8 Common Firewall Mistakes Webinar Recording- Softprom Virtual Conference

Do firewalls prevent or enable cyberattacks? Find out in Mike Firstenberg’s recorded webinar – 8 Common OT/Industrial Firewall Mistakes from Softprom’s virtual conference


Firewalls are easy to misconfigure. While the security consequences of such errors may be acceptable for some firewalls, the accumulated risks of misconfigured firewalls in a defense-in-depth OT network architecture are generally unacceptable. We explore eight common mistakes that firewall administrators make and describe how these mistakes can compromise ICS network security. The lesson here though is not “stop making mistakes.” We also explore unidirectional gateway technology as an alternative to our most important OT firewalls that eliminates the potential for online attacks as a result of misconfiguration.
