The ongoing evolution of Artificial Intelligence (AI) and Machine Learning (ML) presents a pivotal transformation in the technology landscape. These versatile tools find utility across a vast array of applications. Notably, as AI advances, it is steadily establishing itself as a fundamental component of the security domain. AI’s role is twofold, encompassing both offensive and defensive applications. On one hand, it is leveraged to craft innovative and sophisticated attack strategies. Simultaneously, it is harnessed to construct robust defenses capable of countering these evolving threats. This dual nature of AI underscores its growing importance and dynamism within the realm of security. Two new technologies in the present world are cyber security and artificial intelligence (AI). This paper explores the critical role of Artificial Intelligence (AI) in addressing the ever-growing challenges of cyber security. With the rapid expansion of technology and the increasing number of cyber threats, traditional security methods have proven insufficient. AI, primarily through machine learning models, has emerged as a cornerstone in the field of cybersecurity. It provides solutions for user authentication, access management, behavior analysis, and spotting malware, botnets, and spam. This paper sheds light on the applications of AI in cybersecurity while acknowledging its potential drawbacks. As technology advances, it brings new security challenges, and AI can act a vital part in mitigating these challenges by rapidly adapting to evolving cyber threats. The paper discusses how AI can enhance cyber security by offering more efficient tools for identifying and responding to malware attacks, network intrusions, phishing, spam, and data breaches. It emphasizes the need for AI in coping with the complex and ever-changing landscape of cyber threats.
