US: NTCIP Transportation Sensors - SNMPv1/TLS
Description:
This solution is used within the U.S.. It combines standards associated with US: NTCIP Transportation Sensors with those for I-F: SNMPv1/TLS. The US: NTCIP Transportation Sensors standards include upper-layer standards required to implement center-to-field transportation sensors (e.g., vehicle detectors) communications (e.g., real-time). The I-F: SNMPv1/TLS standards include lower-layer standards that define one way to retrofit basic security into SNMPv1 implementations (mainly in the US); however, this only secures the communications link and does not provide end-application security and is not recommended for new deployments.

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.

Security
|
IETF RFC 8446
|
IETF RFC 8446 TLS
|
This standard (RFC) specifies Version 1.3 of the Transport Layer Security (TLS) protocol. The TLS protocol provides communications security over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.

TransNet

IETF RFC 793
|
IETF RFC 793 TCP
|
This standard (RFC) defines the main connection-oriented Transport Layer protocol used on Internet-based networks.

IP Alternatives
|
A set of alternative standards that allows for the selection of IPv4 or IPv6.

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.
