Security of SCADA (supervisory control and data acquisition) and other industrial control systems (ICSs) is a complex subject, and one that has received much attention in recent years. While modern industrial control systems use many of the same computers, operating systems and networking components as conventional business networks, the two kinds of networks are managed very differently.

Like all major factories, pharmaceutical production is heavily dependent upon control systems. Complex machinery is responsible for the recipes and the quantities. Safety and reliability are key at such sites. One small, unauthorized alteration can seriously risk public safety. How can we let hackers control the recipes of the medicine we or our children take?

Business networks are under constant attack. How do professionals deal with this constant, pervasive threat? In part, they deal with it through constant, aggressive change. “Stay ahead of the bad guys.” Update antivirus signatures several times per day. Apply the latest vendor security updates within two days of the vendor’s release.

This is the exact opposite of how control system networks are managed. Control system networks are generally configured to be unable to exchange information directly with the Internet, and so are not under constant attack. The biggest risk to industrial networks is the connection to the business network.

Waterfall Security Solutions’ Unidirectional Security Gateways offer a solution which increases confidence in protection of safety, integrity and availability of the operations network. The gateways are a hardware-based solution which permits information to flow out of the operations network, without allowing any attacks, messages or information back in.
