An introduction to operating systems in cybersecurity focuses on understanding how operating systems (OS) such as Windows, Linux, and macOS manage hardware, software, and system resources while also serving as a critical layer for enforcing security. In cybersecurity, the OS plays a vital role in protecting data through mechanisms like user authentication, access control, process isolation, and system monitoring. It is often the primary target for attackers, making knowledge of OS structures—such as kernels, file systems, memory management, and permissions—essential for identifying vulnerabilities and defending against threats like malware, privilege escalation, and unauthorized access. Understanding how operating systems function helps cybersecurity professionals secure systems, detect intrusions, and implement effective defense strategies.
