblies and permission grant sets into the runtime call stack. In order for a called code frame to perform a protected operation, the code frame demands a requested permission from its calling code frame and all code frames preceding the calling code frame on the runtime call stack as part of a stack walk operation. If the calling code frame and the preceding call frames can satisfy the requested permission, the called code frame can perform the protected operation (absent stack overrides). Otherwise, a security exception is thrown and the called code frame is inhibited from performing the protected operation (absent stack overrides). Stack overrides may be employed to dynamically modify the stack walk operation. To increase performance, a stack walk may be avoided by caching an intersection of the permission grants of all code assemblies in the application.
摘要翻译：一种系统和方法确定被叫代码帧是否具有可用的请求权限，以便能够执行受保护的操作。代码帧包含在从远程或本地资源位置接收的代码集合中。策略管理器生成包含与代码集合相关联的许可授权对象的许可权授予集。许可授予集和代码集合都被加载到运行时调用堆栈中，以便运行时执行一个或多个代码帧。对其他代码帧的调用可能涉及将额外的代码组合和许可授权集合加载到运行时调用堆栈中。为了使被叫代码帧执行受保护的操作，代码帧需要其调用代码帧和运行时调用堆栈之前的调用代码帧之前的所有代码帧的请求许可，作为堆栈步骤操作的一部分。如果呼叫代码帧和前面的呼叫帧可以满足请求的权限，则被叫代码帧可以执行受保护的操作（不存在堆栈覆盖）。否则，将抛出安全异常，并禁止调用的代码帧执行受保护的操作（不存在堆栈覆盖）。可以采用堆叠覆盖来动态地修改堆栈行进操作。为了提高性能，可以通过缓存应用程序中所有代码程序集的许可授权的交集来避免堆栈移动。

摘要： A security policy manager generates a permission grant set for a code assembly received from a resource location. The policy manager can execute in a computer system (e.g., a Web client) in combination with the verification module and class loader of the run-time environment. The permission grant set generated for a code assembly is applied in the run-time call stack to help the system determine whether a given system operation by the code assembly is authorized. A permission request set may also be received in association with the code assembly. The permission request set may include a minimum request set, specifying permissions required by the code assembly to run properly. The permission request set may also include an optional request set, specifying permissions requested by the code assembly to provide an alternative level of functionality. In addition, the permission request set may include a refuse request set, specifying permissions that are not to be granted to the code assembly. The permission requests are used to filter a permission set to generate a permission grant set.

Both code assemblies and evidence may be received from a local origin or from a remote resource location via a network (e.g., the Internet).

The policy manager may comprise execution modules for parsing a security policy specification, generating one or more code hierarchies, evaluating membership of the received code assembly in one or more code groups, and generating a permission grant set based upon this membership evaluation.
