IND.2.3 Sensors and Actuators

Introduction

Sensors are electronic components featuring a microprocessor and software that serve as measuring transducers capable of converting a physical magnitude into an electrical output value. This value is provided as a standardised unit signal (often 4 to 20mA, 0 to 10V) to a serial interface, or as digital information transmitted via a fieldbus or Ethernet protocols. Along with measurements, measuring transducers often provide interfaces for performing diagnosis and parametrisation. In addition to producing electronic output values, a sensor may also have further interfaces, such as WLAN, Bluetooth, or wireless HART interfaces for parametrisation and diagnosis.

There are many different sensors available on the market (e.g. for measuring physical values). Depending on the task at hand, the functions and performance of a sensor vary significantly. The range includes sensors that only provide measurements and do not need to be configured. However, some also allow calibration, configuration, or pre-processing of data, or even complete signal processing (smart sensors).

Objective

The aim of this module is to protect all types of sensors regardless of their manufacturer, type, purpose, and place of use. It can be applied to an individual sensor or a combined sensor assembly.

Scoping and Modelling

Module IND.2.3 Sensors and Actuators must be applied once to sensors and actuators.

It must be used to protect sensors. It supplements the generic module IND.2.1 General ICS Components, which is a prerequisite of the present module.

Simple sensors that do not have configuration interfaces or more complex processing logic are not covered by this module. The potential protective measures for such sensors are limited to securing access to them and monitoring whether they are active.

The module also does not address the protection of complex wireless sensor networks. It only describes the protection of individual sensors. It does not describe the security requirements for process control and automation technology. On this subject, module IND.1 Process Control and Automation Technology must be implemented.

1. Pregled

IND.2.3.A1 Installation of Sensors [OT Operations, Maintenance Personnel] (B)

Sensors MUST be appropriately installed and be sufficiently robust. They MUST be able to provide reliable measurements despite extreme environmental conditions related to heat, cold, dust, vibration, or corrosion.
IND.2.3.A2 Calibration of Sensors [Maintenance Personnel] (S)

If necessary, sensors SHOULD be calibrated regularly. Calibrations SHOULD be documented appropriately. Access to a sensor's calibration functions MUST be protected.
IND.2.3.A3 Wireless Communication (H)

Wireless management interfaces such as Bluetooth, WLAN, or NFC SHOULD NOT be used. Any unused communication interfaces SHOULD be disabled.
