Internet-Draft The initial core schema for SCIM (System for Cross Identity Management) was designed for provisioning users. This memo specifies schema extensions that enables provisioning of devices, using various underlying bootstrapping systems, such as Wi-fi Easy Connect, FIDO device onboarding vouchers, BLE passcodes, and MAC authenticated bypass.

Introduction The Internet of Things presents a management challenge in many dimensions. One of them is the ability to onboard and manage large number of devices. There are many models for bootstrapping trust between devices and network deployments. Indeed it is expected that different manufacturers will make use of different methods. SCIM (System for Cross Identity Management) defines a protocol and a schema for provisioning of users. However, it can easily be extended to provision device credentials and other attributes into a network. The protocol and core schema were designed to permit just such extensions. Bulk operations are supported. This is good because often devices are procured in bulk. A primary purpose of this specification is to provision the network for onboarding and communications access to and from devices within a local deployment based on the underlying capabilities of those devices. The underlying security mechanisms of some devices range from non-existent such as the Bluetooth Low Energy (BLE) "Just Works" pairing method to a robust FIDO Device Onboard (FDO) mechanism. Information from the SCIM server is dispatched to control functions based on selected schema extensions to enable these communications within a network. The SCIM database is therefore essentially equivalent to a network's Authentication, Authorization, and Accounting (AAA) database, and should be carefully treated as such.

Why SCIM for devices? Some might ask why SCIM is well suited for this purpose and not, for example, NETCONF or RESTCONF with YANG . After all, there are all sorts of existing models available. The answer is that the only information being passed about the device is neither state nor device configuration information, but only information necessary to bootstrap trust so that the device may establish connectivity.

Protocol Participants In the normal SCIM model, it was presumed that large federated deployments would be SCIM clients who provision and remove employees and contractors as they enter and depart those deployments, and federated services such as sales, payment, or conferencing services would be the servers. In the device model, the roles are reversed, and may be somewhat more varied. A deployment network management system gateway (NMS gateway) plays the role of the server, receiving information about devices that are expected to be connected to its network. That server will apply appropriate local policies regarding whether/how the device should be connected. The client may be one of a number of entities: A vendor who is authorized to add devices to a network as part of a sales transaction. This is similar to the sales integration sometimes envisioned by Bootstrapping Remote Key Infrastructure (BRSKI) . A client application that administrators or employees use to add, remove, or get information about devices. An example might be an tablet or phone app that scans Wi-fi Easy Connect QR codes.

| SCIM | | | app |<-------------| Server | | +-----------+ Ctrl Endpt +---------+ | | | +-----------+ | +------------+ +-------+ | | Control |...........|..| ALG |.........|device | | | App | | +------------+ +-------+ | +-----------+ | | | | +-----------------------------------+ ]]>

In , the onboarding app provides the device particulars. As part of the response, the SCIM server might provide additional information, especially in the case of non-IP devices, where an application-layer gateway may need to be used to communicate with the device. The control endpoint is one among a number of objects that may be returned.

Schema Description RFC 7643 does not prescribe a language to describe a schema. We have chosen the JSON schema language for this purpose. The use of XML for SCIM devices is not supported. Several additional schemas specify specific onboarding mechanisms, such as BLE and Wi-fi Easy Connect.

Schema Representation Attributes defined in the device core schema and extensions comprise characteristics and SCIM datatypes defined in Sections 2.2 and 2.3 of the . This specifciation does not define new characteristics and datatypes for the SCIM attributes.

Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 when, and only when, they appear in all capitals, as shown here.

ResourceType Device A new resource type 'Device' is specified. The "ResourceType" schema specifies the metadata about a resource type (see section 6 of ). It comprises a core device schema and several extension schemas. The core schema provides a minimal resource representation, whereas extension schemas extend the core schema depending on the device's capability. The JSON schema for Device resource type is in .

Common Attributes The Device schema contains three common attributes as defined in the . id An id is a required and unique attribute of the device core schema (see section 3.1 of ). externalID An externalID is an optional attribute (see section 3.1 of ). meta Meta is a complex attribute and is required (see section 3.1 of ).

SCIM Core Device Schema The core device schema provides the minimal representation of a resource "Device". It contains only those attributes that any device may need, and only one attribute is required. The core schema for "Device" is identified using the schema URI: "urn:ietf:params:scim:schemas:core:2.0:Device". The following attributes are defined in the device core schema.

Singular Attributes displayName This attribute is of type "string" and provides a human-readable name for a device. It is intended to be displayed to end-users and should be suitable for that purpose. The attribute is not required, and is not case-sensitive. It may be modified and SHOULD be returned by default. No uniqueness constraints are imposed on this attribute. active The "active" attribute is of type "boolean" and is a mutable attribute, and is required. If set to TRUE, it means that this device is intended to be operational. Attempts to control or access a device where this value is set to FALSE may fail. For example, when used in conjunction with NIPC , commands such as connect, disconnect, subscribe that control app sends to the controller for the devices any command coming from the control app for the device will be rejected by the controller. mudUrl The mudUrl attribute represents the URL to the MUD file associated with this device. This attribute is optional and mutable. The mudUrl value is case sensitive and not unique. When present, this attribute may be used as described in . This attribute is case sensitive and returned by default. Attribute Multi Value Req Case Exact Mutable Return Unique displayName F F F RW Def None active F T F RW Def None mudUrl F F T RW Def None An example of a device SCIM object is as follows:

{ "schemas": ["urn:ietf:params:scim:schemas:core:2.0:Device"], "id": "e9e30dba-f08f-4109-8486-d5c6a3316111", "displayName": "BLE Heart Monitor", "active": true, "meta": { "resourceType": "Device", "created": "2022-01-23T04:56:22Z", "lastModified": "2022-05-13T04:42:34Z", "version": "W\/\"a330bc54f0671c9\"", "location": "https://example.com/v2/Device/e9e30dba-f08f -4109-8486-d5c6a3316111" } } ]]>

The schema for the device is presented in JSON format in Section , while the openAPI representation is provided in Section .

Device Groups Device groups are created using the SCIM groups as defined in Section 4.2.

Resource Type EndpointApp This section defines a new resource type, 'EndpointApp'. The "ResourceType" schema specifies the metadata about a resource type (see section 6 of ). The resource "EndpointApp" represents client applications that can control and/or receive data from the devices. The JSON schema for EndpointApp resource type is in . The attributes comprising EndpointsApp are listed in . The "EndpointApp" are included in the endpoint applications extension ("endpointAppsExt") .

SCIM EndpointApp Schema The EndpointApp schema is used to authorize clients control or telemetry services for clients. The schema identifies the application and how clients are to authenticate to the various services. The schema for "EndpointApp" is identified using the schema URI: "urn:ietf:params:scim:schemas:core:2.0:EndpointApp". The following attributes are defined in this schema.

Common Attributes The EndpointApp schema contains three common attributes as defined in the .

Singular Attributes applicationType This attribute is of type "string" and represents the type of application. It will only contain two values; 'deviceControl' or 'telemetry'. 'deviceControl' is the application that sends commands to control the device. 'telemetry' is the application that receives data from the device. The attribute is required, and is not case-sensitive. The attribute is readOnly and should be returned by default. No uniqueness constraints are imposed on this attribute. applicationName The "applicationName" attribute is of type "string" and represents a human readable name for the application. This attribute is required and mutable. The attribute should be returned by default and there is no uniqueness contraint on the attribute. clientToken This attribute type string contains a token that the client will use to authenticate itself. Each token may be a string up to 500 characters in length. It is not mutable, read-only, generated if no certificateInfo object is provisioned, case sensitive and returned by default if it exists. The SCIM server should expect that client tokens will be shared by the SCIM client with other components within the client's infrastructure.

Complex Attributes

certificateInfo It is the complex attribute that contains x509 certificate's subject name and root CA information associated with application clients that will connect for purposes of device control or telemetry. rootCA This is the base64 encoding a trust anchor certificate as described in Section 4. This trust anchor is applicable for certificates used for client application access. The object is not required, singular, case sensitive, and read/write. If not present, a set of trust anchors MUST be configured out of band. subjectName If present, this field may contain one of two names: a distinguished name as that will be present in the certificate subject field, as de scribed in Section 4.1.2.4 of ; or or a dnsName as part of a subjectAlternateName as described in Section 4.2.1.6 of . In the latter case, servers validating such certificates SHALL reject connections when name of the peer as resolved by a DNS reverse lookup does not match the dnsName in the certificate. If multiple dnsNames are present, it is left to server implementations to address any authorization conflicts associated with those names. This attribute is not required, read write, singular and NOT case sensitive. Attribute Multi Value Req Case Exact Mutable Return Unique applicationType F T F R Def None applicationName F T F RW Def None clientToken F F T R N None certificateInfo F F F RW Def None rootCA F F T RW Def None subjectName F T T RW Def None Note that either clientToken and certificateInfo are used for the authentication of the application. If certificateInfo is NOT present when an endpointApp is object created, then the server SHOULD return a clientToken. Otherwise, if the server accepts the certificateInfo object for authentication, it SHOULD NOT return a clientToken. If the server accepts and produces a clientToken, then control and telemetry servers MUST validate both. The SCIM client will know that this is the case based on the SCIM object that is returned. certificateInfo is preferred in situations where client functions are federated such that different clients may connect for different purposes.

SCIM Device Extensions SCIM provides various extension schemas, their attributes, JSON representation, and example object. The core schema is extended with a new resource type, as described in . No schemaExtensions list is specified in that definition. Instead, an IANA registry is created, where all values for "required" are set to false. All extensions to the Device schema MUST be registered via IANA, as described in . The schemas below demonstrate how this model is to work.

BLE Extension This schema extends the device schema to represent the devices supporting BLE. The extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:ble:2.0:Device The attributes are as follows:

Singular Attributes deviceMacAddress A string value that represent a public MAC address assigned by the manufacturer. It is a unique 48-bit value. Ir is required, case insensitive, and it is mutable and return as default. The regex pattern is the following:

isRandom A boolean flag taken from the BLE core specification, 5.3. If FALSE, the device is using a public MAC address. If TRUE, the device uses a random address. If an Idenifying Resolving Key (IRK) is present, the address represents a resolvable private address. Otherwise, the address is assumed to be a random static address. Non-resolvable private addresses are not supported by this specification. This attribute is not required. It is mutable, and is returned by default. The default value is FALSE. separateBroadcastAddress When present, this address is used for broadcasts/advertisements. This value MUST NOT be set when an IRK is provided. Its form is the same as deviceMacAddress. It is not required, multivalued, mutable, and returned by default. irk A string value that specifies the identity resolving key (IRK), which is unique to each device. It is used to resolve private random address. It should only be provisioned when isRandom is TRUE. It is mutable and never returned. For more information about the use of the IRK, see Section 5.4.5 of . mobility A boolean attribute to enable BLE device mobility. If set to TRUE, the device could be expected to move within a network of APs. For example, BLE device is connected with AP-1 and moves out of range but comes in range of AP-2, it will be disconnected with AP-1 and connects with AP-2. It is returned by default and mutable.

Multivalued Attributes versionSupport A multivalued attribute that provides all the BLE versions supported by the device in the form of an array. For example, [4.1, 4.2, 5.0, 5.1, 5.2, 5.3]. It is required, mutable, and return as default. pairingMethods An array of pairing methods associated with the BLE device. The pairing methods may require sub-attributes, such as key/password, for the device pairing process. To enable the scalability of pairing methods in the future, they are represented as extensions to incorporate various attributes that are part of the respective pairing process. Pairing method extensions are nested inside the BLE extension. It is required, case sensitive, mutable, and returned by default.

BLE Pairing Method Extensions The details on pairing methods and their associated attributes are in section 2.3 of . This memo defines extensions for four pairing methods that are nested insided the BLE extension schema. Each extension contains the common attributes . These extension are as follows: (i) pairingNull extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:pairingNull:2.0:Device pairingNull does not have any attribute. It allows pairing for BLE devices that do not require a pairing method. (ii) pairingJustWorks extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:pairingJustWorks:2.0:Device Just works pairing method does not require a key to pair devices. For completeness, the key attribute is included and is set to 'null'. Key attribute is required, immutable, and returned by default. (iii) pairingPassKey extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:pairingPassKey:2.0:Device The passkey pairing method requires a 6-digit key to pair devices. This extension has one singular integer attribute, "key", which is required, mutable and returned by default. The key pattern is as follows:

(iv) pairingOOB extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:pairingOOB:2.0:Device The out-of-band pairing method includes three singular attributes, i.e., key, randomNumber, and confirmationNumber. key The key is string value, required and received from out-of-bond sources such as NFC. It is case sensitive, mutable, and returned by default. randomNumber This attribute represents a nonce added to the key. It is an integer value that is a required attribute. It is mutable and returned by default. confirmationNumber An integer which some solutions require in RESTful message exchange. It is not required. It is mutable and returned by default if it exists. Attribute Multi Value Req Case Exact Mutable Return Unique deviceMacAddress F T F RW Def Manuf isRandom F T F RW Def None sepBroadcastAdd T F F RW Def None irk F F F WO Nev Manuf versionSupport T T F RW Def None mobility F F F RW Def None pairingMethods T T T RW Def None An example of a device object with BLE extension is as follows:

{ "schemas": ["urn:ietf:params:scim:schemas:core:2.0:Device", "urn:ietf:params:scim:schemas:extension:ble:2.0:Device"], "id": "e9e30dba-f08f-4109-8486-d5c6a3316111", "displayName": "BLE Heart Monitor", "active": true, "urn:ietf:params:scim:schemas:extension:ble:2.0:Device" : { "versionSupport": ["5.3"], "deviceMacAddress": "2C:54:91:88:C9:E2", "isRandom": false, "separateBroadcastAddress": ["AA:BB:88:77:22:11", "AA:BB:88:77 :22:12"], "mobility": true, "pairingMethods": ["urn:ietf:params:scim:schemas:extension :pairingPassKey:2.0:Device"], "urn:ietf:params:scim:schemas:extension:pairingPassKey:2.0 :Device" : { "key": 123456 } }, "meta": { "resourceType": "Device", "created": "2022-01-23T04:56:22Z", "lastModified": "2022-05-13T04:42:34Z", "version": "W\/\"a330bc54f0671c9\"", "location": "https://example.com/v2/Device/e9e30dba-f08f-4109 -8486-d5c6a3316111" } } ]]>

In the above example, the pairing method is "pairingPassKey", which implies that this BLE device pairs using only a passkey. In another example below, the pairing method is "pairingOOB", denoting that this BLE device uses the out-of-band pairing method.

{ "schemas": ["urn:ietf:params:scim:schemas:core:2.0:Device", "urn:ietf:params:scim:schemas:extension:ble:2.0:Device"], "id": "e9e30dba-f08f-4109-8486-d5c6a3316111", "displayName": "BLE Heart Monitor", "active": true, "urn:ietf:params:scim:schemas:extension:ble:2.0:Device" : { "versionSupport": ["5.3"], "deviceMacAddress": "2C:54:91:88:C9:E2", "isRandom": false, "separateBroadcastAddress": ["AA:BB:88:77:22:11", "AA:BB:88:77 :22:12"], "mobility": true, "pairingMethods": ["urn:ietf:params:scim:schemas:extension :pairingOOB:2.0:Device"], "urn:ietf:params:scim:schemas:extension:pairingOOB:2.0:Device": { "key": "TheKeyvalueRetrievedFromOOB", "randomNumber": 238796813516896 } }, "meta": { "resourceType": "Device", "created": "2022-01-23T04:56:22Z", "lastModified": "2022-05-13T04:42:34Z", "version": "W\/\"a330bc54f0671c9\"", "location": "https://example.com/v2/Device/e9e30dba-f08f-4109 -8486-d5c6a3316111" } } ]]>

However, a device can have more than one pairing method. Support for multiple pairing methods is also provided by the multi-valued attribute pairingMethods. In the example below, the BLE device can pair with both passkey and OOB pairing methods.

The Endpoint Applications Extension Schema Sometimes non-IP devices such as those using BLE or Zigbee require an application gateway interface to manage them. SCIM clients MUST NOT specify this to describe native IP-based devices. endpointAppsExt provides the list application that connect to enterprise gateway. The endpointAppsExt has one multivalued attribute and two singular attributes. The extension is identified using the following schema URI: urn:ietf:params:scim:schemas:extension:endpointAppsExt:2.0:Device

Singular Attributes deviceControlEnterpriseEndpoint Device control apps use this URL of the enterprise endpoint to reach the enterprise gateway. When the enterprise receives the SCIM object from the onboarding app, it adds this attribute to it and sends it back as a response to the onboarding app. This attribute is required, case-sensitive, mutable, and returned by default. The uniqueness is enforced by the enterprise. telemetryEnterpriseEndpoint Telemetry apps use this URL of the enterprise endpoint to reach the enterprise gateway. When the enterprise receives the SCIM object from the onboarding app, it adds this attribute to it and sends it back as a response to the onboarding app. This attribute is optional, case-sensitive, mutable, and returned by default. The uniqueness is enforced by the enterprise. An implementation MUST generate an exception if telemetryEnterpriseEndpoint is not returned and telemetry is required for the proper functioning of a device.

Multivalued Attribute applications This is a complex multivalued attribute. It represents a list of endpoint applications i.e., deviceControl and telemetry. Each entry in the list comprises two attributes including "value" and "$ref". value It is the identifier of the endpoint application formated as UUID. It is same as the common attribute "$id" of the resource "endpointApp". It is read/write, required, case insensitive and returned by default. $ref It is the reference to the respective endpointApp resource object stored in the SCIM server. It is readOnly, required, case sensitive and returned by default.

Security Considerations Because provisioning operations are sensitive, each client must be appropriately authenticated. Certain objects may be read-only or not visible based on who is connected.

SCIM operations An attacker that has authenticated to a trusted SCIM client could manipulate portions of the SCIM database. To be clear on the risks, we discuss each operation below:

Object Creation Object creation in this framework grants a device access to the infrastructure and will to a greater or lesser extent grant the infrastructure access to the device. When IP-layer access is provisioned, then the access will be at the IP layer. For non-IP layer access, such as provisioning of BLE devices, the access may be to the entire device. The explicit grant is made when the credentials of the device are shared with the SCIM server.

Object Deletion Once granted, even if the object is removed, the server may or may not act on that removal. The deletion of the object is a signal of intent by the application that it no longer expects the device to be on the network. It is strictly up to the SCIM server and its back end policy to decide whether or not to revoke access to the infrastructure. Any access grant by the device must be separately handled.

Read operations Read operations are necessary in order for an application to sync its state to know what devices it is expected to manage. An attacker with access to SCIM objects may gain access to the devices themselves. To prevent one SCIM client from interfering with devices that it has no business managing, only clients that have created objects or those they authorize SHOULD have the ability to read those objects.

Update Operations Update operations may be necessary if a device has been modified in some way. Attackers with update access may be able to disable network access to devices or device access to networks. To avoid this, the same access control policy for read operations is RECOMMENDED here.

Higher level protection for certain systems Devices provisioned with this model may be completely controlled by the administrator of the SCIM server, depending on how those systems are defined. For instance, if BLE passkeys are provided, the device can be connected to, and perhaps paired with. Any additional security must be provided at higher application layers. For example, if client applications wish to keep private information to and from the device, they should encrypt that information over-the-top.

Logging An attacker could learn what devices are on a network by examining SCIM logs. Due to the sensitive nature of SCIM operations, logs SHOILD be encrypted both on the disk and in transit.

IANA Considerations

New Schemas The IANA is requested to add the following additions to the "SCIM Schema URIs for Data Resources" registry as follows: URN Name Reference urn:ietf:params:scim:schemas:core: 2.0:Device Core Device Schema This memo, urn:ietf:params:scim:schemas:core: 2.0:EndpointApp Endpoint Application This memo, Note that the line break in URNs should be removed, as should this comment.

Device Schema Extensions IANA is requested to create a separate table for Device Schema Extensions, as described in , with the following columns: schemaExtensionURI Short Description Reference The policy for entries into this table shall be and "Specification Required", as specified in . Designated experts shall check that each schema is produced in the format described in , and that the semantics of the schema are clear and unambiguous. It is also RECOMMENDED that schemas be made available in OpenAPI. The initial table entries shall be as follows: URN Description Reference urn:ietf:params:scim:schemas:extension: ble:2.0:Device BLE Extension This memo, urn:ietf:params:scim:schemas:extension: ethernet-mab:2.0:Device Ethernet MAB This memo, urn:ietf:params:scim:schemas:extension: fido-device-onboard:2.0:Device FIDO Device Onboard This memo, urn:ietf:params:scim:schemas:extension: dpp:2.0:Device Wi-fi Easy Connect This memo, urn:ietf:params:scim:schemas:extension: endpointAppsExt:2.0:Device Application Endpoint Extension This memo, urn:ietf:params:scim:schemas:extension: pairingJustWorks:2.0:Device Just Works Auth BLE This memo, urn:ietf:params:scim:schemas:extension: pairingOOB:2.0:Device Out of Band Pairing for BLE This memo, urn:ietf:params:scim:schemas:extension: pairingPassKey:2.0:Device Passkey Pairing for BLE This memo,

Bluetooth SIG Wi-Fi Alliance FIDO Alliance The System for Cross-domain Identity Management (SCIM) specifications are designed to make identity management in cloud-based applications and services easier. The specification suite builds upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. Its intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model as well as binding documents to provide patterns for exchanging this schema using HTTP. This document provides a platform-neutral schema and extension model for representing users and groups and other resource types in JSON format. This schema is intended for exchange and use with cloud service providers. The System for Cross-domain Identity Management (SCIM) specification is an HTTP-based protocol that makes managing identities in multi-domain scenarios easier to support via a standardized service. Examples include, but are not limited to, enterprise-to-cloud service providers and inter-cloud scenarios. The specification suite seeks to build upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. SCIM's intent is to reduce the cost and complexity of user management operations by providing a common user schema, an extension model, and a service protocol defined by this document. Postman JSON Schema defines the media type "application/schema+json", a JSON- based format for describing the structure of JSON data. JSON Schema asserts what a JSON document must look like, ways to extract information from it, and how to interact with it. The "application/ schema-instance+json" media type provides additional feature-rich integration with "application/schema+json" beyond what can be offered for "application/json" documents. In many standards track documents several words are used to signify the requirements in the specification. These words are often capitalized. This document defines these words as they should be interpreted in IETF documents. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements. RFC 2119 specifies common key words that may be used in protocol specifications. This document aims to reduce the ambiguity by clarifying that only UPPERCASE usage of the key words have the defined special meanings. This memo specifies a component-based architecture for Manufacturer Usage Descriptions (MUDs). The goal of MUD is to provide a means for end devices to signal to the network what sort of access and network functionality they require to properly function. The initial focus is on access control. Later work can delve into other aspects. This memo specifies two YANG modules, IPv4 and IPv6 DHCP options, a Link Layer Discovery Protocol (LLDP) TLV, a URL, an X.509 certificate extension, and a means to sign and verify the descriptions. This document describes the commonly used base 64, base 32, and base 16 encoding schemes. It also discusses the use of line-feeds in encoded data, use of padding in encoded data, use of non-alphabet characters in encoded data, use of different encoding alphabets, and canonical encodings. [STANDARDS-TRACK] This memo profiles the X.509 v3 certificate and X.509 v2 certificate revocation list (CRL) for use in the Internet. An overview of this approach and model is provided as an introduction. The X.509 v3 certificate format is described in detail, with additional information regarding the format and semantics of Internet name forms. Standard certificate extensions are described and two Internet-specific extensions are defined. A set of required certificate extensions is specified. The X.509 v2 CRL format is described in detail along with standard and Internet-specific extensions. An algorithm for X.509 certification path validation is described. An ASN.1 module and examples are provided in the appendices. [STANDARDS-TRACK] Many protocols make use of points of extensibility that use constants to identify various protocol parameters. To ensure that the values in these fields do not have conflicting uses and to promote interoperability, their allocations are often coordinated by a central record keeper. For IETF protocols, that role is filled by the Internet Assigned Numbers Authority (IANA). To make assignments in a given registry prudently, guidance describing the conditions under which new values should be assigned, as well as when and how modifications to existing values can be made, is needed. This document defines a framework for the documentation of these guidelines by specification authors, in order to assure that the provided guidance for the IANA Considerations is clear and addresses the various issues that are likely in the operation of a registry. This is the third edition of this document; it obsoletes RFC 5226. The Network Configuration Protocol (NETCONF) defined in this document provides mechanisms to install, manipulate, and delete the configuration of network devices. It uses an Extensible Markup Language (XML)-based data encoding for the configuration data as well as the protocol messages. The NETCONF protocol operations are realized as remote procedure calls (RPCs). This document obsoletes RFC 4741. [STANDARDS-TRACK] This document describes an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF). YANG is a data modeling language used to model configuration data, state data, Remote Procedure Calls, and notifications for network management protocols. This document describes the syntax and semantics of version 1.1 of the YANG language. YANG version 1.1 is a maintenance release of the YANG language, addressing ambiguities and defects in the original specification. There are a small number of backward incompatibilities from YANG version 1. This document also specifies the YANG mappings to the Network Configuration Protocol (NETCONF). This document specifies automated bootstrapping of an Autonomic Control Plane. To do this, a Secure Key Infrastructure is bootstrapped. This is done using manufacturer-installed X.509 certificates, in combination with a manufacturer's authorizing service, both online and offline. We call this process the Bootstrapping Remote Secure Key Infrastructure (BRSKI) protocol. Bootstrapping a new device can occur when using a routable address and a cloud service, only link-local connectivity, or limited/disconnected networks. Support for deployment models with less stringent security requirements is included. Bootstrapping is complete when the cryptographic identity of the new key infrastructure is successfully deployed to the device. The established secure connection can be used to deploy a locally issued certificate to the device as well. Cisco Systems Cisco Systems Philips This memo specifies RESTful application layer interface for gateways providing operations against non-IP devices. The described interface is extensible. This memo initially describes Bluetooth Low Energy and Zigbee as they are the most commonly deployed.
