Many data centers that support the cloud as well as commercial buildings have not adequately addressed control system cyber security. The lack of adequately addressing building control system cyber security was demonstrated to have caused very significant financial and potentially safety impacts. When you consider these control system cyber threats can affect multiple buildings, the insurance issues can become existential. Additionally, the use of multiple locations for data centers can be compromised by common network vulnerabilities from building operators and/or maintenance organizations. In this age where ransomware and hacking are rife, control systems need to be adequately addressed or it could be financially devastating to the building owners and insurance companies.
