Hitachi Energy recommends users disable Field Service Tool access and only enable it on an as-needed basis, such as for planned upgrades.

Hitachi Energy recommends the following general mitigation factors and security practices:

- Configure firewalls to protect process control networks from attacks originating from outside the network.
- Physically protect process control systems from direct access by unauthorized personnel.
- Avoid directly connecting control systems to the internet.
- Separate process control networks from other networks via a firewall system with minimal exposed ports.
- Users should not use process control systems for internet surfing, instant messaging, or email.
- Portable computers and removable storage media should be carefully scanned for viruses before connecting to a control system.
- Enforce proper password policies and processes.
