The field of cybersecurity is witnessing rapid development thanks to artificial intelligence (AI) technologies, which play an increasingly important role in enhancing the protection of digital systems and networks. These technologies help detect suspicious activities, analyze user behavior, identify malware, and respond to security incidents quickly and effectively. On the other hand, AI has contributed to the development of cyberattack techniques, enabling the creation of more convincing phishing messages, the use of deepfake technology and voice cloning for identity impersonation, and the automation of vulnerability discovery and malware development. These threats are no longer limited to traditional systems but have also extended to AI models themselves, through attacks targeting training data, manipulating model outputs, and exploiting system vulnerabilities. Addressing these challenges requires comprehensive security strategies that combine modern technologies with human expertise. These strategies include verifying sensitive requests through independent communication channels, implementing multi-factor authentication, regulating the use of AI tools, conducting continuous security testing, and strengthening cybersecurity awareness and training. Artificial intelligence represents a double-edged sword in cybersecurity. While it offers advanced capabilities for strengthening digital defense, it also provides attackers with more sophisticated means of carrying out their attacks. Therefore, the responsible use of these technologies and the integration of technological innovation, human awareness, and effective security governance are essential to ensuring a safer digital environment.
