SU13: Personnel Device Maintenance

This service package supports maintenance of ITS personnel devices. Like other device maintenance service packages, this SP is drawn at a high level of abstraction to cover the basic interfaces and functionality associated with maintaining personnel devices. The focus here is on devices that are used by transportation professionals. The maintenance of smart phones, tablets, laptops, and other general purpose devices that are used by travelers is coordinated between the travelers and the providers of the devices and communications services, which is beyond the scope of the architecture.

Physical Object Class Description
Center Center This general physical object is used to model core capabilities that are common to any center.
Center Personnel Center 'Center Personnel' represent system operators and other personnel that work within a transportation center. This interface supports modeling of general human interactions that are common to any center.
Maint and Constr Field Personnel Field 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.
Personnel Device Personal 'Personnel Device' represents devices used by emergency personnel or maintenance and construction personnel in the field. In the case of emergency personnel, the devices would include body cameras or smartphones (and their peripherals) that can be used by emergency personnel to provide images or video as well as send or receive data regarding the incident. The devices could also be used for incident scene safety messages to the personnel. In the case of maintenance and construction field personnel, the devices could be cellular phones or specialized safety devices that would be used for work zone safety messages to the personnel.
Service Monitor System Support The 'Service Monitor System' represents one or more center-based systems that provide monitoring, management and control services necessary to other applications and/or devices operating within the Connected Vehicle Environment. These support services enable other applications to provide transportation services.

Includes Functional Objects:

Functional Object Description Physical Object
Center Personal Information Device Management 'Center Personal Information Device Management' is the back office application that supports monitoring and maintenance of Personal Information Devices. Most Personal Information Device management is the province of device manufacturers, service providers, and their clients, which is beyond the scope of an ITS architecture. For roadside safety applications, particularly those that are operated by field personnel working on or close to the right of way, the operating center may manage the devices and the hosted safety applications. For these devices and applications, this functional object monitors the performance and configuration of the devices and installed applications, and the communications links. Center

Source Destination Information Flow Confidentiality Integrity Availability
Basis Basis Basis
Center Center Personnel center operator data High High High
Direct interactions between personnel and systems in a backoffice environment are effectively protected by physical means, so long as the interaction is in a dedicated facility. If this interaction is virtual (i.e. ,the center is not directly in front of the Center Personnel, like in a cloud-based system) then the user's input requires some degree of obfuscation depending on sensitivity of information. Given that this could include information about compromised or ineffectual systems, including security systems, the potential for damage is high. Thus, HIGH. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.
Center Personnel Device personnel device commands Moderate Moderate Moderate
Commands could be sensitive and should include authentication data, thus should be MODERATE. Commands to PIDs 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 PID 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.

If this link is down it either suggests or will prompt field maintenance activity, which has a non-trivial cost and resource impact.
Center Personnel Device personnel device software install/upgrade High High Moderate
PID control, configuration and software/firmware update should all be protected from view. A hostile third party could use this information to reverse engineer control/configuration/update processes, and use that information in an attack across a broad swatch of similar devices, which would have severe effects to the installed base. PID control, configuration and update need to be correct or the PID may be misconfigured, which for some applications could have severe safety impacts. PID control, configuration and update needs to be available; however the availability requirement is probably less than Integrity, as without this flow the PID can continue to operate. The exception would be post-cyber attack, when this flow becomes critical.

Maint and Constr Field Personnel Personnel Device personnel input Low Moderate Low
Input related to Emergency-related application. There could be sensitive information depending on the application, particularly regarding the health of someone involved in an incident the emergency personnel is responding to, in which case this rating might increase. This data should be correct to enable accurate application functionality, but is likely not critical and easily corrected. There should generally other ways to accomplish this flow.
Personnel Device Center personnel device status Moderate Moderate Low
Will include some sort of identifier for the PID, which could be used in combination with the status and configuration data as a means of identifying the type of PID, or in areas of low penetration the actual PID and the user. Since this is used to monitor the health of the PID, any corruption or modification of this information could lead to unnecessary maintenance activity, or delay necessary such activity. Impact will be limited to the PIDs who's flows were so affected. Unlikely that this needs to be reported often.
Personnel Device Maint and Constr Field Personnel personnel updates Low High Moderate
This data is informing the user of safety-related issues in the local transportation environment. It probably does not contain anything sensitive, and should not matter if another person can observe it. This is the information that is presented to the individual in a work zone or incident response area that may be unpredictable in its formation. If the user receives incorrect information, they may act in an unsafe manner. If this information is not made available to the pedestrian, then the user may be endangered. This is the not only mechanism the user may have to avoid potential dangers (they can observe directly).
Personnel Device Service Monitor System personnel device status Moderate Moderate Low
Will include some sort of identifier for the PID, which could be used in combination with the status and configuration data as a means of identifying the type of PID, or in areas of low penetration the actual PID and the user. Since this is used to monitor the health of the PID, any corruption or modification of this information could lead to unnecessary maintenance activity, or delay necessary such activity. Impact will be limited to the PIDs who's flows were so affected. Unlikely that this needs to be reported often.
Service Monitor System Center personnel device fault data Moderate Moderate Moderate
Device status information should not be viewable by third parties, as those with criminal intent may use this information toward their own ends. If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. Scope is small, but impact significant if this occurs with many instances. A delay in reporting this may cause a delay in necessary maintenance. Considered higher availability requirement than the source flow (RSE status) because this information aggregates many instances of the source.
