Cyber Attack insights Heli Tiirmaa-Klaar, Director of the Digital Society Institute at ESMT Berlin

A cyber-attack has never been qualified as an armed attack, but cyber operations will continue to be used to assist military goals, as we are witnessing in Ukraine. Applying cyber defence measures to defend critical digital assets, both military or civilian, should be an important part of any effective response strategy.

But what does constitute an armed attack in cyberspace?

Heli Tiirmaa-Klaar, Director of the Digital Society Institute at ESMT Berlin and previously Ambassador for Cyber Diplomacy and Director General for the Cyber Diplomacy Department at the Estonian Ministry of Foreign Affairs, acknowledges the answer varies depending on a country’s dependency on digital technologies, it’s cyber resilience and robustness of key infrastructures, and its cyber defence and offense posture.

Heli talks to Ronan about her background, when a cyber attack could be defined as an armed attack, the Estonian cyber attack in 2007, how to respond to cyber attacks and more.
