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. ;>

The only course (first two weeks only) in all the certification that was helpful, to polish my networks knowledge only, not for the security part. At the end this course is a summary of basic networking, and a "just buy some cool IBM products that do everything for you". The second part of databases is some random information about databases and obvious information of why you need to secure it.

A good course. I got to learn many new & informative things. But the video sound quality is too poor. The voices are muffled and you can't hear properly. Only a few videos are clear. You have to live on subtitles in order to understand what the instructors are saying.

Good to learn. Have many loopholes on the level of beginners as need more reading about every video. Although the candidate could not get more clear. Candidate clears the quiz but not too confident about the knowledge. Thank You

the course really give the brief understanding of network Security in computer network. Also what are the vulnerabilities in Database and how to prevent it. But the topic securing database is not so much interesting.

Good overall, some dodgy sound recordings, and some videos were abit lengthy in just raming IBM down your throat, but that's fine as atleast you're learning about their software and how SIEMS work..

very helpful context but the audio quality of an instructor is very bad there is no clear pronunciation of the words and no proper caption text is embedded with video.

The sound quality of most lectures is bad.

Some lectures seem chaotic/unstructured . In week three there are two videos of 8 minutes which contain only one slide,

Please work on improving the voice recording as it is quite difficult in some areas to understand what is being taught. Thank you so much.

I was expecting a more interactive course, one involving hands-on experience with the softwares, used ti teach the course.
