If vehicles and the IT components used in them are not maintained and serviced or their functionality is not checked regularly, this can lead to them failing or only being operational to a limited extent when needed.

A major challenge here lies in the fact that updates for the IT systems integrated into vehicles are not necessarily available when vehicles have their regular maintenance cycles. This means, for example, that updates can only be installed sporadically and after some delay.

As a rule, vehicles and the IT components installed in them cannot be fully maintained or repaired in the respective organisation's own workshops, which is why they are often handed over to external companies. The vehicles are usually not monitored on the premises of the external companies, which means third parties can gain comprehensive access to a vehicle and its IT components. This increases the risk of misuse of the IT components or the theft of sensitive information.
