It is often more efficient to use an office for small or short meetings. In doing so, however, visitors could view internal information, jeopardise business processes, and manipulate IT systems in various ways. The same applies to cleaning and other third-party personnel. The possible threats range from improper handling of technical equipment and attempts to “play” with IT systems to the outright theft of documents or IT components. For example, cleaning staff can accidentally loosen a plug connection or water can get into IT equipment. Documents can also be misplaced or even disposed of as waste.
