In today’s ever growing technological world, the protection of systems is needed and cybersecurity does just that. Cyber security is the field of prohibiting unauthorized users from accessing data, networks, and devices and keeping data safeguarded. AI or artificial intelligence plays a major part in this field since they can enhance the activities of humans more efficiently. Therefore, this paper deeply explores the specific positive and negative effects of cyber security and AI on businesses and individuals. This paper also dives deep into some tools of the field: CVE or common vulnerability and exposures and CVSS or common vulnerability scoring system. This leads the paper to discuss two major cyber incidents from JP Morgan and Chase and Microsoft Exchange Data Breach and the attacks used. These incidents displayed the need for a more vigorous cyber security. A few of the attacks these companies encountered and more types of attacks are explained in this paper as well. In addition, this paper informs about the specific effects cyber breaches can have on companies. This paper revealed that cybersecurity can positively affect businesses and individuals through mitigating attacks, securing data, making data accessible to only those who are allowed, and better quality of life and negative effects include high costs, more management, user inconvenience, constant new threats, and human error. The negative effects of AI include analyzing personal information, target vulnerabilities, mislead individuals, impersonate humans, and provide false information and positives include network intrusion detection products, threat hunting, vulnerability management, and data centers.
