Configuring Firewalls for OT Networks
Configuration, testing and commissioning of firewalls for OT networks
What is the function of a firewall?
Firewalls are networked devices consisting of hardware and/or software for segmenting networks and preventing unauthorized access to critical ICS assets. However, a firewall is only as good as its configuration. Proper configuration of firewalls requires not only a skilled operator trained on the particular brand of firewall but also requires considerable understanding of process control network, industrial protocols and control system applications. Small mistakes can render a firewall worthless as a security appliance.
aeSolutions has extensive experience in designing, configuring and commissioning firewalls in industrial applications. We have experience in all major brands of firewalls, whether they be general-purpose IT firewalls used to segregate the ICS networks from company business networks or industrial firewalls used to protect individual zones and conduits. Our team has experience with firewalls from a variety of manufacturers such as Tofino, Phoenix Contact mGuard, Cisco ASA, SonicWall, Siemens Scalance, Downstream, etc.
