The integration of artificial intelligence (AI) into cybersecurity frameworks offers immense potential for proactive threat detection and mitigation. However, this advancement also presents significant challenges, including the potential misuse of AI in cyberattacks. After a brief introduction to the dual-use nature of AI from a cybersecurity perspective, this policy brief argues for a collaborative approach among G7 nations to address these challenges and maximise the benefits of AI in cybersecurity. It makes recommendations for improving information sharing, establishing common standards, ensuring the trustworthy operation of AI systems, and engaging the young developer community.
