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:
o 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.
o Firewalls should be configured to have the minimum number of ports exposed
and open ports should be justified and documented.
o Critical systems should not be used for Internet surfing, instant
messaging, or receiving e-mails.
o Portable computers and removable storage media should be carefully scanned
for viruses before they are connected to a control system.
o 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.
