Secure TLS Configuration for Data in Transit

In an era of increasing cyber threats, securing data as it moves across networks is a fundamental requirement for any modern system. Implementing Transport Layer Security (TLS) correctly is critical to preventing eavesdropping, tampering, and man-in-the-middle attacks. This text-only course guides you through the foundational concepts of encryption in transit, helping you transition from basic network setups to highly secure, modern TLS configurations. You will learn to evaluate cipher suites, manage cryptographic keys, and align your infrastructure with zero-trust security principles. What you'll learn: Understand the fundamentals of symmetric and asymmetric encryption within the TLS handshake; Configure web servers to support secure TLS 1.3 and TLS 1.2 protocols while disabling obsolete versions; Manage cryptographic keys and certificates safely using automated renewal workflows; Apply modern cipher suites to ensure perfect forward secrecy and strong data integrity; Test and audit your TLS configurations using standard command-line diagnostic tools. The course starts with essential cryptographic terminology and handshake mechanics, then progresses to step-by-step configuration examples and validation exercises. You will work through written scenarios to build a robust, production-ready encryption strategy. This program is designed for systems administrators, developers, and aspiring security professionals who want to understand encryption in transit. No prior cryptography experience is required.
