US: NTCIP Signal Priority - SNMPv3/TLS

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: NTCIP Signal Priority with those for I-F: SNMPv3/TLS. The US: NTCIP Signal Priority standards include upper-layer standards required to implement center-to-field traffic signal control priority communications (e.g., for busses and emergency vehicles). 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.

Solution Issues Severity: 5

The severity issue score calculation only includes issues associated with standards that are included by default.

Solution Issues:

Default Severity Name Type Description
True Low Update data to SNMPv3 Standardization Gap Data has been defined for SNMPv1, but needs to be updated to SNMPv3 format.
True Low Use TLS for SNMP Option Security Gap The standard allows for multiple security mechanisms. The only defined mechanism that meets the requirements for C-ITS is the one based on TLS.
True Medium Out of date (medium) Standardization Gap The standard includes normative references to other standards that have been subject to significant changes that can impact interoperability or security of systems and the industry has not specified if and how these updates should be implemented for deployments of this standard.
