About the course:

Welcome to this Introduction to Application Security! Whether you are looking to lay down a solid foundation for a successful career in AppSec, or whether you're simply wanting to learn how to apply security best practices to your applications, this course is for you.

By learning how to navigate practical resources and frameworks, and by learning how to apply them to real-world applications, you will be well on your way to building more secure software. This course introduces concepts for web, mobile, and cloud apps so that you can gain exposure to all three and identify the specialty that you are most interested in.

In addition, we discuss top risks to defend against, including hands-on demonstrations of how attacks could be carried out against vulnerable applications.


While some basic programming experience is required to follow along, you definitely do not need to be a programming expert. All you really need is a strong desire to learn

  • What AppSec is, including skill requirements for current job opportunities
  • OWASP resources and the NICE Framework
  • Critical concepts of AppSec
  • Threat Modeling concepts and approaches

My name is Christophe Limpalair, and I have helped thousands of individuals pass IT certifications and learn how to use the cloud for their applications. I got started in IT at the age of 11 and unintentionally fell into the world of cybersecurity.

As I developed a strong interest in programming and cloud computing, my focus for the past few years has been training thousands of individuals in small, medium, and large businesses (including Fortune 500) on how to use cloud providers (such as Amazon Web Services) efficiently.

I've taught certification courses such as the AWS Certified Developer, AWS Certified SysOps Administrator, and AWS Certified DevOps Professional, as well as non-certification courses such as Lambda Deep Dive, Backup Strategies, and others.

Working with individual contributors as well as managers, I realized that most were also facing serious challenges when it came to cybersecurity.

Digging deeper, it became clear that there was a lack of training for Application Security specifically. As we explore in the course with actual research and data, most production applications in the world today contain security flaws that are identified as being in the top 10 risks by OWASP. Those security flaws can potentially be used to exploit organizations as we see in the news on a far too frequent basis.

It's time to take security into our own hands and to learn how to build more secure software in order to help make the world a safer place! Join me in the course, and we'll do just that!

I welcome you on your journey to learning more about Application Security, and I look forward to being your instructor!
