Sensors for ICS components in industrial environments are frequently subject to particular conditions that affect their secure operation. Examples of this include extreme heat, cold, humidity, dust, vibration, or atmospheres with a corrosive or caustic effect. In many cases, several of these factors are present simultaneously. Such harmful environmental impacts may result in the sensors of ICS components wearing more rapidly, failing earlier, or producing incorrect measurements.

Information security is often not considered during procurement and installation due to a lack of risk awareness or for cost-related reasons. Sensors might thus include serious vulnerabilities that can only be addressed with significant effort later on.
