In the modern era, where technology is connected to all aspects of life, new challenges arise in cyberspace, making cybersecurity a key element in protecting data and systems from cyber threats. The complexity of cybersecurity challenges requires countries to collaborate in combating cyberattacks that transcend national borders. India and Israel possess highly developed cyber capabilities, with Israel becoming one of the world leaders in cybersecurity, particularly in defense and highly effective responses, while India excels in software development and advanced cybersecurity. Despite both countries having adequate cyber capabilities, they still face cybersecurity challenges. India and Israel, as countries that frequently face cyberattacks from both state and non-state actors, have raised awareness about the importance of cyber cooperation to protect national security and critical infrastructure. The theory used in this research is Network Security Theory. The research examines How do India and Israel collaborate in addressing cyber attack and what are the challenges of Indo-Israeli cooperation in implementing cybersecurity? As a result of this research, Israel and India are conducting their cyber defense, which includes the signing of a Memorandum of Understanding (MoU), CERT partnerships, joint cyber training, and the protection of critical infrastructure. However, the cooperation still faces challenges such as differences in policy approaches, lack of public awareness regarding cybersecurity, and geopolitical threats targeting the country from both state and non-state actors.
