Hitachi ABB Power Grids reported this vulnerability to CISA.
Hitachi ABB Power Grids recommends users update to Version 6.3.1 or later.
Hitachi ABB Power Grids also recommends implementing security best practices and firewall configurations, which help protect a process control network from attacks that originate from outside the network. Such practices include:
- Ensuring critical applications and systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall.
- Firewalls should be configured to have the minimum number of ports exposed and open ports should be justified and documented.
- Critical systems should not be used for Internet surfing, instant messaging, or receiving e-mails.
- Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system.
- It is important to implement robust security awareness training to ensure users can identify common attacks or content such as phishing emails or malicious webpages.
