Carelessness and a lack of security awareness when handling vehicles and their components pose a serious danger. If employees are not adequately trained on how to handle vehicles and their IT components, for example, or not aware of the possible risks, this can lead to improper use. For example, IT systems on the bridges of ships are used by different people. If a user changes essential settings without informing the other users, malfunctions could occur that the other users cannot understand.

Vehicles that are not properly locked present another threat. This could allow unauthorised third parties to simply enter a vehicle's cabin and view or steal all the IT components and stored information therein.

Furthermore, poorly trained staff could react inappropriately to faults and make the situation worse. If a user attempts to remedy a malfunction in a vehicle's integrated IT systems rather than contacting the responsible department, this could result in unforeseeable consequences. For example, relevant settings for security or data protection could be changed.
