This course introduces the core principles of configuration management and system hardening, two essential practices in modern IT operations and cybersecurity. Students will learn how organizations maintain consistent, secure, and reliable systems across servers, networks, and cloud environments.

The course begins with configuration management fundamentals, explaining how systems are standardized, tracked, and controlled to ensure consistency across infrastructure. Learners will understand how configuration management reduces human error, improves automation, and supports scalable IT operations in enterprise environments.

Students will then explore system hardening, which focuses on improving system security by reducing vulnerabilities and minimizing attack surfaces. The course explains best practices such as disabling unnecessary services, enforcing secure configurations, managing user permissions, and applying security policies across systems.

In addition, learners will discover how configuration management tools support automated system hardening, allowing organizations to enforce security policies consistently across large infrastructures. The course also connects these concepts to DevOps and IT operations, showing how automation improves both security and efficiency.

By the end of the course, students will have a strong understanding of how configuration management and system hardening work together to build secure and reliable IT systems. This course is ideal for beginners, system administrators, De
