US: NTCIP CCTV - SNMPv3/TLS

Description:

This solution is used within the U.S.. It combines standards associated with US: NTCIP CCTV with those for I-F: SNMPv3/TLS. The US: NTCIP CCTV standards include upper-layer standards required to implement center-to-field CCTV communications (data only). 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

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True	Medium	Out of date (medium)	Standardization Gap	The standard includes normative references to other standards that have been subject to significant changes that can impact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.
