In cases where a software update is not possible, a reduction in the system’s network exposure is advised. Internet-accessible installations should be firewalled, whilst additional steps like network isolation by VLAN, IP filtering features of the devices and other technologies should be used to decrease the exposure of vulnerable systems. In addition the firewall on the hosts shall be activated and set according to BVMS and BIS configuration manual. For further informatation please check the published security advisory.
