A firewall is one of the most critical security appliances in an Operational Technology (OT) environment. The OT firewall validation is the process of testing, verifying, and optimizing the configuration and functionality of firewalls in OT environments to ensure they enforce security policies, protect critical systems, and operate reliably within the specific constraints of OT networks. These systems often support essential infrastructure, where vulnerabilities can lead to downtime or even catastrophic consequences.
When it comes to firewall rules, several common misconceptions and errors can compromise the effectiveness and security of your OT systems.
Common firewall rule misconceptions
- “Our effective IT firewall rules will be equally effective for our OT systems.”
- “We have a firewall, so our OT systems are secure.”
- “The default firewall rules are adequate.”
