No organization—no matter how large or small—is invulnerable to security breaches. What makes all of these systems, and the software that runs them, susceptible to attack? 

The Open Web Application Security Project (OWASP) was formed to provide the public with the resources to understand key risks and improve software security. And every few years, they publish a list of the ten biggest application security vulnerabilities. In this course, application security expert Caroline Wong provides an overview of the 2021 OWASP Top 10, presenting information about each vulnerability category, its prevalence, and its impact. Though aimed at IT security professionals and developers, anyone who uses web applications will benefit from an understanding of these risks.
