Abstract: 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.

Abstract translation: 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。

Abstract: 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.

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). Evidence having different levels of trust may be evaluated in combination so that a permission grant set is associated only with trusted code assemblies. 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.

Abstract: 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.

Abstract: Described is a mechanism for collectively evaluating security risks associated with loading an application. A hosting environment associated with loading the application invokes a trust manager to evaluate the security risks. The trust manager invokes a plurality of trust evaluators, where each trust evaluator is responsible for analyzing and assessing a different security risk. Upon completion of each security risk evaluation, results of those individual security risk evaluations are returned to the trust manager. The trust manager aggregates the variety of security risk evaluation results and makes a security determination based on the aggregated evaluation results. That determination may be to move forward with loading the application, to block the load of the application, or perhaps to prompt the user for a decision about whether to move forward with the load.

Abstract translation: 描述了一种用于集体评估与加载应用程序相关的安全风险的机制。 与加载应用程序相关联的托管环境将调用信任管理器来评估安全风险。 信任管理员调用多个信任评估者，每个信任评估者负责分析和评估不同的安全风险。 完成每次安全风险评估后，将个人安全风险评估结果退还给信托经理。 信托经理综合各种安全风险评估结果，并根据总体评估结果进行安全性评估。 该确定可能是在加载应用程序时向前推进，以阻止应用程序的加载，或者可能提示用户关于是否向前移动负载的决定。

Abstract: A system and method that allows developers to debug a component while it is restricted by any arbitrary set of specific permissions, or restricted by an existing permission set associated with a security “zone.” A security sandbox is mimicked within the development environment so that developers can study how applications perform inside the sandbox. Developers are able create any sandbox and debug inside it, where violating any bound of the artificial sandbox will throw a security exception and drop the user out on the exact line of code which generated the error, as well as provide helpful information about how to correct the error.
