product description

The network security requirements for operatorsĀ of public supply and disposal facilities require new solutions. mGuard is a router for secure data connections (VPN) with a firewall that can provide detailed adjustment. With the help of this router, the control system/control network (PLC) can be
specifically isolated from the Internet. Accesses to public areas of the Internet from inside and outside are blocked. This protects the critical infrastructure. Secure communication connections (VPN tunnels) are used to ensure that the on-call service personnel can access the system. The VPN tunnel for
the on-call service is permanently available, while the VPN tunnel to the remote maintenance centre of the wks group is opened by the operator when required. It can be switched on and off using a:

  • button in the visualization system
  • button in the control panel
  • hardware switch
  • script in the computer

Furthermore, mGuard can also check the system integrity. In this process, all files which may potentially contain viruses are checked for changes and, if necessary, an alarm is issued to the system administrator.
