Maint and Constr Field Personnel --> Field Maintenance Equipment:
field personnel equipment input

Definitions

field personnel equipment input (Information Flow): User input from field personnel that supports querying, controlling, and configuring field equipment.

Maint and Constr Field Personnel (Source Physical Object): Represents the people that perform maintenance and construction field activities including vehicle and equipment operators, field supervisory personnel, field crews, and work zone safety personnel. Information flowing from the Maintenance and Construction Field Personnel will include those system inputs specific to maintenance and construction operations, such as information regarding work zone status, or the status of maintenance actions. The field personnel are also monitored within the work zone to enhance work zone safety. Information provided to Maintenance and Construction Field Personnel includes dispatch requests, maintenance and construction actions to be performed, and work zone safety warnings.

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.

Interoperability Description
Not Applicable Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Moderate High High
Basis Field subsystem controls should not be casually viewable as they their observation could serve as ad-hoc training for would-be attackers, not to mention that this interface is likely to include an authentication/authorization mechanism such as a password that if compromised, could compromise the device. System maintenance flows are the primary interface between field personnel and field equipment, and must present accurate data or inappropriate maintenance actions may be taken.
