摘要： The techniques and mechanisms described herein are directed to a scripting security mechanism that minimizes security risks associated with interpreting a script written with a scripting language. An interpreter recognizes the scripting-language syntax within the script and processes each line that is designated within a data block using a restrictive set of operations. The restrictive set of operations are a subset of the total operations available for processing. If one of the lines within the data block attempts to perform an operation that is not within the restrictive set of operations, the interpreter provides an indication, such as an exception or message explaining the illegal operation. The interpreter also recognizes a list of export variables associated with the data block and exports only the variables identified in the list to an external environment if the export variable meets a constraint identified for it, if any.

摘要： The techniques and mechanisms described herein are directed to a taint mechanism. An object-based command declares a taint directive for a parameter within a command declaration. The taint directive is then associated with that parameter in a manner such that when an engine processes the command, the engine determines whether to process the command based on the taint directive and input for the parameter. The taint directive may specify that the input may be tainted or untainted. The command declaration may also include a taint parameter that specifies a taint characteristic for output from the command. The taint characteristic may be tainted, untainted, or propagated. Any type of object may become tainted. An untaint process may be applied to tainted data to obtain untainted data if an authorization check performed by the engine is successful.
摘要翻译： 本文描述的技术和机制针对污染机制。 基于对象的命令在命令声明中声明一个参数的污点指令。 然后，污染指令以这样的方式与该参数相关联，使得当引擎处理命令时，引擎根据污点指令和参数的输入来确定是否处理命令。 污点指令可能指定输入可能被污染或未被保留。 命令声明还可以包括一个污染参数，该参数指定了从命令输出的污点特性。 污点特性可能会被污染，未被维护或传播。 任何类型的物体可能会被污染。 如果发动机执行的授权检查成功，则可以将污染过程应用于污染数据以获得未维护的数据。

摘要： The techniques and mechanisms described herein are directed to an interpreter security mechanism that minimizes security risks associated with interpreting a script written with a scripting language. The interpreter security mechanism recognizes a marker that indicates a beginning for a set of non-interpreted lines. Upon recognizing the marker, the interpreter refrains from interpreting subsequent lines in the script until an end of marker occurs or an end of file occurs. The end of marker indicates that the interpreter can resume interpreting the lines in the script that follow the end of marker.

摘要： The present comparison technique operates on objects having the same type, similar types, or different types. Multiple comparison objects may be compared against one or more reference objects. The comparison objects may be obtained from a prior cmdlet in a pipeline of cmdlets operating in an object-based environment. The reference object and comparison object may be compared in an order-based manner or in a key-based manner. In addition, specific properties may be specified which will identify which properties of the reference object and the comparison object to compare during the comparison. The comparison may generate an output that identifies the difference and/or similarities. The output may be pipelined to another cmdlet for further processing.

摘要： The techniques and mechanisms described herein are directed at converting text into objects based on a template that describes the format of the text. The objects then being available for further processing. The conversion mechanism converts the text into an object having at least one method that is directly invocable and that is specific to a data type specified for the live object. The template comprises an object header indicator and a corresponding object header pattern. A new object is created whenever the object header pattern is identified within the text. In addition, the template comprises one or more field indicators each having a corresponding field pattern. The field pattern is in a format of a regular expression. A new field is created for the new object whenever a field pattern is identified within the text.

摘要： The techniques and mechanisms described herein are directed at converting text into objects based on a template that describes the format of the text, where the format of the text is not in a standardized format. The objects then being available for further processing. The conversion mechanism converts the text into a dead object. The template comprises an object header indicator and a corresponding object header pattern. A new object is created based on the object header pattern identified within the text. In addition, the template comprises one or more field indicators each having a corresponding field pattern. The field pattern may be in a format of a regular expression. A field type and associated value are created from a string associated with the field pattern.
摘要翻译： 本文描述的技术和机制旨在基于描述文本的格式的模板将文本转换为对象，其中文本的格式不是标准化格式。 然后可以进行进一步处理。 转换机制将文本转换为死对象。 模板包括对象标题指示符和相应的对象标题模式。 基于文本中标识的对象标题模式创建一个新对象。 另外，模板包括一个或多个场指示器，每个场指示器具有对应的场模式。 场图案可以是正则表达式的格式。 字段类型和关联值是从与字段模式相关联的字符串创建的。

摘要： The techniques and mechanisms described herein are directed to an extensible security architecture that provides a security mechanism for minimizing security problems within interpretive environments. The extensible security architecture comprises a script engine configured to process a script and a security manager configured to monitor the processing of the script based on a security policy. The security manager determines whether to open an assembly associated with a command within the script, whether to process the command, whether to allow certain input to the command, and the like. The security policy may be implemented by overriding one or more methods of a base security class that are called when processing the script. The input may be an object passed via an object-based pipeline.

摘要： In an administrative tool environment, user input is supplied to an administrative tool framework for processing. The administrative tool framework maps user input to cmdlet objects. The cmdlet objects describe a grammar for parsing the user input and input objects to obtain expected input parameters. The input objects are emitted by one cmdlet and are available as input to another cmdlet. The input objects may be any precisely parseable input, such as .NET objects, plain strings, XML documents, and the like. The input objects are not live objects. The cmdlets may operate within the same process. Alternatively, one cmdlet may operate locally while another cmdlet operates remotely. The cmdlets may be provided by the administrative tool framework or may be provided by third party developers. The user input may be supplied to the framework via a host cmdlet.
