With its new firmware, the SecurityBridge firewall now offers comprehensive protection for industrial automation networks. Not only does it protect the configurable safe small controllers PNOZmulti and the automation system PSS 4000, it also now enables control over data communication between any other subscribers outside of the Pilz range. The SecurityBridge was developed in line with the secure development process in accordance with the standard IEC 62443-4-1 and also respects the principle of “Zones and Conduits”.
“Packet recording” has been added to the extensive diagnostic functions. This can be used to record data communication between subscribers from the secured controller network and the unsecured network. Recording can be restricted to specific communication relationships to enable you to analyse data more efficiently.
Physical access to machinery is clearly defined in the Machinery Safety Directive. For example, a safeguard on a gate ensures that a person cannot move within the danger zone until the machine is in a safe state. The SecurityBridge industrial firewall ensures that only authorised persons have access to the plant via the network. As a firewall it monitors communication with the controller and controls the data flow. You can also use SecurityBridge to store user rights; these define which staff members may access which data.
The GIT SECURITY AWARD is awarded nationally and internationally. Three innovative products with the most votes were selected from a total of six categories. SecurityBridge was competing in “Category A – IT-Security and Safety for Automation, Cyber Security”. It convinced our customers, partners, market players and readers of the magazines GIT SICHERHEIT, GIT SECURITY and messtec drives Automation and won through against 14 more finalists.
The SecurityBridge can be connected upstream of the PNOZmulti base unit, the PLC controller PSSuniversal PLC or any other subscribers outside of the Pilz range. The connection between PC and device is therefore protected. Only users with the relevant permission can make changes to a project’s configuration. This prevents unauthorised access to the secured network. In this way, data transmission between the Client PC and SecurityBridge is safe from eavesdropping and manipulation. http://www.pilz.com
