4. MITIGATIONS

Hitachi Energy is developing PROMOD IV version 11.5, which will contain a patch to resolve the vulnerability. Hitachi Energy urges users to implement the following mitigations: 

  • Actbar2.ocx is no longer used by PROMOD IV. Users are encouraged to remove Actbar2.ocx.

Hitachi Energy recommends the following security practices and firewall configurations to help protect a process control network from attacks originating from outside the network: 

  • Physically protect process control systems from unauthorized direct access.
  • Separate process control systems from other networks using a firewall system with the minimal number of ports open.
  • Process control systems should not be used for internet browsing, instant messaging, or receiving emails.
  • PROMOD IV should be deployed inside the enterprise’s demilitarized zone (DMZ) network.
  • Portable computers and removable storage media should be carefully scanned for viruses before connecting to a control system
  • Users should follow the hardening guidelines published by The Center for Internet Security (CIS) to protect the host operating system.
