The rise of automation in operations poses high-security risks to organizations in the water sector. A large number of cyber-attacks towards water sector companies involved both outsider and insider threats. Outsider threats are external attacks towards internal systems through misconfigurations, unauthorized access, and vulnerabilities on devices that are caused by unpatched, outdated or unsupported software, especially towards SCADA systems. Meanwhile, insider threats happened frequently, not just through negligence such as accidental data breaches, but also ones with malicious intent. For example, a disgruntled ex-employee or bribed current employee plugged in an unauthorized USB and infect the machinery with ransomware, or install malicious software in a trusted host, creating a backdoor that allows external threats to connect to the internal network.
