OWASP Top 10 2025

This course contains the use of artificial intelligence. Led by Dr. Amar Massoud, a seasoned expert with decades of academic and professional experience, it combines cutting-edge AI support with human insight to deliver content that is precise, practical, and easy to follow. You’ll gain the clarity of structured learning and the confidence of being guided by a recognized authority.

The OWASP Top 10 is the most trusted and widely referenced standard for application security risks, and the 2025 edition reflects today’s rapidly evolving threat landscape. This course provides you with a comprehensive, hands-on understanding of all ten categories — from Broken Access Control and Cryptographic Failures to Server-Side Request Forgery (SSRF) — and teaches you how to recognize, analyze, and prevent these vulnerabilities in real-world environments.

Throughout the course, you’ll learn by combining theory with practice. Each section explores a specific OWASP Top 10 category, explains its relevance, and demonstrates its impact using case studies from recent breaches. You’ll also practice applying OWASP-recommended controls through assignments, exercises, and solution walkthroughs, reinforcing your ability to connect security concepts with real-world systems.

We’ll explore how these vulnerabilities affect modern applications — including web, API, cloud, and mobile platforms — and discuss practical mitigation strategies such as secure design patterns, backend validation, encryption standards, API security testing, secure configuration, and supply chain protection. You’ll discover how to apply defensive programming techniques, conduct security assessments, and implement monitoring practices that catch attacks early.

By the end of this course, you will:

• Understand all OWASP Top 10 (2025) risks and their real-world consequences

• Learn how to identify vulnerabilities in code, APIs, and configurations

• Gain practical strategies to mitigate and prevent common security flaws

• Be able to analyze case studies and map breaches to OWASP categories

• Strengthen your ability to design and build secure applications

Whether you are a developer, security professional, IT manager, compliance officer, or student seeking to build expertise in application security, this course gives you the knowledge and skills to protect systems against the most critical threats of 2025.
