Very solid course. Quick overview about almost everything you need to know at the beginning. A lot of useful links with additional material to study. Thanks a lot for sharing the knowledge, indeed!

This course gave me great insights into the network security domain while explaining different types of DB vulnerabilities. A quick revision of my Cyber Security and Computer Networks subjects. ;>

some audio is difficult to understand, and it appears that the content is taken from a larger course (as we often cut into Part 3, Part 2, etc) without seeing the preceeding parts. Overall however, a good overview.

Weeks 1 and 2 (Network part) are nice

Week 3 is (Databases) is bad: speaker didatic and audio quality are regrettable

Week 4 (Injection) is the best: speaker has a great oratory and goes straight to the point

Course overall was very good - but thought the Guardium section felt like one giant advertisement. Could have showed off multiple tools or talked in general through the concepts. Otherwise, good course.

I think it was missing some more practical examples, not only on the IBM software. Overall a good course, good explanations and gives the basics.

Also, I think the sound quality cold have been better

A wonderful and nicely structured course for a beginner. Audio quality isn't matching the standard of other courses offered in coursera which should be improved in near future.

I enjoyed this course and also learn alot of things about cybersecurity and injection attacks.

many more are about the network and its security is to monitor and resolve by own.

Please try to make it more interacting like making sql injection statement by users them self and seeing how the output changes, it would be great if it was there.

In general the course was ok.

The network explanation and the injection part of the course was very good. A good explanation and presenters which spoke clearly.

Week 1 and 2 are pretty know if you have any network cert, but week 3 and 4 are a bit harder and The injection material was really good. Congratulations.

I thought the course information was good. I do think the transcriptions need a little work to reflect what is actually being said by the instructors.

Good in theory, but Better hands-on and practical experience would have been appreciated.

Instructors were real-world practitioners, loved them!

There were some problems with audio quality in the last week, and sometimes the teachers would ramble rather than getting to the point.

​En las practicas pueden colocar más preguntas para desarrollar más lo aprendido y poder tener más constancia al tomar el quiz final

I​ believe that the content within this module increases student understanding of potential attack vectors within a web page.
