The term "cyber security" refers to the process of protecting computer networks from malicious online attacks or unauthorized access. Cyber security solutions are essential for organisations, enterprises, and governments due to the pervasive danger posed by cyber criminals. AI has immense potential as a viable solution for addressing this issue. By using the capabilities of artificial intelligence, security specialists can enhance their ability to protect susceptible networks and data from cyber assailants. This article provides an overview of the use of AI in the field of cyber security. AIdriven cyber security utilises AI and machine learning technology to enhance the safeguarding of computer systems and networks against cyber threats, including hacking, malware, phishing, and other types of assaults. AI-driven security solutions are specifically developed to automate the identification, examination, and handling of security breaches in real-time, thereby enhancing the efficiency and efficacy of cyber security. These systems provide the capability to process vast quantities of data, detect patterns and irregularities, and make prompt and precise choices, beyond the abilities of people alone. This enables organisations to proactively address emerging cyber risks.
