Supervisory control and data acquisition (SCADA) and industrial control systems have long been considered immune to cyberattacks on corporate information systems.
The move toward open standards such as Ethernet TCP/IP and web technologies has seen control systems affected by an increasing number of malicious and non-malicious network security events affecting critical infrastructure and manufacturing industries.
You may never be attacked by a serious hacker, but control networks are extremely vulnerable to simple, everyday security and reliability issues. Human error, poor network segmentation, and unprotected network entry points—soft targets like unpatched PCs and vulnerable PLCs—can lead to significant production losses and even security issues.
