What you'll learn

  • Understand the OWASP Top 10:2025 vulnerabilities and how modern web application attacks work in real-world scenarios
  • Perform practical attacks like SSTI, Broken Access Control, Injection, and Authentication Bypass in hands-on labs
  • Learn how attackers identify, exploit, and abuse insecure web application functionality and misconfigurations
  • Understand how developers can prevent common web security vulnerabilities using secure coding and security best practices

Course content

1 section • 11 lectures • 1h 13m total length

  • Introduction to OWASP Top 106:35

    Explore the OWASP top 10 2025 vulnerabilities, learn how attacks exploit them, and master practical prevention and mitigation techniques for modern web apps.

  • Broken Access Control3:35

    Explore broken access control, where normal users access admin functions due to missing server-side checks; the lab shows an unprotected admin panel and highlights role-based access control and endpoint testing.

  • Security Misconfiguration3:10

    Explore security misconfiguration, a common web issue where misconfigured settings expose data. Learn to prevent it by disabling debug in production, returning generic errors, removing unnecessary services, and testing configurations.

  • Software Supply Chain Failures5:19

    Understand how software supply chain failures from outdated third-party libraries can compromise apps, as seen in SolarWinds, and learn how insecure dependencies and exposed debug features reveal sensitive information.

  • Cryptographic Failures5:12
  • Injection Attacks4:36

    Example SSTI Payload Covered in the Course:

    {{cycler.__init__.__globals__.os.popen('cat flag.txt').read()}}

  • Insecure Design7:19

    Learn how insecure design arises when security is ignored in planning and architecture, allowing attackers to abuse business logic and bypass authentication, with threat modeling and server-side validation.

  • Authentication Failures8:58

  • Software or Data Integrity Failures12:19

    Protect software and data by enforcing digital signatures and integrity checks for updates, dependencies, and serialized data; secure CICD pipelines, vet third-party libraries, and validate all inputs.

  • Security Logging and Alerting Failures9:33

    Explore security logging and alerting failures in the OWASP 9th vulnerability. Learn to log authentication events, monitor suspicious activity, and trigger real-time alerts to detect breaches.

  • Mishandling of Exceptional Conditions7:01
  • quiz

Requirements

  • No prior web security experience is required. Basic knowledge of web applications and browsers is helpful, but everything is explained step by step in a beginner-friendly way.

Description

In this course, you will learn the OWASP Top 10:2025 through practical web security demonstrations and hands-on labs. The course is designed for beginners who want to understand how common web application vulnerabilities work in real-world environments.

We will cover major security risks including Broken Access Control, Security Misconfiguration, Software Supply Chain Failures, Cryptographic Failures, Injection attacks, Insecure Design, Authentication Failures, Software or Data Integrity Failures, Security Logging and Alerting Failures, and Mishandling of Exceptional Conditions.

Throughout the course, you will learn how attackers identify and exploit vulnerabilities in web applications while also understanding how developers can secure applications against these attacks. Each topic is explained in a simple and beginner-friendly way with practical examples and demonstrations.

This course focuses on practical understanding with clear explanations and hands-on demonstrations. You will explore vulnerable applications, real attack scenarios, and practical techniques commonly used in ethical hacking and web application security testing.

By the end of this course, you will have a strong understanding of the latest OWASP Top 10:2025 vulnerabilities and how they impact modern web applications effectively.
