Cyber attacks have been carried out by both sides in the Ukraine-Russia war to neutralize national infrastructures, banking systems, and government ministries; influence decision-makers, citizens, and soldiers; and gather intelligence. Cyber played no real role in disabling national capabilities or infrastructure, but has had psychological and cognitive effects. The first year of the war sharpened the need to build and upgrade information security measures, especially around critical national infrastructure; strengthen real-time information-gathering capabilities from social networks; strengthen awareness; and maintain information security.
