Linux Web Server Hardening and Security Fundamentals

Operating a public-facing web server means constantly defending against automated scans, brute-force attacks, and unauthorized access attempts. This comprehensive text-based course guides you through the essential steps to harden your Linux web servers, transforming them from vulnerable defaults into highly secure, resilient environments. What you'll learn: - Learn the core principles of server hardening and the zero-trust security model. - Configure robust firewalls using modern tools to restrict unauthorized network traffic. - Secure SSH access by disabling password authentication and implementing key-based logins. - Implement basic intrusion detection and automated log monitoring to spot suspicious activity early. - Apply secure permissions and user privilege management using the principle of least privilege. - Keep your system resilient with automated security updates and vulnerability scanning practices. You will start with fundamental security concepts and terminology before moving step-by-step through practical configuration examples, command-line tools, and real-world hardening scenarios. This course is designed for beginner Linux administrators, web developers, and system operators who want to protect their online infrastructure. No prior security experience is required.
