Expires 2 March 2023 [Page 2] Internet-Draft LISP-YANG August 2022 1. Introduction The Locator/ID Separation Protocol (LISP) defines several network elements subject to be configured. This document presents the YANG data models required for basic configuration of all major LISP [RFC6830] elements. The models also capture some essential operational data elements as well. 1.1. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD 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. 1.2. Tree Diagrams This document uses the graphical representation of data models defined in [RFC8340]. 1.3. Prefixes The table below provides a summary of the prefixes used by this document.

Security Considerations The YANG modules specified in this document define a schema for data that is designed to be accessed via network management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS Ermagan, et al. Expires 2 March 2023 [Page 76] Internet-Draft LISP-YANG August 2022 [RFC8446]. The NETCONF access control model [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a pre- configured subset of all available NETCONF or RESTCONF protocol operations and content. The security considerations of LISP control-plane [RFC6833] and LISP data-plane [RFC6830] as well as the LISP threat analysis [RFC7835] apply to this YANG model. There are a number of data nodes defined in this YANG module that are writable/creatable/deletable (i.e., config true, which is the default). These data nodes may be considered sensitive or vulnerable in some network environments. Write operations (e.g., edit-config) to these data nodes without proper protection can have a negative effect on network operations. These are the subtrees and data nodes and their sensitivity/vulnerability: /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol/ lisp:lisp/ Access to the locator-sets node may modify which interfaces are used for data and/or control traffic as well as affect the load balancing of data-plane traffic. Access to the lisp-role node may prevent the device from perform its intended data-plane and/or control-plane operation. Access to the router-id node allows to modify the unique identifier of the device, which may result in disruption of its LISP control-plane operation. Access to the vpn node may allow to redirect data-plane traffic to erroneous local or remote network instances. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:map-server Access to the sites node can prevent authorized devices from registering mappings in the Map-Server and/or allow unauthorized devices to so. Access to the vpn node can result in corrupted mapping sate that may propagate across the LISP network, potentially resulting in forwarding of data-plane traffic to arbitrary destinations and general disruption of the data-plane operation. Access to mapping-system-type and/or ddt-mapping-system nodes may prevent the device to connect to the Mapping System infrastructure and consequentially to attract Map-Request messages. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:map-resolver Ermagan, et al. Expires 2 March 2023 [Page 77] Internet-Draft LISP-YANG August 2022 Access to mapping-system-type, ms-address and/or ddt-mapping-system nodes may prevent the device to connect to the Mapping System infrastructure and forward Map-Request messages. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:itr Access to the rloc-probing node can increase the control-plane overhead in the device or affect the capability of the device to detect failures on the underlay. Access to the itr-rlocs node may prevent the device from getting Map-Reply messages. Access to the map-resolvers node can prevent the device from sending its Map- Request messages to valid Map-Resolvers. Access to the proxy-etrs nodes can affect the capability of the device to send data-plane traffic towards non-LISP destinations. Access to the map-cache node can result in forwarding of data-plane traffic to arbitrary destinations and general disruption of data-plane operation. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:etr Access to the map-servers node can prevent the device from registering its local mappings into the Mapping System. Access to the local-eids node can disrupt data-plane operation on the device and/or result in the device registering corrupted mappings into the Mapping System. Some of the readable data nodes in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes. These are the subtrees and data nodes and their sensitivity/vulnerability: /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol/ lisp:lisp Access to the locator-sets node can expose the locators the device is using for its control and/or data operation. Access to the lisp-role node can disclose the LISP roles instantiated at the device which facilitates mounting attacks against the device. Access to the router-id node can expose the unique identifier of device which may allow a third party to track its control-plane operation and/or impersonate the device. Access to the vpn node can leak the local mapping between LISP Instance IDs and local network instances. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:map-server Ermagan, et al. Expires 2 March 2023 [Page 78] Internet-Draft LISP-YANG August 2022 Access to the sites node can expose the credentials used to register mappings and allow unauthorized devices to do so. Access to the vpn node can expose the mappings currently registered in the device, which has privacy implications. Access to the mapping-system-type node may reveal the Mapping System in use which can be used to mount attacks against the device and/or the Mapping System. Access to the summary and counters nodes may expose operational statistics of the device. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:map-resolver Access to the mapping-system-type node may reveal the Mapping System in use which can be used to mount attacks against the device and/or the Mapping System. Access to the ms-address and/or ddt-mapping- system nodes can leak the information about the Mapping System infrastructure used by the device, which can be used to block communication and/or mount attacks against it. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:itr Access to the rloc-probing node can expose if and how the device is using control-plane signaling to probe underlay locators. Access to the itr-rlocs node may disclose the addresses the device is using to receive Map-Reply messages. Access to the map-resolvers node can expose the Map-Resolvers used by the device, which can be used to mount attacks against the device and/or the Mapping System. Access to the proxy-etrs node can disclose the PETRs used by the device, which can be used to mount attacks against the device and/or PETRs. Access to the map-cache node can expose the mappings currently cached in the device, which has privacy implications. /rt:routing/rt:control-plane-protocols/rt:control-plane- protocol/lisp:lisp/lisp:etr Access to the map-servers node can expose the credentials used by the device to register mappings into the Mapping System allowing an unauthorized device to impersonate and register mappings on behalf the authorized device. Access to the local-eids node can expose the local EIDs currently being served by the device, which has privacy implications. 11. Normative References Ermagan, et al.
