US: NTCIP Signal System Masters - SNMPv1/TLS
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: NTCIP Signal System Masters with those for I-F: SNMPv1/TLS. The US: NTCIP Signal System Masters standards include upper-layer standards required to implement center-to-field signal-system master communications. 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.Relevant Regions:
- Canada
- United States
Comm Profile: I-F: SNMPv1/TLS
Comm Class: MAN - Metropolitan Area Network

Solution Issues Severity: 6
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| True | Medium | Security inadequate | Security Gap | The solution does not provide adequate communications security for the information triple, which potentially jeopardizes C-ITS operations. |
| True | Medium | Unvetted by community | Standardization Gap | The proposed solution uses a suite of standards that is accepted within some communities, but has not necessarily been accepted for use within the context of this information triple. |
