OWASP Top 10 - 2021 Edition

What You Will Learn

• Identify the top 10 web application security risks according to the OWASP Top 10 - 2021 edition
• Understand the differences between the 2017 and 2021 lists, including changes in rankings and new categories
• Learn how to use the OWASP Top 10 as a guide to secure web applications

Key Concepts

The OWASP Top 10 is a community-developed list of the top 10 web application security risks. The 2021 edition includes new categories such as Insecure Design and Software and Data Integrity Failures. Broken Access Control is the number one risk in the 2021 list, which involves bypassing access controls and allowing unauthorized access to sensitive data. The Common Weakness Enumeration (CWE) is a community-developed list of software and hardware weakness types that is used to classify and describe vulnerabilities.

Code Examples

There are no specific code examples in the provided transcript. However, the transcript mentions various types of vulnerabilities and attacks, such as SQL injection and cross-site scripting, which can be used to illustrate the importance of secure coding practices.

Lesson Summary

In this lesson, we explored the OWASP Top 10 - 2021 edition, which lists the top 10 web application security risks. The list includes Broken Access Control, Cryptographic Failures, Injection, and Insecure Design, among others. We also discussed the Common Weakness Enumeration (CWE) and how it is used to classify and describe vulnerabilities. The OWASP Top 10 is an important resource for web application developers and security professionals, as it provides a guide to identifying and mitigating common security risks. By following the OWASP Top 10, developers can ensure that their web applications are secure and protected against common attacks. The 2021 edition of the list includes new categories and updated rankings, reflecting the changing landscape of web application security.

Practice Exercise

Review the OWASP Top 10 - 2021 edition and identify the top three security risks. Research each risk and describe a scenario in which it could occur. Then, brainstorm ways to mitigate each risk and prevent it from happening in a web application.

What Is Next

In the next lesson, we will explore the topic of secure coding practices and how to prevent common web application vulnerabilities. We will discuss topics such as input validation, authentication, and authorization, and provide examples of how to implement secure coding practices in real-world applications.
