Russia has deployed cyber operations to interfere in foreign elections, launch disinformation campaigns, and cripple neighboring states-all while maintaining a thin veneer of deniability and avoiding strikes that cross the line into acts of war. How should a targeted nation respond? In Russian Cyber Operations, Scott Jasper dives into the legal and technical maneuvers of Russian cyber strategies, proposing that nations develop solutions for resilience to withstand future attacks. Jasper examines the place of cyber operations within Russia’s asymmetric arsenal and its use of hybrid and information warfare, considering examples from French and US presidential elections and the 2017 Not Petya mock ransomware attack, among others. A new preface to the paperback edition puts events since 2020 into context. Jasper shows that the international effort to counter these operations through sanctions and indictments has done little to alter Moscow’s behavior. Jasper instead proposes that nations use data correlation technologies in an integrated security platform to establish a more resilient defense. Russian Cyber Operations provides a critical framework for determining whether Russian cyber campaigns and incidents rise to the level of armed conflict or operate at a lower level as a component of competition. Jasper’s work offers the national security community a robust plan of action critical to effectively mounting a durable defense against Russian cyber campaigns.
