OWASP Top 10 2025: Web App Security for Beginners (No Code) (Udemy.com)

+ Update with latest RC 2025!
+ Get instant access to FREE resources to scan your website
+ Easy to understand how-to videos!
+ Access to instructor if you ever get stuck!

Within 1,5 hour you will be able to explain web application security without having to code. For your convenience:

• I've combined the OWASP 2025, OWASP 2017, OWASP 2013 top 10 list into several sections with common web application security threats.

• I've updated the course with the latest threats added by OWASP in 2021.

• I've updated the course with the latest threats added by OWASP in 2025.

I will teach you the most common threats identified by the Open Web Application Security Project (OWASP).
 
Overview
1) Understand the OWASP top 10,
2) Explain impact per security threat, 
3) Understand these threats can be executed by attackers / pentesters / hackers
4) Explain how these security threats can be mitigated 

You will be able to understand the above-mentioned points without having to understand code. When implemented properly, it will decrease the impact of ransomware.

How is that possible?
The threats are explained conceptually, since the implementation of a threat may differ per situation. Therefore, having a general understanding of the security threats, its implications and potential solutions will provide you with the essential knowledge to mitigate the impact of these web application security threats. Hence, no security coding or security testing experience needed.
