US: GTFS - Secure Internet (ITS)

Description:

This solution is used within the U.S.. It combines standards associated with US: GTFS with those for I-I: Secure Internet (ITS). The US: GTFS standards include upper-layer standards required to implement public, transit-related communications. 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: 10

The severity issue score calculation only includes issues associated with standards that are included by default.

Solution Issues:

Default Severity Name Type Description
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 High Application specification not defined ITS Info Gap The logic, performance, and application security rules are not defined for this information flow.
False Medium Option not standardized Standardization Gap The option set includes at least one option that is not (yet) defined in a standard.
False Medium Uncertainty about trust revocation mechanism Security Gap The mechanisms used to prevent bad actors from sending authorized messages is unproven.
