There is a variety of networks in a building that serve basic supply and disposal and thus form the basis for all business processes of an institution, including IT. Examples of such supply networks include:
- Electricity,
- Telephone,
- Cooling,
- Heating or ventilation,
- Water and wastewater,
- Fire suppression water systems,
- Gas,
- Alarm and control systems (e.g., for intrusion detection, fire, building automation), and
- Intercom systems.
The failure or disruption of a supply network can, among other things, result in people being unable to work in the building or in IT operations and thus information processing being impaired.
The networks are interdependent to varying degrees, so that operational disruptions in any single network can also affect others.
Examples:
- A failure of heating or ventilation can result in all employees having to leave the affected buildings. This can potentially cause high damage.
- Power supply failure affects not only IT directly but also all other networks equipped with electrically powered control and regulation systems. Even wastewater lines may have electrical lift pumps.
- Loss of water supply may impair the function of air conditioning systems.
