What's Happening?
The US Cybersecurity and Infrastructure Security Agency (CISA) and Australia's Cyber Security Centre (ACSC) have released joint guidance for isolating operational technology (OT) systems in critical infrastructure. The guidance aims to enhance cyber resilience
by detailing steps for isolating vital systems to ensure continuity of critical services during disruptions. It advises organizations to identify and classify systems, establish isolation points, and develop plans for operating in isolation. The guidance also addresses potential risks, such as reduced visibility and increased infection risk, and provides resources for improving preparedness and response.
Why It's Important?
As cyber threats to critical infrastructure increase, the ability to isolate and protect vital systems is crucial for maintaining service continuity and national security. The guidance from CISA and ACSC provides a framework for organizations to enhance their cyber resilience and mitigate the impact of potential attacks. By implementing these measures, critical infrastructure operators can better protect against disruptions and ensure the safe operation of essential services. This initiative highlights the importance of international collaboration in addressing global cybersecurity challenges.
