EU: Signal Control Messages - Secure Internet (ITS)

Description:

This solution is used within Australia and the E.U.. It combines standards associated with EU: Signal Control Messages with those for I-I: Secure Internet (ITS). The EU: Signal Control Messages standards include upper-layer standards required to implement signal control information flows. 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: 13

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 Data not defined in standard format ITS Info Gap The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.
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 Secure data access not provided Security Gap The solution does not define rules on how the application entity authenticates requests to accept or provide data.
True High Data/comm profile pairing Standardization Gap There are ambiguities as to how to (or if one should) couple the upper-layer standards defined in this solution with the indicated lower-layer standards.
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.
