However, even from this abstract, it seems clear that “do no harm” is at risk due to this vulnerability. A mission essential function to that mission is each of the various medical devices works as expected, or at least if a device fails, it cannot actively be used to inflict harm. Unsolicited insulin delivery would mean that MEF “fails for a period of time longer than acceptable,” matching the description of MEF failure. The question is then whether the whole mission fails, which does not seem to be the case. The recovery of MEF functioning is not affected, and most MEFs (the emergency services, surgery, oncology, administration, etc.) would be unaffected. Therefore, we select [*MEF failure*](#mission-impact) and move on to ask about safety impact. This particular pilot study used SSVC version 1. -In the suggested deployer tree for SSVC version 2, mission and safety impact would be used to calculate the overall [*Human Impact*](#human-impat), and [*Utility*](#utility) would need to be answered as well. -Conducting further studies with the recommended version 2 Deployer tree remains an area of future work. +In the suggested deployer tree for SSVC version 2.1, mission and safety impact would be used to calculate the overall [*Human Impact*](#human-impat), and [*Automatable*](#automatable) would need to be answered as well. +Conducting further studies with the recommended version 2.1 Deployer tree remains an area of future work. In the pilot study, this information is conveyed as follows: - **Use of the cyber-physical system**: Insulin pumps are used to regulate blood glucose levels in diabetics. Diabetes is extremely common in the US. Misregulation of glucose can cause a variety of problems. Minor misregulation causes confusion or difficulty concentrating. Long-term minor mismanagement causes weigh management issues and blindness. Severe acute mismanagement can lead unconsciousness in a matter of minutes and death in a matter of hours. The impacted insulin pumps have a local (on-patient) wireless control, so wires to the pump do not have to be connected to the patient's control of the system, making the system lighter and less prone to be ripped out.
