Understand what secures your internet, not just that it does
TLS secures everything: your bank login, email, video calls—any data crossing the internet that shouldn't be readable to observers. This course grounds you in how it works and how to deploy it. You'll trace the evolution from Netscape's SSL through modern TLS, understanding why naming conventions matter. The hands-on focus: planning and deploying a public key infrastructure (PKI) that issues, manages, and eventually retires certificates across your environment. Both Windows and Linux get coverage, since real infrastructure spans operating systems. Hashing ensures data hasn't been tampered with; digital signatures prove identity. Certificate management—the practical glue holding everything together—gets thorough treatment. This isn't abstract cryptography; it's the operational work of keeping encrypted channels alive. For anyone managing systems, applications, or security, understanding TLS moves it from 'something that just works' to 'something you can confidently troubleshoot and maintain.'
About this course
Transport Layer Security, or TLS, is a widely adopted security protocol designed to facilitate privacy and data security for communications over the Internet. A primary use of TLS is encrypting the communication between web applications and servers, such as web browsers loading a website. TLS can also be used to encrypt other communications such as email, messaging, and voice over IP (VOIP).
TLS evolved from a previous encryption protocol called Secure Socket Layer (SSL), which was developed by Netscape. TLS version 1.0 actually began development as SSL version 3.1, but the name of the protocol was changed before publication in order to indicate that it was no longer associated with Netscape. Because of this history, the terms TLS and SSL are sometimes used interchangeably.
In this course, you will learn the skills you need to plan, implement, and maintain a public key infrastructure (PKI) ecosystem that supports SSL/TLS security certificates.
We'll get into how to install and configure PKI solutions in both Windows and Linux. Learn about how certificates are issued and managed throughout their lifetime; how hashing provides integrity and digital signatures provide authentication and much more in this course.
