Course Description

Welcome to the OWASP Top 10 deep dive course where you will learn in full detail, the top ten vulnerabilities that applications face today.

The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications and has become such an important cyber security resource today.

Unlike other courses that take a lazy approach to describing these security risks, this course analyzes each vulnerability in full detail by describing

  • What exactly the vulnerabilities are

  • How they are exploited by attackers

  • How they can be prevented

  • Real world cases and scenarios where such vulnerabilities have been exploited

  • Practical demonstrations of the exploits where possible

We will be making use of some third party applications where applicable to perform some practical examples of some of these vulnerabilities.  I will also describe real world cyber attacks that have exploited some of these security risks whenever possible to add some more context.

We will also make use of some third party applications to try out some of these security risks and see how they are actually exploited in a real cyber attack.

I hope to see you inside the course.

Alex.

La forma en la que se expresa el instructor hace que las clases no se tornen aburridas, se nota que conoce muy bien los conceptos aborda y los ejemplos que usa ilustran muy bien los problemas, aunque hay algunos ejemplos que pudieran ser no muy claros debido a la falta de familiaridad con los temas de seguridad, aun así, investigando un poco más sobre el ejemplo dado se llega a una comprensión de ello, buen curso.

By Allan Prevosaperalta1 on 8/24/2026

The course allows me to understand more about the OWASP, very clear instructions and information. Very engaging and the instructor is good moderator.

By Phua Niamlee on 8/23/2026

It is full of vulnerabilities that I am not aware of and it really helps me very much to understand and beware of such vulnerabilities.

By Carlos Francisco Alcantar Salinas on 8/9/2026

Porque estuvo bien dirigido, con lo más importante y de forma directa y concisa y bien explicado con ejemplos fácilmente entendibles.

By Marisol Martinez Espino on 8/6/2026

Bien explicado, muy ameno y aprendes con ejemplos reales también. De repente puede ser confuso porque las vulnerabilidades se parecen o están relacionadas.

By Sergio Armando Cervantes Bonilla on 8/6/2026

Muy buen curso, como mejora sería bueno considerar secciones donde se hagan preguntas de opción multiple donde se refuercen conceptos abordados en la lección.

By Monicofrancis Battungdolo1 on 7/31/2026

Mixed as currently we are in the middle of a major upgrade and it is all vendor released application and it is only internal enterprise and not internet facing applications.

By Jiehuijackie Li1 on 7/29/2026

The instructer has a very engaging energy that helped me to understand the security of the programming platform and system

By Jeremy French on 7/23/2026

Presenter seems very animated and companionable, but clearly understands some aspects better than others. Strange emphasis on irrelevant details if you actually already know the topic he's talking about.

By Mahavir Kumbharvadia on 6/28/2026

This course gives a detailed analysis of each security risks with examples and how it should be prevented. I am looking forward to exploring more from this author.
