Protecting controllers from manipulation and unauthorised access

23 November 2020

If people, machinery and industrial processes are intelligently linked, these networks are also more susceptible to attack. The Pilz SecurityBridge hardware solution is designed to protect the configurable, safe small controllers PNOZmulti and the automation system PSS 4000 from network-based attacks and unauthorised access.

The SecurityBridge protects the connections between the programming/configuration tools and the hardware controllers from manipulation by detecting unauthorised changes to the automation project, for example. It acts as a firewall, but unlike generic firewalls, no complex configuration is needed. Thanks to application-specific default settings the device is easy to commission using the plug-and-play principle.

As well as benefiting from the security aspect, users also enjoy higher plant availability because only the data that is necessary (authorised configuration and process data) is transmitted.
