Cyberattacks on industrial control systems and in particular critical and manufacturing infrastructures is now a reality. Power generation facilities, metropolitan traffic control systems, water treatment systems and factories have become targets of attackers and have been hit recently with an array of network breach, data theft and denial of service activity. Service uptime, data integrity, compliance and even public safety require that organizations implement steps to deal with these security concerns. It is time to take action.VIEW CRITICAL INFRASTRUCTURE DOOMSDAY
Security devices for SCADA networks must often be installed in environments which are not friendly to standard IT equipment. In those cases it is essential for security devices to have robust mechanical design. Industrial specifications for dust, extreme temperatures, humidity, and vibration should be complied with to ensure physical durability. Rugged durable devices would have an extremely high MTBF (mean time between failures) and contain a minimum number of moving parts such as fans and hard drives.
