SU10: Center Maintenance

This service package supports maintenance of the computers, networks, video walls, and other information technology assets that are installed in a center to support center operations. Like other support service packages, this SP is drawn at a high level of abstraction so the basic interfaces and functionality associated with maintaining center IT assets can be applied to any center.

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.

Center	Service Monitor System	center status	High	High	High
Center	Service Monitor System	center status	System operational status information could be used to either initiate or confirm attacks, leading to significant downtime of related C-ITS systems.	System status information needs the greatest possible correctness, as if it is incorrect then inappropriate actions may be triggered that, for large backoffice and core systems, have widespread repurcussions.	Monitoring of system operational status has the highest possible needs for availability, as without an understanding of system state it is difficult to impossible to manage the system.
Center	Support Maintenance Equipment	center equipment status	Moderate	Moderate	Moderate
Center	Support Maintenance Equipment	center equipment status	The operational state of center systems, if known to an attacker or individual with criminal intent, could be used to facilitate the commission of a crime. Individual centers may be more or less important in this context; for example knowing whether a traffic management center is operating is probably more relevant to the criminal than knowing if a weather information center 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.

Center	Support Maintenance Equipment	service maintenance request	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, systems may not be repaired on time, resulting in inefficient use of maintenance assets and higher overall downtime.

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.
Support Maintenance Equipment	Center	center equipment commands	Moderate	High	High
Support Maintenance Equipment	Center	center equipment commands	Commands could be sensitive and should include authentication data, thus should be MODERATE.	Commands to Centers 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 center may be mis-configured or compromised. Considered HIGH as opposed to MODERATE because the operational scope of a Center is typically quite large compared to a Field device.	Without the ability to locally diagnose, operate, update and configure Center Equipment, the equipment is effectively out of control and would have to be taken out of service.

Support Maintenance Equipment	Center	center equipment configuration settings	Commands could be sensitive and should include authentication data, thus should be MODERATE.	Center system control, configuration and update need to be correct or the center may be misconfigured, which for some applications could have severe safety impacts. If the center has no safety-related functions, or little impact on regional mobility, this could be MODERATE.

Similarly, such software must be guaranteed to being the intent of the originator; not manipulated midstream or corrupted, or the roadway equipment may be mis-configured or compromised.
