IANA expert review comments | LGTM. Same comment as for SSH with the naming choices. Separately, the descriptions of TLS ciphersuites, which I assume are just free-form strings, do not match those in the registry, which seems unwise. I get that you might need to translate '_' into '-' for YANG identifiers, but that seems gratuitous for descriptions. | ||

NETCONF Working Group K. Watsen Internet-Draft Watsen Networks Intended status: Standards Track 16 March 2024 Expires: 17 September 2024 YANG Groupings for TLS Clients and TLS Servers draft-ietf-netconf-tls-client-server-41 Abstract This document presents four YANG 1.1 modules. Three IETF modules, and one supporting IANA module. The three IETF modules are: ietf-tls-common, ietf-tls-client, and ietf-tls-server. The "ietf-tls-client" and "ietf-tls-server" modules are the primary productions of this work, supporting the configuration and monitoring of TLS clients and servers. The IANA module is: iana-tls-cipher-suite-algs. This module defines YANG enumerations providing support for an IANA-maintained algorithm registry. Editorial Note (To be removed by RFC Editor) This draft contains placeholder values that need to be replaced with finalized values at the time of publication. This note summarizes all of the substitutions that are needed. No other RFC Editor instructions are specified elsewhere in this document. Artwork in this document contains shorthand references to drafts in progress. Please apply the following replacements: * AAAA --> the assigned RFC value for draft-ietf-netconf-crypto- types * BBBB --> the assigned RFC value for draft-ietf-netconf-trust- anchors * CCCC --> the assigned RFC value for draft-ietf-netconf-keystore * DDDD --> the assigned RFC value for draft-ietf-netconf-tcp-client- server * FFFF --> the assigned RFC value for this draft Artwork in this document contains placeholder values for the date of publication of this draft. Please apply the following replacement: Watsen Expires 17 September 2024 [Page 1] Internet-Draft Groupings for TLS Clients and Servers March 2024 * 2024-03-16 --> the publication date of this draft The "Relation to other RFCs" section Section 1.2 contains the text "one or more YANG modules" and, later, "modules". This text is sourced from a file in a context where it is unknown how many modules a draft defines. The text is not wrong as is, but it may be improved by stating more directly how many modules are defined. The "Relation to other RFCs" section Section 1.2 contains a self- reference to this draft, along with a corresponding reference in the Appendix. Please replace the self-reference in this section with "This RFC" (or similar) and remove the self-reference in the "Normative/Informative References" section, whichever it is in. Tree-diagrams in this draft may use the '\' line-folding mode defined in RFC 8792. However, nicer-to-the-eye is when the '\\' line-folding mode is used. The AD suggested suggested putting a request here for the RFC Editor to help convert "ugly" '\' folded examples to use the '\\' folding mode. "Help convert" may be interpreted as, identify what looks ugly and ask the authors to make the adjustment. The following Appendix sections are to be removed prior to publication: * Appendix A.1. Initial Module for the "TLS Cipher Suites" Registry * Appendix B. Change Log Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Introduction This document presents four YANG 1.1 [RFC7950] modules. Three "IETF" modules and one "IANA" module. The three IETF modules are ietf-tls-common (Section 2), ietf-tls- client (Section 3), and ietf-tls-server (Section 4). The "ietf-tls- client" and "ietf-tls-server" modules are the primary productions of this work, supporting the configuration and monitoring of TLS clients and servers. The groupings defined in this document are expected to be used in conjunction with the groupings defined in an underlying transport- level module, such as the groupings defined in [I-D.ietf-netconf-tcp-client-server]. The transport-level data model enables the configuration of transport-level values such as a remote address, a remote port, a local address, and a local port. The IANA module is iana-tls-cipher-suite-algs (Appendix A.1). This module defines YANG enumerations providing support for an IANA- maintained algorithm registry. This document assumes that the IANA module exists, and presents a script in Appendix A that IANA may use to generate the YANG module. This document does not publish initial version of this module. IANA publishes this module. 1.1. Regarding the IETF Modules The three IETF modules define features and groupings to model "generic" TLS clients and TLS servers, where "generic" should be interpreted as "least common denominator" rather than "complete." Basic TLS protocol support is afforded by these modules, leaving configuration of advance features to augmentations made by consuming modules. It is intended that the YANG groupings will be used by applications needing to configure TLS client and server protocol stacks. For instance, these groupings are used to help define the data model for HTTPS [RFC2818] and NETCONF over TLS [RFC7589] based clients and servers in [I-D.ietf-netconf-http-client-server] and [I-D.ietf-netconf-netconf-client-server] respectively. The ietf-tls-client and ietf-tls-server YANG modules each define one grouping, which is focused on just TLS-specific configuration, and specifically avoids any transport-level configuration, such as what ports to listen-on or connect-to. This affords applications the opportunity to define their own strategy for how the underlying TCP Watsen Expires 17 September 2024 [Page 5] Internet-Draft Groupings for TLS Clients and Servers March 2024 connection is established. For instance, applications supporting NETCONF Call Home [RFC8071] could use the "tls-server-grouping" grouping for the TLS parts it provides, while adding data nodes for the TCP-level call-home configuration. Both TLS 1.2 and TLS 1.3 may be configured. TLS 1.2 [RFC5246] is obsoleted by TLS 1.3 [RFC8446] but still in common use, and hence its "feature" statement is marked "status deprecated". 1.2. Relation to other RFCs This document presents one or more YANG modules [RFC7950] that are part of a collection of RFCs that work together to, ultimately, support the configuration of both the clients and servers of both the NETCONF [RFC6241] and RESTCONF [RFC8040] protocols. The dependency relationship between the primary YANG groupings defined in the various RFCs is presented in the below diagram. In some cases, a draft may define secondary groupings that introduce dependencies not illustrated in the diagram. The labels in the diagram are a shorthand name for the defining RFC. The citation reference for shorthand name is provided below the diagram. Please note that the arrows in the diagram point from referencer to referenced. For example, the "crypto-types" RFC does not have any dependencies, whilst the "keystore" RFC depends on the "crypto-types" RFC.

Specification Language 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 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 1.4. Adherence to the NMDA This document is compliant with the Network Management Datastore Architecture (NMDA) [RFC8342]. For instance, as described in [I-D.ietf-netconf-trust-anchors] and [I-D.ietf-netconf-keystore], trust anchors and keys installed during manufacturing are expected to appear in <operational> (Section 5.3 of [RFC8342]), and <system> [I-D.ietf-netmod-system-config], if implemented. 1.5. Conventions Various examples in this document use "BASE64VALUE=" as a placeholder value for binary data that has been base64 encoded (per Section 9.8 of [RFC7950]). This placeholder value is used because real base64 encoded structures are often many lines long and hence distracting to the example being presented. 2. The "ietf-tls-common" Module The TLS common model presented in this section contains features and groupings common to both TLS clients and TLS servers. The "hello- params-grouping" grouping can be used to configure the list of TLS algorithms permitted by the TLS client or TLS server. The lists of algorithms are ordered such that, if multiple algorithms are permitted by the client, the algorithm that appears first in its list that is also permitted by the server is used for the TLS transport layer connection. The ability to restrict the algorithms allowed is provided in this grouping for TLS clients and TLS servers that are capable of doing so and may serve to make TLS clients and TLS servers compliant with local security policies. This model supports both TLS 1.2 [RFC5246] and TLS 1.3 [RFC8446]. Thus, in order to support both TLS1.2 and TLS1.3, the cipher-suites part of the "hello-params-grouping" grouping should include three parameters for configuring its permitted TLS algorithms, which are: TLS Cipher Suites, TLS SignatureScheme, TLS Supported Groups. Watsen Expires 17 September 2024 [Page 8] Internet-Draft Groupings for TLS Clients and Servers March 2024 2.1. Data Model Overview This section provides an overview of the "ietf-tls-common" module in terms of its features, identities, and groupings. 2.1.1. Features The following diagram lists all the "feature" statements defined in the "ietf-tls-common" module: Features: +-- tls12 +-- tls13 +-- hello-params +-- asymmetric-key-pair-generation +-- supported-algorithms The diagram above uses syntax that is similar to but not defined in [RFC8340]. Please refer to the YANG module for a description of each feature. 2.1.2. Identities The following diagram illustrates the relationship amongst the "identity" statements defined in the "ietf-tls-common" module: Identities: +-- tls-version-base +-- tls12 +-- tls13 The diagram above uses syntax that is similar to but not defined in [RFC8340]. Comments: * The diagram shows that there are two base identities. * One base identity is used to specific TLS versions, while the other is used to specify cipher-suites. * These base identities are "abstract", in the object oriented programming sense, in that they only define a "class" of things, rather than a specific thing. 2.1.3. Groupings The "ietf-tls-common" module defines the following "grouping" statement: Watsen Expires 17 September 2024 [Page 9] Internet-Draft Groupings for TLS Clients and Servers March 2024 * hello-params-grouping This grouping is presented in the following subsection. 2.1.3.1. The "hello-params-grouping" Grouping The following tree diagram [RFC8340] illustrates the "hello-params- grouping" grouping: grouping hello-params-grouping: +-- tls-versions | +-- min? identityref | +-- max? identityref +-- cipher-suites +-- cipher-suite* tlscsa:tls-cipher-suite-algorithm Comments: * This grouping is used by both the "tls-client-grouping" and the "tls-server-grouping" groupings defined in Section 3.1.2.1 and Section 4.1.2.1, respectively. * This grouping enables client and server configurations to specify the TLS versions and cipher suites that are to be used when establishing TLS sessions. * The "cipher-suites" list is "ordered-by user". 2.1.4. Protocol-accessible Nodes The following tree diagram [RFC8340] lists all the protocol- accessible nodes defined in the "ietf-tls-common" module, without expanding the "grouping" statements: Watsen Expires 17 September 2024 [Page 10] Internet-Draft Groupings for TLS Clients and Servers March 2024 module: ietf-tls-common +--ro supported-algorithms {algorithm-discovery}? +--ro supported-algorithm* tlscsa:tls-cipher-suite-algorithm rpcs: +---x generate-asymmetric-key-pair {asymmetric-key-pair-generation}? +---w input | +---w algorithm | | tlscsa:tls-cipher-suite-algorithm | +---w num-bits? uint16 | +---w private-key-encoding | +---w (private-key-encoding) | +--:(cleartext) {ct:cleartext-private-keys}? | | +---w cleartext? empty | +--:(encrypted) {ct:encrypted-private-keys}? | | +---w encrypted | | +---w ks:encrypted-by-grouping | +--:(hidden) {ct:hidden-private-keys}? | +---w hidden? empty +--ro output +--ro (key-or-hidden)? +--:(key) | +---u ct:asymmetric-key-pair-grouping +--:(hidden) +--ro location? instance-identifier Comments: * Protocol-accessible nodes are those nodes that are accessible when the module is "implemented", as described in Section 5.6.5 of [RFC7950]. * The protocol-accessible nodes for the "ietf-tls-common" module are limited to the "supported-algorithms" container, which is constrained by the "algorithm-discovery" feature, and the RPC "generate-asymmetric-key-pair", which is constrained by the "asymmetric-key-pair-generation" feature. * The "encrypted-by-grouping" grouping is discussed in Section 2.1.3.1 of [I-D.ietf-netconf-keystore]. * The "asymmetric-key-pair-grouping" grouping is discussed in Section 2.1.4.6 of [I-D.ietf-netconf-crypto-types].

The "ietf-tls-client" Module This section defines a YANG 1.1 [RFC7950] module called "ietf-tls- client". A high-level overview of the module is provided in Section 3.1. Examples illustrating the module's use are provided in Examples (Section 3.2). The YANG module itself is defined in Section 3.3. 3.1. Data Model Overview This section provides an overview of the "ietf-tls-client" module in terms of its features and groupings. 3.1.1. Features The following diagram lists all the "feature" statements defined in the "ietf-tls-client" module: Watsen Expires 17 September 2024 [Page 21] Internet-Draft Groupings for TLS Clients and Servers March 2024 Features: +-- tls-client-keepalives +-- client-ident-x509-cert +-- client-ident-raw-public-key +-- client-ident-psk +-- server-auth-x509-cert +-- server-auth-raw-public-key +-- server-auth-psk The diagram above uses syntax that is similar to but not defined in [RFC8340]. Please refer to the YANG module for a description of each feature. 3.1.2. Groupings The "ietf-tls-client" module defines the following "grouping" statement: * tls-client-grouping This grouping is presented in the following subsection. 3.1.2.1. The "tls-client-grouping" Grouping The following tree diagram [RFC8340] illustrates the "tls-client- grouping" grouping: Watsen Expires 17 September 2024 [Page 22] Internet-Draft Groupings for TLS Clients and Servers March 2024 =============== NOTE: '\' line wrapping per RFC 8792 ================ grouping tls-client-grouping: +-- client-identity! | +-- (auth-type) | +--:(certificate) {client-ident-x509-cert}? | | +-- certificate | | +---u ks:inline-or-keystore-end-entity-cert-with-key\ -grouping | +--:(raw-public-key) {client-ident-raw-public-key}? | | +-- raw-private-key | | +---u ks:inline-or-keystore-asymmetric-key-grouping | +--:(tls12-psk) {client-ident-tls12-psk}? | | +-- tls12-psk | | +---u ks:inline-or-keystore-symmetric-key-grouping | | +-- id? | | string | +--:(tls13-epsk) {client-ident-tls13-epsk}? | +-- tls13-epsk | +---u ks:inline-or-keystore-symmetric-key-grouping | +-- external-identity | | string | +-- hash? | | tlscmn:epsk-supported-hash | +-- context? | | string | +-- target-protocol? | | uint16 | +-- target-kdf? | uint16 +-- server-authentication | +-- ca-certs! {server-auth-x509-cert}? | | +---u ts:inline-or-truststore-certs-grouping | +-- ee-certs! {server-auth-x509-cert}? | | +---u ts:inline-or-truststore-certs-grouping | +-- raw-public-keys! {server-auth-raw-public-key}? | | +---u ts:inline-or-truststore-public-keys-grouping | +-- tls12-psks? empty {server-auth-tls12-psk}? | +-- tls13-epsks? empty {server-auth-tls13-epsk}? +-- hello-params {tlscmn:hello-params}? | +---u tlscmn:hello-params-grouping +-- keepalives {tls-client-keepalives}? +-- peer-allowed-to-send? empty +-- test-peer-aliveness! +-- max-wait? uint16 +-- max-attempts? uint8 Comments: Watsen Expires 17 September 2024 [Page 23] Internet-Draft Groupings for TLS Clients and Servers March 2024 * The "client-identity" node, which is optionally configured (as client authentication MAY occur at a higher protocol layer), configures identity credentials, each enabled by a "feature" statement defined in Section 3.1.1. * The "server-authentication" node configures trust anchors for authenticating the TLS server, with each option enabled by a "feature" statement. * The "hello-params" node, which must be enabled by a feature, configures parameters for the TLS sessions established by this configuration. * The "keepalives" node, which must be enabled by a feature, configures a "presence" container for testing the aliveness of the TLS server. The aliveness-test occurs at the TLS protocol layer. * For the referenced grouping statement(s): - The "inline-or-keystore-end-entity-cert-with-key-grouping" grouping is discussed in Section 2.1.3.6 of [I-D.ietf-netconf-keystore]. - The "inline-or-keystore-asymmetric-key-grouping" grouping is discussed in Section 2.1.3.4 of [I-D.ietf-netconf-keystore]. - The "inline-or-keystore-symmetric-key-grouping" grouping is discussed in Section 2.1.3.3 of [I-D.ietf-netconf-keystore]. - The "inline-or-truststore-certs-grouping" grouping is discussed in Section 2.1.3.3 of [I-D.ietf-netconf-trust-anchors]. - The "inline-or-truststore-public-keys-grouping" grouping is discussed in Section 2.1.3.4 of [I-D.ietf-netconf-trust-anchors]. - The "hello-params-grouping" grouping is discussed in Section 2.1.3.1 in this document. 3.1.3. Protocol-accessible Nodes The "ietf-tls-client" module defines only "grouping" statements that are used by other modules to instantiate protocol-accessible nodes. Thus this module, when implemented, does not itself define any protocol-accessible nodes.

These examples are effectively the same except the first configures the client identity using a local key while the second uses a key configured in a keystore. Both examples are consistent with the examples presented in Section 2.2.1 of [I-D.ietf-netconf-trust-anchors] and Section 2.2.1 of [I-D.ietf-netconf-keystore].

The "ietf-tls-server" Module This section defines a YANG 1.1 module called "ietf-tls-server". A high-level overview of the module is provided in Section 4.1. Examples illustrating the module's use are provided in Examples (Section 4.2). The YANG module itself is defined in Section 4.3. 4.1. Data Model Overview This section provides an overview of the "ietf-tls-server" module in terms of its features and groupings. 4.1.1. Features The following diagram lists all the "feature" statements defined in the "ietf-tls-server" module: Features: +-- tls-server-keepalives +-- server-ident-x509-cert +-- server-ident-raw-public-key +-- server-ident-psk +-- client-auth-supported +-- client-auth-x509-cert +-- client-auth-raw-public-key +-- client-auth-psk The diagram above uses syntax that is similar to but not defined in [RFC8340]. Please refer to the YANG module for a description of each feature. 4.1.2. Groupings The "ietf-tls-server" module defines the following "grouping" statement: * tls-server-grouping Watsen Expires 17 September 2024 [Page 39] Internet-Draft Groupings for TLS Clients and Servers March 2024 This grouping is presented in the following subsection. 4.1.2.1.

The aliveness-tests occurs at the TLS protocol layer. * For the referenced grouping statement(s): - The "inline-or-keystore-end-entity-cert-with-key-grouping" grouping is discussed in Section 2.1.3.6 of [I-D.ietf-netconf-keystore]. - The "inline-or-keystore-asymmetric-key-grouping" grouping is discussed in Section 2.1.3.4 of [I-D.ietf-netconf-keystore]. - The "inline-or-keystore-symmetric-key-grouping" grouping is discussed in Section 2.1.3.3 of [I-D.ietf-netconf-keystore]. - The "inline-or-truststore-public-keys-grouping" grouping is discussed in Section 2.1.3.4 of [I-D.ietf-netconf-trust-anchors]. - The "inline-or-truststore-certs-grouping" grouping is discussed in Section 2.1.3.3 of [I-D.ietf-netconf-trust-anchors]. - The "hello-params-grouping" grouping is discussed in Section 2.1.3.1 in this document. 4.1.3. Protocol-accessible Nodes The "ietf-tls-server" module defines only "grouping" statements that are used by other modules to instantiate protocol-accessible nodes. Thus this module, when implemented, does not itself define any protocol-accessible nodes. Watsen Expires 17 September 2024 [Page 42] Internet-Draft Groupings for TLS Clients and Servers March 2024 4.2. Example Usage This section presents two examples showing the "tls-server-grouping" grouping populated with some data. These examples are effectively the same except the first configures the server identity using a local key while the second uses a key configured in a keystore. Both examples are consistent with the examples presented in Section 2.2.1 of [I-D.ietf-netconf-trust-anchors] and Section 2.2.1 of [I-D.ietf-netconf-keystore].

Security Considerations The three IETF YANG modules in this document define groupings and will not be deployed as standalone modules. Their security implications may be context dependent based on their use in other modules. The designers of modules which import these grouping must conduct their own analysis of the security considerations. 5.1. Considerations for the "iana-tls-cipher-suite-algs" Module This section follows the template defined in Section 3.7.1 of [RFC8407]. The "iana-tls-cipher-suite-algs" YANG module defines a data model that is designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication. The Network Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular users to a pre-configured subset of all available protocol operations and content. This YANG module defines YANG enumerations, for a public IANA- maintained registry. YANG enumerations are not security-sensitive, as they are statically defined in the publicly-accessible YANG module. IANA MAY deprecate and/or obsolete enumerations over time as needed to address security issues found in the algorithms. This module does not define any writable-nodes, RPCs, actions, or notifications, and thus the security consideration for such is not provided here. 5.2. Considerations for the "ietf-tls-common" YANG Module This section follows the template defined in Section 3.7.1 of [RFC8407]. The "ietf-tls-common" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. Both of these protocols have mandatory-to-implement secure transport layers (e.g., SSH, TLS) with mutual authentication. Watsen Expires 17 September 2024 [Page 57] Internet-Draft Groupings for TLS Clients and Servers March 2024 The Network Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular users to a pre-configured subset of all available protocol operations and content. Please be aware that this YANG module uses groupings from other YANG modules that define nodes that may be considered sensitive or vulnerable in network environments. Please review the Security Considerations for dependent YANG modules for information as to which nodes may be considered sensitive or vulnerable in network environments. None of the readable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-all" extension has not been set for any data nodes defined in this module. None of the writable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-write" extension has not been set for any data nodes defined in this module. This module defines the RPC "generate-asymmetric-key-pair" that may, if the "ct:cleartext-private-keys" feature is enabled, and the client requests it, return the private clear in cleartext form. It is NOT RECOMMENDED for private keys to pass the server's security perimeter. This module does not define any actions or notifications, and thus the security consideration for such is not provided here. 5.3. Considerations for the "ietf-tls-client" YANG Module This section follows the template defined in Section 3.7.1 of [RFC8407]. The "ietf-tls-client" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040].

Please review the Security Considerations for dependent YANG modules for information as to which nodes may be considered sensitive or vulnerable in network environments. None of the readable data nodes defined in this YANG module are considered sensitive or vulnerable in network environments. The NACM "default-deny-all" extension has not been set for any data nodes defined in this module. All the writable data nodes defined by this module may be considered sensitive or vulnerable in some network environments. For instance, any modification to a key or reference to a key may dramatically alter the implemented security policy. For this reason, the NACM extension "default-deny-write" has been set for all data nodes defined in this module. This module does not define any RPCs, actions, or notifications, and thus the security consideration for such is not provided here. 5.4. Considerations for the "ietf-tls-server" YANG Module This section follows the template defined in Section 3.7.1 of [RFC8407]. The "ietf-tls-server" YANG module defines "grouping" statements that are designed to be accessed via YANG based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040].

All the writable data nodes defined by this module may be considered sensitive or vulnerable in some network environments. For instance, any modification to a key or reference to a key may dramatically alter the implemented security policy.

The "IETF XML" Registry This document registers four URIs in the "ns" subregistry of the IETF XML Registry [RFC3688]. Following the format in [RFC3688], the following registrations are requested: URI: urn:ietf:params:xml:ns:yang:iana-tls-cipher-suite-algs Registrant Contact: The IESG XML: N/A, the requested URI is an XML namespace. URI: urn:ietf:params:xml:ns:yang:ietf-tls-common Registrant Contact: The IESG XML: N/A, the requested URI is an XML namespace.

URI: urn:ietf:params:xml:ns:yang:ietf-tls-server Registrant Contact: The IESG XML: N/A, the requested URI is an XML namespace. 6.2. The "YANG Module Names" Registry This document registers four YANG modules in the YANG Module Names registry [RFC6020]. Following the format in [RFC6020], the following registrations are requested: Watsen Expires 17 September 2024 [Page 60] Internet-Draft Groupings for TLS Clients and Servers March 2024 name: iana-tls-cipher-suite-algs namespace: urn:ietf:params:xml:ns:yang:iana-tls-cipher-suite-algs prefix: tlscsa reference: RFC FFFF name: ietf-tls-common namespace: urn:ietf:params:xml:ns:yang:ietf-tls-common prefix: tlscmn reference: RFC FFFF name: ietf-tls-client namespace: urn:ietf:params:xml:ns:yang:ietf-tls-client prefix: tlsc reference: RFC FFFF name: ietf-tls-server namespace: urn:ietf:params:xml:ns:yang:ietf-tls-server prefix: tlss reference: RFC FFFF 6.3. Considerations for the "iana-tls-cipher-suite-algs" Module This section follows the template defined in Section 4.30.3.1 of [I-D.ietf-netmod-rfc8407bis]. This document presents a script (see Appendix A) for IANA to use to generate the IANA-maintained "iana-tls-cipher-suite-algs" YANG module. The most recent version of the YANG module is available from the "YANG Parameters" registry [IANA-YANG-PARAMETERS]. IANA is requested to add the following note to the registry: | New values must not be directly added to the "iana-tls-cipher- | suite-algs" YANG module. They must instead be added to the "TLS | Cipher Suites" sub-registry of the "Transport Layer Security (TLS) | Parameters" registry [IANA-CIPHER-ALGS]. When a value is added to the "TLS Cipher Suites" sub-registry, a new "enum" statement must be added to the "iana-tls-cipher-suite-algs" YANG module. The "enum" statement, and sub-statements thereof, should be defined as follows: enum Replicates a name from the registry. value Contains the decimal value of the IANA-assigned value. Watsen Expires 17 September 2024 [Page 61] Internet-Draft Groupings for TLS Clients and Servers March 2024 status Include only if a registration has been deprecated or obsoleted. An IANA "Recommended" maps to YANG status "deprecated". Since the registry is unable to express a logical "MUST NOT" recommendation, there is no mapping to YANG status "obsolete", which is unfortunate given Moving single-DES and IDEA TLS ciphersuites to Historic (https://datatracker.ietf.org/doc/status-change-tls-des- idea-ciphers-to-historic) . description Contains "Enumeration for the 'TLS_FOO' algorithm.", where "TLS_FOO" is a placeholder for the algorithm's name (e.g., "TLS_PSK_WITH_AES_256_CBC_SHA"). reference Replicates the reference(s) from the registry with the title of the document(s) added. Unassigned or reserved values are not present in the module. When the "iana-tls-cipher-suite-algs" YANG module is updated, a new "revision" statement with a unique revision date must be added in front of the existing revision statements. The "revision" must have a "description" statement explaining why the the update occurred, and must have a "reference" substatement that points to the document defining the registry update that resulted in this change. For instance: revision 2024-02-02 { description "This update reflect the update made to the underlying Foo Bar registry per RFC XXXX."; reference "RFC XXXX: Extend the Foo Bars Registry to Support Something Important"; } IANA is requested to add the following note to the "TLS Cipher Suites" sub-registry of the "Transport Layer Security (TLS) Parameters" registry [IANA-CIPHER-ALGS]. | When this registry is modified, the YANG module "iana-tls-cipher- | suite-algs" [IANA-YANG-PARAMETERS] must be updated as defined in | RFC FFFF.

Change Log B.1. 00 to 01 * Noted that '0.0.0.0' and '::' might have special meanings. * Renamed "keychain" to "keystore". B.2. 01 to 02 * Removed the groupings containing transport-level configuration. Now modules contain only the transport-independent groupings. * Filled in previously incomplete 'ietf-tls-client' module. * Added cipher suites for various algorithms into new 'ietf-tls- common' module. B.3. 02 to 03 * Added a 'must' statement to container 'server-auth' asserting that at least one of the various auth mechanisms must be specified. * Fixed description statement for leaf 'trusted-ca-certs'. B.4. 03 to 04 * Updated title to "YANG Groupings for TLS Clients and TLS Servers" * Updated leafref paths to point to new keystore path Watsen Expires 17 September 2024 [Page 149] Internet-Draft Groupings for TLS Clients and Servers March 2024 * Changed the YANG prefix for ietf-tls-common from 'tlscom' to 'tlscmn'. * Added TLS protocol verions 1.0 and 1.1. * Made author lists consistent * Now tree diagrams reference ietf-netmod-yang-tree-diagrams * Updated YANG to use typedefs around leafrefs to common keystore paths * Now inlines key and certificates (no longer a leafref to keystore) B.5. 04 to 05 * Merged changes from co-author. B.6. 05 to 06 * Updated to use trust anchors from trust-anchors draft (was keystore draft) * Now Uses new keystore grouping enabling asymmetric key to be either locally defined or a reference to the keystore. B.7. 06 to 07 * factored the tls-[client|server]-groupings into more reusable groupings. * added if-feature statements for the new "x509-certificates" feature defined in draft-ietf-netconf-trust-anchors. B.8. 07 to 08 * Added a number of compatibility matrices to Section 5 (thanks Frank!) * Clarified that any configured "cipher-suite" values need to be compatible with the configured private key. B.9. 08 to 09 * Updated examples to reflect update to groupings defined in the keystore draft. * Add TLS keepalives features and groupings. Watsen Expires 17 September 2024 [Page 150] Internet-Draft Groupings for TLS Clients and Servers March 2024 * Prefixed top-level TLS grouping nodes with 'tls-' and support mashups. * Updated copyright date, boilerplate template, affiliation, and folding algorithm. B.10. 09 to 10 * Reformatted the YANG modules. B.11. 10 to 11 * Collapsed all the inner groupings into the top-level grouping. * Added a top-level "demux container" inside the top-level grouping. * Added NACM statements and updated the Security Considerations section. * Added "presence" statements on the "keepalive" containers, as was needed to address a validation error that appeared after adding the "must" statements into the NETCONF/RESTCONF client/server modules. * Updated the boilerplate text in module-level "description" statement to match copyeditor convention. B.12. 11 to 12 * In server model, made 'client-authentication' a 'presence' node indicating that the server supports client authentication. * In the server model, added a 'required-or-optional' choice to 'client-authentication' to better support protocols such as RESTCONF. * In the server model, added a 'inline-or-external' choice to 'client-authentication' to better support consuming data models that prefer to keep client auth with client definitions than in a model principally concerned with the "transport". * In both models, removed the "demux containers", floating the nacm:default-deny-write to each descendant node, and adding a note to model designers regarding the potential need to add their own demux containers. * Fixed a couple references (section 2 --> section 3) Watsen Expires 17 September 2024 [Page 151] Internet-Draft Groupings for TLS Clients and Servers March 2024 B.13. 12 to 13 * Updated to reflect changes in trust-anchors drafts (e.g., s/trust- anchors/truststore/g + s/pinned.//) B.14. 12 to 13 * Removed 'container' under 'client-identity' to match server model. * Updated examples to reflect change grouping in keystore module. B.15. 13 to 14 * Removed the "certificate" container from "client-identity" in the ietf-tls-client module. * Updated examples to reflect ietf-crypto-types change (e.g., identities --> enumerations) B.16. 14 to 15 * Updated "server-authentication" and "client-authentication" nodes from being a leaf of type "ts:certificates-ref" to a container that uses "ts:inline-or-truststore-certs-grouping". B.17. 15 to 16 * Removed unnecessary if-feature statements in the -client and -server modules. * Cleaned up some description statements in the -client and -server modules. * Fixed a canonical ordering issue in ietf-tls-common detected by new pyang. B.18. 16 to 17 * Removed choice inline-or-external by removing the 'external' case and flattening the 'local' case and adding a "client-auth- supported" feature. * Removed choice required-or-optional. * Updated examples to include the "*-key-format" nodes. Watsen Expires 17 September 2024 [Page 152] Internet-Draft Groupings for TLS Clients and Servers March 2024 * Augmented-in "must" expressions ensuring that locally-defined public-key-format are "ct:tls-public-key-format" (must expr for ref'ed keys are TBD). B.19. 17 to 18 * Removed the unused "external-client-auth-supported" feature. * Made client-indentity optional, as there may be over-the-top auth instead. * Added augment to uses of inline-or-keystore-symmetric-key-grouping for a psk "id" node. * Added missing presence container "psks" to ietf-tls-server's "client-authentication" container. * Updated examples to reflect new "bag" addition to truststore. * Removed feature-limited caseless 'case' statements to improve tree diagram rendering. * Refined truststore/keystore groupings to ensure the key formats "must" be particular values. * Switched to using truststore's new "public-key" bag (instead of separate "ssh-public-key" and "raw-public-key" bags). * Updated client/server examples to cover ALL cases (local/ref x cert/raw-key/psk). B.20. 18 to 19 * Updated the "keepalives" containers in part to address Michal Vasko's request to align with RFC 8071, and in part to better align to RFC 6520. * Removed algorithm-mapping tables from the "TLS Common Model" section * Removed the 'algorithm' node from the examples. * Renamed both "client-certs" and "server-certs" to "ee-certs" * Added a "Note to Reviewers" note to first page. B.21. 19 to 20 Watsen Expires 17 September 2024 [Page 153] Internet-Draft Groupings for TLS Clients and Servers March 2024 * Modified the 'must' expression in the "ietf-tls-client:server- authention" node to cover the "raw-public-keys" and "psks" nodes also. * Added a "must 'ca-certs or ee-certs or raw-public-keys or psks'" statement to the ietf-tls-server:client-authentication" node. * Added "mandatory true" to "choice auth-type" and a "presence" statement to its ancestor. * Expanded "Data Model Overview section(s) [remove "wall" of tree diagrams]. * Moved the "ietf-tls-common" module section to proceed the other two module sections. * Updated the Security Considerations section. B.22. 20 to 21 * Updated examples to reflect new "cleartext-" prefix in the crypto- types draft. B.23. 21 to 22 * In both the "client-authentication" and "server-authentication" subtrees, replaced the "psks" node from being a P-container to a leaf of type "empty". * Cleaned up examples (e.g., removed FIXMEs) * Fixed issues found by the SecDir review of the "keystore" draft. * Updated the "psk" sections in the "ietf-tls-client" and "ietf-tls- server" modules to more correctly reflect RFC 4279. B.24. 22 to 23 * Addressed comments raised by YANG Doctor in the ct/ts/ks drafts. B.25. 23 to 24 * Added missing reference to "FIPS PUB 180-4". * Added identity "tls-1.3" and updated description statement in other identities indicating that the protocol version is obsolete and enabling the feature is NOT RECOMMENDED. Watsen Expires 17 September 2024 [Page 154] Internet-Draft Groupings for TLS Clients and Servers March 2024 * Added XML-comment above examples explaining the reason for the unexpected top-most element's presence. * Added missing "client-ident-raw-public-key" and "client-ident-psk" featutes. * Aligned modules with `pyang -f` formatting. * Fixed nits found by YANG Doctor reviews. * Added a 'Contributors' section.
