Understanding the trends, security concerns and state of the Industrial Control Systems (ICS) cloud helps pave the way. ICS with access to the cloud via web-enabled services are where IT and OT (Operational Technology) converge resulting in an integrated process and information flow that brings with it a more complex architecture. As ICS advances from communicating with networks within the enterprise to interacting externally via IoT platforms and the cloud, the efficiency, effectiveness and scalability improve. These advances create additional complexity and a larger attack surface which in turn has increased the opportunity for cyberattacks.
