US: NTCIP Environmental Sensors - Wireless SNMPv3/TLS

Description:

This solution is used within the U.S.. It combines standards associated with US: NTCIP Environmental Sensors with those for I-M: Wireless 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-M: Wireless SNMPv3/TLS standards include lower-layer standards that support secure infrastructure-to-mobile communications using simple network management protocol (SNMPv3).

Comm Profile: I-M: Wireless SNMPv3/TLS

Level	Doc #	Standard	Description
Access		Wireless Internet Alternatives (NA)	A set of alternative standards that supports any technology that allows a mobile device (e.g., a vehicle) to connect to the Internet (or an intranet) while stationary or moving within a limited area. For example, this would include both Wi-Fi and cellular technologies among others. NOTE: Use of the WAVE Subnet should be coupled with use of IEEE 1609.3 at the TransNet Layer.
Facilities	ISO 15784-2	Bundle: ISO 15784-2	ISO 15784-2 specifies the standards that provide a mechanism to exchange data and messages in the following cases: a) between a traffic management center(s) and roadside modules for traffic management; and b) between roadside modules used for traffic management.
Mgmt		Bundle: SNMPv3 MIB	A bundle of standards (RFCs) that groups the common management information bases (MIBs) used to manage IP networks at the transport layer and below using SNMPv3.
Security	IETF RFC 6353	IETF RFC 6353 TLS for SNMP	This standard (RFC) defines how to use the TLS authentication service to provide authentication within the access control mechanism of SNMP.
TransNet		Internet Transport Alternatives	A set of alternative standards that identifies the two major options for the transport layer for mainstream IP-based deployments.
TransNet		IP Alternatives	A set of alternative standards that allows for the selection of IPv4 or IPv6.

Data Profile: US: NTCIP Environmental Sensors

Level	Doc #	Standard	Description
Facilities	NTCIP 1204	NTCIP Weather Station Objects	This standard defines SNMP objects (data elements) for monitoring and controlling environmental sensor stations (especially road weather stations).
ITS Application Entity	NTCIP 1204	NTCIP Weather Station Objects	This standard defines SNMP objects (data elements) for monitoring and controlling environmental sensor stations (especially road weather stations).
Mgmt	NTCIP 1201	NTCIP Global Objects	This standard defines SNMP objects (data elements) used by a wide range of field devices like time and versioning information.

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.
