Definitions

field equipment configuration settings (Information Flow): Control settings and parameters that are used to configure field equipment.

Field Maintenance Equipment (Source Physical Object): 'Field Maintenance Equipment' represents the portable equipment used by field personnel to locally troubleshoot, initialize, reprogram, and test infrastructure equipment. It may include a laptop, specialized diagnostics tools, or any other general purpose or specialized equipment that is interfaced locally to infrastructure equipment to support maintenance and repair.

Field (Destination Physical Object): This general physical object is used to model core capabilities that are common to any piece of field equipment.

(None-Data) - Secure Internet (ITS) (32)
US: NTCIP Generic Device - SNMPv1 (32)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - Secure Internet (ITS)

Solution Description

This solution is used within Australia, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. 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.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability	Description
Local	In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides.

Basis	Configuration settings could be sensitive; if an attacker knows precisely how a device is configured, it may facilitate an attack.	Commands to ITS Roadway Equipment must be authenticated as having come from a source entitled to issue that command, or roadway equipment may be comprimised. Similarly, commands and configuration must be guaranteed to be correct; not manipulated midstream or corrupted, or the roadway equipment may be mis-configured or compromised.	The ability to remotely diagnose and configure devices is inherent to their successful operation. If this link is down it either suggests or will prompt field maintenance activity, which has a non-trivial cost and resource impact.
