Is Your OT Actually Isolated?
The CI-Fortify guidance, issued by cybersecurity authorities from the United States, Canada, UK and Australia, calls on critical infrastructure operators to prepare to isolate vital OT from other networks during a cyber emergency & keep critical operations running.
Take this self-assessment and in less than 5 minutes, you’ll get a clear picture of your OT isolation readiness and uncover gaps that could prevent you from keeping critical operations running during a cyber emergency.
What You’ll Learn:
- Ask the right questions about your OT isolation strategy
- Identify gaps that need further investigation
- Check whether critical dependencies have been accounted for
- See where your isolation plans and procedures need attention
- Prioritize what to test, validate or improve next
Frequently Asked Questions
What is OT network isolation?
OT network isolation is the separation of operational technology (OT) systems and networks from IT, the internet and other external networks. For critical infrastructure operators, isolation can help keep vital OT systems protected and operating during a cyber emergency affecting connected networks.
What is the CI-Fortify guidance?
CI-Fortify is joint guidance for critical infrastructure organizations developed by cybersecurity authorities from Australia, the United States, the United Kingdom and Canada. The guidance recommends preparing vital systems to operate independently during a serious cyber incident, including establishing isolation points between critical and non-critical networks and services.
Why should critical infrastructure operators test OT isolation?
An OT isolation plan may depend on people, procedures, IT systems, cloud services, remote access, telecommunications and other external services. Testing helps operators identify dependencies and gaps before isolation is required during a real cyber emergency.
