SSL/TLS is the standard for securing communications over a network. There are clear security benefits of deploying SSL/TLS on your web servers and other applications requiring secure communication. However, there are many decisions to make when deploying SSL/TLS. This Lab teaches you about several areas you need to consider before getting hands-on practice with a variety of tools for working with SSL/TLS.

In this Lab, you will learn about SSL/TLS best practices and a variety of tools in the SSL/TLS toolkit to help ensure your deployments are configured they way you expect them to be. You will also use tools that help protect you as new vulnerabilities are discovered and the security landscape expands. AWS Cloud9 serves as the host and editor for this lab.
