Russian Cyberwar in Ukraine

In its recent Insights note following escalating Russia/Ukraine tensions, the Cybersecurity & Infrastructure Security Agency (CISA) recommended clear steps to ensure that companies’ full response teams – including IT, communications, and legal – are prepared to act in the event of a critical cyberattack. CISA urged every organization in the US to "take urgent, near-term steps" to improve cybersecurity and resilience, which includes designating a crisis-response team and conducting tabletop exercises so all participants understand their roles and are ready to quickly and effectively respond to an incident. The organization’s guidance highlights a key aspect in an evolving geopolitical dynamic: business interests are very much at the table when tension emerges between states.
