TUF - Secure Internet (ITS)

Description:

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with TUF with those for I-I: Secure Internet (ITS). The TUF standards include upper-layer standards required to install and update application software. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Solution Issues Severity: 15

Solution Issues:

Default	Severity	Name	Type	Description
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.
True	Low	Not a standard (minor)	Standardization Gap	The document is publicly available and widely used but it is not currently a formal standard.
True	Medium	Outdated security reference	Security Gap	The standard solution includes an outdated security reference.
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.
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.
