Measure: DiscreetAppearance


If possible, sensitive sites and buildings should be designed in a discreet appearance. Thus it shall be avoided that the sites or areas raise awareness of potential attackers. The aim is to lower the probability of attacks.


An example for a discreet design could be pumping stations. The building in which the pumps are located should not directly indicate that this is a pumping station for drinking water so that potential attackers are directly aware of a potential attack point. Also areas on a water utility's properties where for example servers or the control center are located should not be directly recognisable. This would quickly indicate an attractive attack point for a potential intruder.
