The Department of Homeland Security (DHS) has identified 16 critical infrastructure sectors “that are so vital to the United States that their incapacity or destruction would have a debilitating impact on our physical or economic security or public health or safety.” CyberLock access control systems provide full-featured access control to every locking point, whether inside or outdoors. Water and Wastewater Treatment facilities are considered by the Department of Homeland Security to be critical to the health and safety of the public.Therefore, strict security guidelines and protective measures have been implemented in this sector. Mechanical locks and keys and hardwired access control systems do not suit this industry due to the costs, challenges, and limitations. CyberLock electronic locks and keys combine the benefits of both systems, providing an ideal solution for Water and Wastewater treatment facilities.
