METR: Distribution Requirements - Secure Wireless Internet (ITS)

Description:

This solution is used within Canada and the U.S.. It combines standards associated with METR: Distribution Requirements with those for I-M: Secure Wireless Internet (ITS). The METR: Distribution Requirements standards include upper-layer standards required to distribute traffic regulations from a distribution center. The I-M: Secure Wireless Internet (ITS) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Solution Issues Severity: 27

Solution Issues:

Default	Severity	Name	Type	Description
False	Low	Overlap of standards (Minor)	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow. However, as this information transfer is infrastructure-based, agencies can deploy a solution throughout their jurisdiction with minimal downside and can use gateways to connect to other technologies.
False	Low	Time synchronization	Performance / Applicability Gap	The standard requires a highly accurate time shared between participants.
False	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
False	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
False	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.
False	High	Regulatory Issue	Standardization Gap	Deployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term.
True	Medium	Outdated security reference	Security Gap	The standard solution includes an outdated security reference.
True	High	Draft not available (Critical)	Standardization Gap	The standards development organization has established a work item for the subject standard but a draft is not available for this critical feature to enable the interface. The draft may be missing due to the work item being new or simply a lack of activity on the work item.
