Overview

Web applications are inherently insecure, as aptly illustrated by a pile of recent events. Insecurity is however not fundamental to the web platform. As a matter of fact, the modern web offers a variety of powerful security features that help stop a hacker. Unfortunately, not many developers have the knowledge and skills to leverage these security features to their full potential.

This course is imperative for understanding the fundamental security principles of the web. The course provides an overview of the most common attacks, and illustrates fundamental countermeasures that every web application should implement. In essence, this course offers you the knowledge and skills to build better and more secure applications.

This MOOC will introduce you to the web security landscape. Throughout the course, you will gain insights into the threats that modern web applications face. You’ll build an understanding of common attacks and their countermeasures; not only in theory, but also in practice. You’ll be provided with an overview of current best practices to secure web applications

Although no previous security knowledge is necessary to join this course, it will help to be familiar with the basic concepts behind web applications, including HTTP, HTML, and JavaScript.

TL;DR: Overall, I strongly recommend this course to web application developers and their ops/security partners. The course doesn't simply present a bunch of major weaknesses in web apps and then throw up its hands, but rather presents each vector in detail and shows you how to mitigate or eliminate the problem. This includes discussing the relative merits of different mitigation strategies, and raising awareness of the consequences to users.

An absolutely challenging course. It is longer that it seems at the beginning because you have to deep into the related material and the links provided in the extended information to fully understand the concepts. The labs are well planned and help to further understanding. The questions are more difficult than other courses in edX because you have to think and understand the concepts rather than memorize the theory. Finally, the profesor is an especialist and passionate of his job and transmits this passion and knowledge to the students. This course is a "must do" to every web developer and also for system administrators.

This is one of the highest quality courses I'm taking on edX both teaching-wise as well as excellent video, sound, and slide quality. Even though not all of the material might be news for web developers, I gained valuable insights and it also motivated and gave me the right tools and starting points to dive deeper into certain topics. The interviews with industry pros were a great addition.

I don't know about the other reviewers, but this course was very different than I expected. It went too fast and was too hard!

This course covers a lot of areas related to web security and guides step by step the common mistakes and ramifications in securing web application. A well-organized lab for many of the sessions helps in understanding the issues practically.

It also provides a good overview of the latest changes in the ecosystem to make applications more secure. It's a must do for all the developers who are interested in building secure applications.

The course lectures are concise and well prepared. Especially enjoyed the lab sessions giving hands-on experience with different security concepts, as well as guest interviews. The tests are not easy and composed in a way that promotes deeper understanding of the material. Great professionally crafted course!

Very challenging (for me at least) but it was an excellent course. I was never taught a lot of this stuff in school (either for Undergrad or Master's) so I'm glad I took this course. I think it contains a lot of essential information for web developers. I highly recommend it.

Simply excellent!!!. In my opinion, this is one of the best MOCs I have ever studied. Maybe, some of the tests were a bit tricky on some occasions. Honestly, I had not much time free, however, it was so interesting that I had not any doubt to go ahead and finish it.

The course is really useful for everyone who develops web applications. Only with video classes one can easily forget the true nature of a security breach, but this course comes with the pratical labs that consolidate the learning.

A must do. A high quality course completed with very challenging questions and exams. They forces you to reflect, study and deeply grasp the material. Topics, data and materials are really recent and up to date.

I spent lots of time and energies on this course, but the lessons were not clear, and I couldn't follow anything. My effort was there, but this just was poorly designed!

This course is really exciting. I have rarely followed a MOOC as well.

Internet Security is a much larger area than I thought.
