Bottom Line

Solid video-based introduction to securing web applications, with some hands-on examples.

This Course Is Great For

  • Learning by Example
  • Expert-led Learning

In this course, Mike North covers seven common client-side and server-side vulnerabilities and security attacks that every developer should know, and how to mitigate them.

Throughout the course, North gives students a chance to look through a demo application and practice diagnosing and mitigating security vulnerabilities. This grounds the topics in real-world situations as well as gives students a chance to practice skills rather than just watching explanations and demos.

Before You Buy

One area the course doesn’t cover is best practices for storing secure data, like user data and passwords. For that, you’ll want to look into some courseware on basic encryption.

We're hoping Frontend Masters will update this course to cover JWTs, as they archived a course on JWTs as it doesn't meet their standards.
