US: NTCIP Message Sign - SNMPv1

Description:

This solution is used within the U.S.. It combines standards associated with US: NTCIP Message Sign with those for I-F: SNMPv1. The US: NTCIP Message Sign standards include upper-layer standards required to implement center-to-field message sign communications. The I-F: SNMPv1 standards include lower-layer standards that define how SNMPv1, which does not provide any security, is used within some deployments within the ITS industry. This solution is no longer recommended due to known security vulnerabilities.

Comm Profile: I-F: SNMPv1

Level	Doc #	Standard	Description
Access		Field SubNet Alternatives	A set of alternative standards that defines various SubNet Layer alternatives for use in center-to-field and field-to-field connections.
Facilities	NTCIP 2301	Bundle: NTCIP AP-STMF	This standard specifies the standards required for the Facilities Layer for most center-to-field communications using the SNMPv1 GET-SET paradigm.
Mgmt		Bundle: SNMPv1 MIB	A bundle of standards (RFCs) used to manage an Internet device that supports SNMPv1. SNMPv1 is deprecated as it does not provide any security, which exposes the entire C-ITS environment to well-known vulnerabilities.
TransNet		Field TransNet Alternatives	A set of alternative standards that defines various TransNet Layer alternatives that are typical for center-to-field and field-to-field communications. TP-Internet can be used with virtually any SubNet; TP-Transportation is restricted to single-hop networks and is typically only used over PMPP.

Data Profile: US: NTCIP Message Sign

Level	Doc #	Standard	Description
Facilities	NTCIP 1203	NTCIP Message Sign Objects	This standard defines SNMP objects (data elements) for monitoring and controlling dynamic message signs (such as variable message signs).
ITS Application Entity	NTCIP 1203	NTCIP Message Sign Objects	This standard defines SNMP objects (data elements) for monitoring and controlling dynamic message signs (such as variable message signs).
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:

Many serious issues. This category includes solutions that have not been standardized, or do not have a basic level of interoperability or security. Consider selecting a different communications solution or if this is not possible (eg. a pilot of a new application that has not been standardized), take additional measures to provide an acceptable level of security or interoperability.
