Course details
The OWASP Top 10 is the cybersecurity industry's most recognized framework for web application security risks, and understanding it is essential for anyone building modern software. In this beginner-friendly course, learn the 2025 edition through clear explanations, real-world breach case studies, and actionable prevention techniques. Join application security expert Caroline Wong as she breaks down each of the 10 vulnerability categories, explains how attackers exploit them, and outlines practical steps you can take to prevent these risks in your own applications. Along the way, discover how to integrate OWASP Top 10 security practices throughout the secure software development lifecycle and prioritize defenses based on your organization's needs. By the end of this course, you'll be equipped with the skills and confidence to recognize, discuss, and address the most common threats to web applications.
Learning objectives
Define the OWASP Top 10 2025 edition and its role as the industry-standard framework for identifying and prioritizing web application security risks.
Identify each of the 10 OWASP Top 10 vulnerability categories and describe common real-world examples of how they are exploited in breach scenarios.
Apply secure coding practices and configuration standards to prevent OWASP Top 10 vulnerabilities in web applications.
Analyze recent security breach headlines and map them to relevant OWASP Top 10 categories to identify patterns and emerging attack trends.
Evaluate how OWASP Top 10 risks change over time and assess the factors that drive certain vulnerabilities to rise, merge, or decline in industry relevance.
Communicate security risks and remediation priorities effectively to software developers, QA testers, and non-technical stakeholders.
Create a security integration plan that addresses OWASP Top 10 risks at each phase of the software development lifecycle, from requirements through operations.
Develop a role-specific action plan that makes OWASP Top 10 security practices actionable in daily development, testing, and operational activities.
