General security recommendation is coming from ABB Security team:

Control systems and the control network are exposed to cyber threats. In order to minimize these risks,
the protective measures and best practices listed below are available in addition to other measures. ABB
strongly recommends system integrator and asset owners to implement the measures they consider
appropriate for their control system environment:
– Place control systems in a dedicated control network containing control systems only.
– Locate control networks and systems behind firewalls and separate them from any other networks
like business networks and the Internet.
– Block any inbound Internet traffic destined for the control networks/systems. Place remote access
systems used for remote control system access outside the control network.

– Use trusted, patched software and malware protection solutions. Interact with trusted web sites and
trusted email attachments only.
– Ensure all Freelance products are always up to date in terms of installed software, operating system
and firmware patches as well as anti-virus and firewall.
– Protect control systems from physical access by unauthorized personnel e.g. by placing them in
locked switch cabinets.
