Website Security with Let's Encrypt and SSL/TLS Automation

In an era where web security is non-negotiable, running an unencrypted HTTP website leaves your users' data exposed and hurts your search engine visibility. Transitioning to HTTPS is the standard requirement for any modern web presence. This text-based course guides you through the process of securing your websites using Let's Encrypt. You will gain a clear understanding of public key infrastructure, learn how to automate certificate issuance, and configure popular web servers for maximum security. What you'll learn: - Understand the fundamentals of SSL/TLS, cryptographic handshakes, and how certificate authorities work. - Configure automated certificate generation and renewal using Certbot and ACME clients. - Secure web servers like Nginx and Apache with modern, high-performance HTTPS configurations. - Implement security headers and modern protocols like HTTP/2 for robust defense. - Troubleshoot common certificate errors, renewal failures, and mixed-content issues. - Apply modern zero-trust security principles to transport-layer encryption. You will start with the core concepts of web security and encryption before moving step-by-step through server configuration, automated renewal pipelines, and security verification. This course is designed for beginner system administrators, web developers, and site owners who want to secure their web servers, with no prior cryptography experience required. Start reading today to secure your web traffic and protect your users with modern HTTPS.
