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. ;>

This course is a good example that big names doesn't mean big quality.

I took this course from IBM expecting to see some highly skilled tutors & high quality teaching methods, but what I found were just power points presentation and voice quality that is so bad that you wouldn't understand a thing without the captions. which is a real shame cause the materials were actually good and useful.

It is a mix of webinars that have been cut and poorly edited to create a course. There is a part showing an IBM tool in a pre sales way instead of teaching the concepts.
