Cyber insecurity poses a significant threat to a country’s national security by exposing vulnerabilities in critical infrastructure, enabling espionage, promoting disinformation campaigns, and hindering cyber warfare capabilities. In order to strengthen asymmetric deterrence against Iran, cyber warfare capabilities are increasingly taking a prominent place in Israel’s strategic thinking and national security doctrine. In contrast, Iran, relying on its conventional-cyber capabilities, adopts a hybrid strategy to prevent cyber insecurity. However, the October 7 incident changed the geopolitical situation in the Middle East. One of the notable consequences of the October 7 incident was the Israeli-Iranian war. As a result, the recent Iran-Israeli war, which has extended into the realm of electronic warfare, is the result of technological advances, the complexity and sensitivity of the conflict, and the efforts of both sides to gain superiority at the lowest cost and with the greatest effectiveness. While Israel leveraged its advanced cyber units such as Unit 8200 and the coordination of national intelligence agencies to conduct precision cyber offensives, Iran utilized its hybrid model—combining conventional and cyber tactics—to retaliate and demonstrate resilience under pressure. As the article concludes, this confrontation illustrates the emergence of a new warfare paradigm in which information is as powerful as weaponry, and control over digital systems has become central to national power. The Iran–Israel cyber conflict is therefore a microcosm of a broader transformation: modern wars are increasingly multi-domain, fought simultaneously in physical, psychological, and cyber spaces.
