While time reference should be universally available, time reference coupled with vehicle location is tracking data. This flow is internal to a vehicle, but should probably be encrypted to discourage hacking and snooping on the vehicle bus. Thus MODERATE. Location and time data is the basis for crash imminent safety and a host of other applications. Corruption of this flow could lead directly to a vehicle accident. If this information is not available, crash imminent safety applications depending on this information will not function properly.

Commands could be sensitive, however this flow is local, meaning the Field Support Equipment is proximate to the ITS Roadway Equipment. Thus the risk of interception should be low. There may also be constraints on this flow that require this information to be transmitted in the clear. 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. Without the ability to locally diagnose, operate, update and configure ITS Roadway Equipment, the equipment is effectively out of control and would have to be taken out of service.

ITS Roadway Equipment Field Maintenance Equipment field equipment status Low Moderate High
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.

Contract performance, work performance information reflects directly on the workers, and should be available only to the parties directly involved. Hostile observers might use this information against any of the parties, either in competitive efforts or publicly. Incorrect or unavailable data will make it difficult to evaluate maintenance and construction team performance, which makes it difficult to manage those efforts, costing the road manager signficant time and money.

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 MCMC is not directly in front of the MCMC 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.

Maint and Constr Management Center Asset Management System asset status update Moderate Moderate Low
Linked to the asset inventory, so the same concerns with this flow as that one, namely that when placed in one spot becomes a "one stop shop" for a nefarious person looking for infrastructure targets. Given the narrow focus of this flow it might be LOW, except that it infers information about specific targets. Infrastructure information should be correct or maintenance assets may be inappropriately assigned. While this changes more than other asset flows, the impact should still be minimal.

Maint and Constr Management Center Maint and Constr Center Personnel maint and constr operations information presentation Not Applicable Moderate Moderate
System maintenance flows should have some protection from casual viewing, as otherwise imposters could gain illicit control over field equipment Information presented to backoffice system operators must be consistent or the operator may perform actions that are not appropriate to the real situation. The backoffice system operator should have access to system operation. If this interface is down then control is effectively lost, as without feedback from the system the operator has no way of knowing what is the correct action to take.
Maint and Constr Management Center Maint and Constr Vehicle OBE maint and constr dispatch information Moderate Moderate Moderate
Maintenance vehicle dispatch and routing information is predictive of maintenance vehicle location, and should be protected from hostile actors, as they may use this information for target acquisition or selection or damage assessment, for example. Maintenance vehicle dispatch instructions need to be correct and timely so that road maintenance activities are performed when and where they should be. Corruption of this information would cost time and money and may impact mobility.

Corruption of this information would cost time and money and may impact mobility.
Maint and Constr Management Center Maint and Constr Vehicle OBE maint and constr vehicle system control Moderate High Moderate
Control flows, even for seemingly innocent devices, should be kept confidential to minimize attack vectors. While an individual installation may not be particularly impacted by a cyberattack of its sensor network, another installation might be severely impacted, and different installations are likely to use similar methods, so compromising one leads to compromising all. Control flows, even for seemingly innocent devices, should have MODERATE integrity at minimum, just to guarantee that intended control messages are received. Incorrect, corrupted, intercepted and modified control messages can or will result in target field devices not behaving according to operator intent. The severity of this depends on the type of device, which is why some devices are set MODERATE and some HIGH. There should be multiple mechanisms for this information to arrive at the end recipient. If this is the only mechanism, should be raised to MODERATE.
Maint and Constr Management Center Storage Facility Data Acquisition System storage facility request Moderate Moderate Low
All observable information, but when placed in one spot becomes a "one stop shop" for a nefarious person looking for infrastructure targets. Infrastructure information should be correct or maintenance assets may be inappropriately assigned. Probably does not change very often, so the impact of loss of connectivity should be minimal.
Maint and Constr Management Center Traffic Management Center equipment maintenance status Moderate Moderate Moderate
Data is not overly sensitive, but is a bulk statement about the status of all field equipment managed by the maintenance center. A hostile actor could use this information in the commission of a crime, for instance by understanding which cameras were not working and thus what areas are not under surveillance. Center-based data exchanges are expected to be correct, and deserving of at leas some error checking. If this data is corrupted, the receiving center will be misinformed as to the state of field equipment maintenance. Depends on the update frequency required. Possibly LOW, depending on the amount of equipment and what this flow is used for at the terminus.
Maint and Constr Management Center Traffic Management Center special vehicle restricted use information Moderate Moderate Moderate
Contents of this flow enable specialized or elevated use of transportation facilities, which if copied could enable misuse of transportation assets. Incorrect data or unvailability will hamper legitimate maintenance, incident management and emergency use, which can have a significant effect. However, alternative means to allow those behaviors should already exist, at least for well marked emergency and safety vehicles, thus MODERATE and not HIGH.

While time reference should be universally available, time reference coupled with vehicle location is tracking data. This flow is internal to a vehicle, but should probably be encrypted to discourage hacking and snooping on the vehicle bus. Thus MODERATE. Location and time data is the basis for crash imminent safety and a host of other applications. Corruption of this flow could lead directly to a vehicle accident. If this information is not available, crash imminent safety applications depending on this information will not function properly.

Observation of control or status information is unlikely to have any value to a third party; actions of field personnel should be observable anyway. Any driver/operator interaction with vehicle systems needs some assurance of correctness; corruption of this information could lead to unexpected vehicle behavior which poses a limited safety risk. Without direct local control of vehicle systems the vehicle is essentially uncontrolled.
Storage Facility Data Acquisition System Maint and Constr Management Center equipment availability Moderate Moderate Low
Facility readiness, equipment readiness information can be deemed sensitive, as a hostile actor or criminal may want this information to enhance their ability to inflict damage. This information needs to be timely and accurate in order for construction and maintenance activities to meet their needs. This information needs to be timely and accurate in order for construction and maintenance activities to meet their needs. Typically won't change very rapidly, thus LOW availability.

Seemingly innocent, but as with most C2C flows there is little legitimate reason to make this observable; if this information was intended for more acecss, it would explicitly be provided to a wider audience. If this information is incorrect, the M&C Management Center may have an innacurate understanding of its materials supply status, complicating and/or jeopardizing effective road improvement and treatment operations. Depending on update frequency, may be LOW.
Surface Transportation Weather Service Maint and Constr Management Center transportation weather information Low Moderate Moderate
Typically intended for public distribution. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. In areas with severe weather it may be justifiable to raise this to HIGH. There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important. In areas with severe weather it may be justifiable to raise this to HIGH.
Traffic Management Center Maint and Constr Management Center equipment maintenance request Moderate Moderate Moderate
Device operational status information should be known only by those entities that need to know for operations and maintenance. Allowing others to read this information may enable abuse of those systems, 3rd party monitoring of system status when that may not be desireable, and reverse engineering of this and similar information flows. If this data is incorrect or unavailable then maintenance assets may not be appropriately assigned, resulting in inefficient use of maintenance assets and higher overall downtime.

Typically intended for public distribution. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. Even for areas with significant weather events that drive maintenance activities, it would be difficult to justify HIGH for this flow. While the repurcussions of inaccurate data may be significant, they are probably not catastrophic. M&MC relies on weather data for planning and decision making, so this flow needs to be reliable. In areas with flash-weather issues, this might be HIGH.
