US: NTCIP Video Switches - SNMPv3/TLS

Description

This solution is used within the U.S.. It combines standards associated with US: NTCIP Video Switches with those for I–F: SNMPv3/TLS. The US: NTCIP Video Switches standards include upper–layer standards required to implement center–to–field video switch 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 1205	NTCIP Objects for CCTV Camera Control	This standard defines SNMP objects (data elements) for control and monitoring of closed–circuit television (CCTV) camera controllers.
ITS Application Entity	NTCIP 1208	NTCIP Object Definitions for Video Switches	This standard defines SNMP objects (data elements) for the control and monitoring of video switches.
Facilities	NTCIP 1205	NTCIP Objects for CCTV Camera Control	This standard defines SNMP objects (data elements) for control and monitoring of closed–circuit television (CCTV) camera controllers.
Facilities	NTCIP 1208	NTCIP Object Definitions for Video Switches	This standard defines SNMP objects (data elements) for the control and monitoring of video switches.

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.

Issues

Issue	Severity	Description	Associated Standard	Associated Triple
Out of date (medium)	Medium	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.	IETF RFC 6353 TLS for SNMP	(All)
Update data to SNMPv3	Low	Data has been defined for SNMPv1, but needs to be updated to SNMPv3 format.	(None)	(All)
Use TLS for SNMP Option	Low	The standard allows for multiple security mechanisms. The only defined mechanism that meets the requirements for C–ITS is the one based on TLS.	(None)	(All)
