SSL/TLS Operations

This course provides a comprehensive and practical deep dive into the concepts, architecture, management, and day-to-day operations of the SSL/TLS certificate ecosystem. It is designed to help you understand not only how SSL/TLS works, but also why its underlying security principles and operational practices matter.

You will learn how digital certificates establish identity and trust, how certificates are issued and validated, and how to perform essential operations such as certificate generation, installation, renewal, verification, revocation, and troubleshooting. Practical demonstrations throughout the course will help you apply these concepts confidently in real-world environments.

The course also reviews the evolution of SSL and TLS protocol versions, explains the security limitations of older protocols, and provides a detailed exploration of TLS 1.3. You will examine its streamlined handshake, improved performance, stronger cryptographic design, and enhanced security properties.

Advanced topics such as Certificate Transparency, Let’s Encrypt, and the Automated Certificate Management Environment protocol are also covered, giving you insight into modern certificate visibility, automation, and lifecycle management.

Although the course offers broad coverage of the SSL/TLS ecosystem, it includes focused content for website administrators, system engineers, DevOps professionals, SREs, developers, security practitioners, and solution architects. By understanding the reasoning and philosophy behind SSL/TLS, you will be better prepared to make sound architectural decisions, evaluate configurations, diagnose certificate-related failures, and troubleshoot complex security and connectivity issues across websites, servers, proxies, load balancers, and distributed applications.
