US: NTCIP Environmental Sensors - SNMPv3/TLS
Description
This solution is used within the U.S.. It combines standards associated with US: NTCIP Environmental Sensors with those for I–F: SNMPv3/TLS. The US: NTCIP Environmental Sensors standards include upper–layer standards required to implement center–to–field weather and environmental sensor communications. The I–F: SNMPv3/TLS standards include lower–layer standards that support secure center–to–field and field–to–field communications using simple network management protocol (SNMPv3); implementations are strongly encouraged to use the TLS for SNMP security option for this solution to ensure adequate security.

| Security | IETF RFC 6353 | Transport Layer Security (TLS) Transport Model for the Simple Network Management Protocol (SNMP) | This standard (RFC) defines how to use the TLS authentication service to provide authentication within the access control mechanism of SNMP. |
| ITS Application Entity | NTCIP 1204 | NTCIP Environmental Sensor Station Interface Standard | This standard defines SNMP objects (data elements) for monitoring and controlling environmental sensor stations (especially road weather stations). |
| Facilities | NTCIP 1204 | NTCIP Environmental Sensor Station Interface Standard | This standard defines SNMP objects (data elements) for monitoring and controlling environmental sensor stations (especially road weather stations). |

| TransNet | IETF RFC 4291 | IP Version 6 Addressing Architecture | This standard (RFC) defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses. |
| TransNet | IETF RFC 4443 | Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification | This standard (RFC) defines the control messages to manage IPv6. |
| TransNet | IETF RFC 8200 | Internet Protocol, Version 6 | This document specifies version 6 of the Internet Protocol (IPv6). |
| TransNet | IETF RFC 9293 | Transmission Control Protocol | This document specifies the Transmission Control Protocol (TCP). TCP is an important transport–layer protocol in the Internet protocol stack, and it has continuously evolved over decades of use and growth of the Internet. Over this time, a number of changes have been made to TCP as it was specified in RFC 793, though these have only been documented in a piecemeal fashion. This document collects and brings those changes together with the protocol specification from RFC 793. This document obsoletes RFC 793, as well as RFCs 879, 2873, 6093, 6429, 6528, and 6691 that updated parts of RFC 793. It updates RFCs 1011 and 1122, and it should be considered as a replacement for the portions of those documents dealing with TCP requirements. It also updates RFC 5961 by adding a small clarification in reset handling while in the SYN–RECEIVED state. The TCP header control bits from RFC 793 have also been updated based on RFC 3168. |
| Access | NTCIP 2104 | NTCIP SP–Ethernet | This standard defines the Access Layer for center–to–field communications where the local connection is some variant of Ethernet. |
Readiness: High–Moderate
Readiness Description
One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
