Extending the secure edge in industrial control systems
Cyber security in industrial control systems (ICS) is poised to delay the adoption of Industry 4.0. Many business leaders find it hard to understand ICS cyber security challenges as there are many factors contributing to their complexity.

Enabling Industry 4.0 requires the factory to adopt new connectivity methodologies. This means that Ethernet has taken, and will continue to take, a larger role in industrial control systems. Analog Devices’ security strategy is to focus on where there is Ethernet connectivity because this significantly changes the impact any one device on the network has on the system. Our current family of industrial Ethernet solutions and TSN solutions has been the focus of our security development. In the near term, the fido5000, RapID Platform that provides 2-port, multi-protocol connectivity will be enabled with security features that provide key generation/management, secure boot, secure update, and secure memory access to protect against network bound attacks.

The product family roadmap includes single-chip solutions that feature a hardware root of trust, secure device lifecycle management, secure communications/mutual authentication, and tamper protection. As the industry continues to adopt sensors with increased intelligence, connectivity will extend lower in the factory driving additional security requirements at the device level. Analog Devices is committed to developing a secure portfolio that enables easier adoption of ICS security solutions and establish trust at the edge to accelerate the adoption of Industry 4.0.
