4. MITIGATIONS

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

  • Physically protect process control systems from unauthorized direct access.
  • Separate process control systems from other networks using a firewall system with only the necessary ports open.
  • Process control systems should not be used for common internet activities.
  • Portable computers and removable storage media should be carefully scanned for malicious software before connecting to a control system.

Hitachi Energy also recommends following the hardening guidelines published by The Center for Internet Security (CIS) to protect hosts connected with MSM. This measure will prevent the lateral movement of the attack vector into MSM via such connected devices. Examples for Windows computers include:
