The “Forgotten” OT/ICS Endpoints – How to Demonstrate Measurable Improvement in OT/IC Security

Presented by CEO John Livingston during SANS Industrial Forum

Firewalls are easy to misconfigure. While the security consequences of such errors may be acceptable for some firewalls connecting data and information networks, 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.’ The lesson is to choose the appropriate technology for the need. We explore technology alternatives to OT firewalls that eliminate the potential for online attacks as a result of misconfiguration.
