US: NTCIP Message Sign - SNMPv3/TLS

Description

This solution is used within the U.S.. It combines standards associated with US: NTCIP Message Sign with those for I–F: SNMPv3/TLS. The US: NTCIP Message Sign standards include upper–layer standards required to implement center–to–field message sign 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.

Includes Standards

Level	DocNum	FullName	Description
Mgmt	NTCIP 1201	NTCIP Global Object (GO) Definitions	This standard defines SNMP objects (data elements) used by a wide range of field devices like time and versioning information.
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 1203	NTCIP Object Definitions for Dynamic Message Signs (DMS)	This standard defines SNMP objects (data elements) for monitoring and controlling dynamic message signs (such as variable message signs).
Facilities	NTCIP 1203	NTCIP Object Definitions for Dynamic Message Signs (DMS)	This standard defines SNMP objects (data elements) for monitoring and controlling dynamic message signs (such as variable message signs).

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.
