Field --> Field Maintenance Equipment:
field equipment status

Definitions

field equipment status (Information Flow): Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

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

Field Maintenance Equipment (Destination 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.

Communication Solutions

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) - Guaranteed Secure Internet (ITS)

Solution Description

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with (None-Data) with those for I-I: Guaranteed Secure Internet (ITS). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-I: Guaranteed Secure Internet (ITS) standards include lower-layer standards that support secure communications with guaranteed delivery between ITS equipment using X.509 or IEEE 1609.2 security certificates.

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.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Low Moderate High
Basis The operational state of field devices, if known to an attacker or individual with criminal intent, could be used to facilitate the commission of a crime. Individual devices may be more or less important in this context; for example knowing whether a security camera is operating is probably more relevant to the criminal than knowing if the DMS is operating, though the latter could still be useful info. Instances of this flow that are local minimize this risk however, so for these local flows Confidentiality is considered LOW. If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. This must be timely to support operational uptime requirements. Lack of monitoring will lead to less uptime, which will impact security, mobility and in some cases, safety.
