Operating Systems & Server Security focuses on protecting servers and operating systems that power modern applications and infrastructure. This category teaches you how Windows and Linux systems work, where security weaknesses appear, and how attackers exploit misconfigurations and vulnerabilities in real-world environments.

You will learn core topics such as system hardening, user and permission management, patch management, secure configurations, service security, server monitoring, and log analysis. The courses cover securing Linux and Windows servers, preventing privilege escalation, protecting services, managing access controls, and implementing security best practices for on-premise and cloud-based server environments.

This category is ideal for system administrators, DevOps engineers, cybersecurity professionals, and IT practitioners who want to secure operating systems and server infrastructure. By mastering OS and server security principles, you’ll be able to harden systems, reduce attack surfaces, and protect critical infrastructure from real-world cyber threats.
