IoT and ICS Security

Security is now the hottest topic in the Internet of Things (IoT) and Industrial Control Systems (ICS), we might in fact want to call it generally the ‘Insecurity of Things’.

IoT and ICS can be seen as nothing more than remotely monitoring and controlling computer driven devices, the only difference being is the scale of the operation.

ICS is usually related to the control of industrial plants, whereas IoT generally refers to the more domestic applications of wearable technologies and household devices such as fridges.

Keeping IoT and ICS safe from attack

For both IoT and ICS the security principles are the same but IoT being a much newer technology and in many cases not designed with security in mind, the following should apply:

  • Protect data for confidentiality
  • Ensure data in not changed without detection
  • Need to authenticate the corresponding parties so data can be trusted

IoT and ICS are security related connected intelligences

IoT represents a world of computing device which are network connected and are monitored and/or controlled by other networked computing devices

ICS systems remotely monitor and control machinery and associated devices in industrial environments.

Unfortunately security is a pervasive attribute and cannot just be bolted on afterwards. ICS is a much more established technology that was generally built with security in mind. The problem here is that many of these systems are quite old and based on legacy components which are not necessarily easy to upgrade as seen recently with the NHS with the WannaCry ransom attack.

It doesn’t take much imagination to realise the damage that could result from a cyber-attack to any of these systems. Unfortunately, many people are unaware of the damage that can be done when these systems are attacked. Your very personal information may be stolen, your household internet system may be breached and whole industrial plants may be brought to a grinding halt.
