Professional and regular remote maintenance is required to ensure the security and proper functioning of IT systems and applications than can only be accessed remotely. If IT systems and applications are not properly configured and maintained via remote maintenance, they will (in the worst case) no longer be usable. If remote maintenance processes do not run correctly, this can lead to malfunctions of individual operating system components. Moreover, vulnerabilities may occur because of IT system maintenance work that is carried out too late or improperly.
