the Hypertext Transfer Protocol (HTTP) (as specified in [RFC2616]). It is used for getting a client's configuration and modules (1) from the server and for reporting back the client's status to the server.Sections 1.8, 2, and 3 of this specification are normative and can contain the terms MAY, SHOULD, MUST, MUST NOT, and SHOULD NOT as defined in [RFC2119]. Sections 1.5 and 1.9 are also normative but do not contain those terms. All other sections and examples in this specification are informative.Glossary XE "Glossary" The following terms are specific to this document:Augmented Backus-Naur Form (ABNF): A modified version of Backus-Naur Form (BNF), commonly used by Internet specifications. ABNF notation balances compactness and simplicity with reasonable representational power. ABNF differs from standard BNF in its definitions and uses of naming rules, repetition, alternatives, order-independence, and value ranges. For more information, see [RFC5234].binary large object (BLOB): A collection of binary data stored as a single entity in a database.checksum: A value that is the summation of a byte stream. By comparing the checksums computed from a data item at two different times, one can quickly assess whether the data items are identical.configuration: Represents a binary large object (BLOB). The protocol does not process the content of the BLOB and it is passed as-is to the higher layer.Hypertext Transfer Protocol (HTTP): An application-level protocol for distributed, collaborative, hypermedia information systems (text, graphic images, sound, video, and other multimedia files) on the World Wide Web.module: (1) A file used by a server to register and instantiate one or more components. It contains either implementations of the components or metadata that a server can use to find implementations.(2) A BLOB in the Desired State Configuration Pull Model Protocol [MS-DSCPM]. The protocol does not process the content of the BLOB, and it is passed as it is to the higher layer.Transmission Control Protocol (TCP): A protocol used with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. TCP handles keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.Uniform Resource Identifier (URI): A string that identifies a resource. The URI is an addressing mechanism defined in Internet Engineering Task Force (IETF) Uniform Resource Identifier (URI): Generic Syntax [RFC3986].Uniform Resource Locator (URL): A string of characters in a standardized format that identifies a document or resource on the World Wide Web. The format is as specified in [RFC1738].universally unique identifier (UUID): A 128-bit value. UUIDs can be used for multiple purposes, from tagging objects with an extremely short lifetime, to reliably identifying very persistent objects in cross-process communication such as client and server interfaces, manager entry-point vectors, and RPC objects. UUIDs are highly likely to be unique. UUIDs are also known as globally unique identifiers (GUIDs) and these terms are used interchangeably in the Microsoft protocol technical documents (TDs). Interchanging the usage of these terms does not imply or require a specific algorithm or mechanism to generate the UUID. Specifically, the use of this term does not imply or require that the algorithms described in [RFC4122] or [C706] must be used for generating the UUID.MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.ReferencesLinks to a document in the Microsoft Open Specifications library point to the correct section in the most recently published version of the referenced document. However, because individual documents in the library are not updated at the same time, the section numbers in the documents may not match.

In this specification, the entity that initiates the HTTP connection is referred to as the client, and the entity that responds to the HTTP connection is referred to as the server. With the Desired State Configuration Pull Model Protocol, binary data flows from the server to the client. Relationship to Other Protocols XE "Relationship to other protocols" XE "Relationship to other protocols"This protocol depends on HTTP as specified in [RFC2616]. HTTP version 1.1 is used with this protocol.Prerequisites/Preconditions XE "Prerequisites" XE "Preconditions" XE "Prerequisites" XE "Preconditions"This protocol does not provide a mechanism for a client to discover the Uniform Resource Locator (URL) of the server. Thus, it is a prerequisite that the client obtain the URL of the server before this protocol can be used.Applicability Statement XE "Applicability" XE "Applicability"The Desired State Configuration Pull Model Protocol is capable of downloading the configuration and modules from the server.This document covers versioning issues in the following areas:Supported Transports: This protocol can be implemented on top of HTTP, as specified in section 2.1.Security and Authentication Methods: This protocol supports HTTP access authentication, as specified in [RFC2616] section 11.

This approach works because the attacker can establish its own TCP connection to the server and send a request by using the victim's ConfigurationId, JobId, and/or ModuleName, ModuleVersion value. To mitigate the attack, ConfigurationId and JobId should be a random value. Also, if HTTP access authentication is used, the server should authenticate access at least once on each new URL or TCP connection.Index of Security Parameters XE "Security:parameter index" XE "Index of security parameters" XE "Parameters - security index" XE "Security:parameter index"Security parameterSectionHTTP access authenticationAs specified in section 2.1.Appendix A: Full JSON Schema XE "JSON schema" XE "Full JSON schema" XE "Schema - JSON" XE "JSON schema"{ "title": "GetAction request schema", "type" : "object", "properties": { "Checksum": { "type": ["string","null"] }, "ConfigurationName": { "type": ["string","null"] }, "NodeCompliant": { "type": "boolean" }, "ChecksumAlgorithm": { "enum": ["SHA-256"], "description": "Checksum algorithm used to generate checksum" } }, "required": ["Checksum", "NodeCompliant", "ChecksumAlgorithm"]}{ "title": "GetAction response", "type": "object", "properties": { "value": { "enum": ["OK", "GetConfiguration", "Retry"], "required": "true" } }} Appendix B: Product Behavior XE "Product behavior" The information in this specification is applicable to the following Microsoft products or supplemental software.
