Abstract
Cyber threats are continuously evolving, increasing the need for advanced security technologies. Artificial intelligence (AI) plays an important role in cybersecurity by improving threat detection and enabling automated responses. This paper highlights recent advancements in AI-based cyber defense, focusing on machine learning and automation techniques. AI-driven security systems can analyze normal behavior patterns, identify threats accurately, and respond in real time. However, challenges such as lack of transparency, data bias, and adversarial attacks still exist
