For many critical infrastructure industries such as, water and wastewater, oil and gas, and power, SCADA has become the standard for system control and monitoring and offers significant benefits for reducing cost and increasing productivity. But industrial control systems have also become the targets of increasingly sophisticated cyber attacks. In the last twelve months, 54 percent of industrial companies have experienced an Industrial Control System (ICS) incident. This session will be valuable for anyone who has experienced a cyber security incident or is looking to take immediate protective measures while staying within a tight budget. And it will be especially valuable for those pursuing an upgrade to a more open SCADA software platform or replacing an outdated legacy PLC, RTU, or DCS.
