The prevalence of cyber risks presents an ever-increasing threat to the security of networks, systems, and sensitive data in an era where digital connectivity rules. This study explores the complex field of cybersecurity with the goal of offering a thorough grasp of the tactics used to defend against cyberattacks.The first section of the study examines the historical background of cybersecurity, showing how it developed from simple computer security measures to the complex array of modern threats. The focus is on describing the wide range of cyberthreats, such as ransomware, phishing, and malware, and illustrating how they appear and what happens in the real world. A large amount of research is devoted to analyzing the vulnerabilities present in operating systems, networks, and data storage, providing insight into the complex interactions between technological flaws and human variables. The paper explores the role of human error as a crucial trigger for cybersecurity breaches in addition to clarifying the various attack surfaces.
