This video explains defense in-depth and its purpose.

This video demonstrates the different attackers that threaten software and systems. You will look at more foundational definitions.

This video provides an introduction to the SANS Top 25.

In this video, we will continue defining terms and start talking about security goals.

In this session, we will explore the fundamentals of APIs, their importance in modern web applications, and the basics of how they work.

What if you don't trust a single authentication method, such as a username and password pair? Then you can use multi-factor authentication, which is presented in this video.

In this video, we present a scenario that will be used throughout this chapter. Widget Makers needs an AWS solution and we're going to help them implement it with some solid design recommendations.

In earlier videos of this course, CloudWatch has been referenced. In this video, you will see what CloudWatch has to offer so that you can design for it well.

An additional factor is credential rotation. You will learn about this process and how to configure password rotation policies in this video.

There are important differences between Windows 10 Home, Pro, Pro for Workstations, and Enterprise. This video reviews the versions and feature differences.
