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!

I really like the course being split up into short video clips of not more than 10min. The transcripts provided are really helpful too. There are some areas of improvement:
1. Sound quality needs improving - while the sound quality is good in most of the videos, videos of the whole topic on Data Source Types are not good at all. The transcripts is not quite correct (perhaps due to the unclear sound recording) , which cannot deliver the content of the topic as clearly.
2. "Key Take Away" - this is very important for all topics as it summarises the key points of the topic. I really like the "key take aways" mentioned in the Deep Dive. Hope this can be added to other topics too.
I found all topics covered under Network Security and Deep Dive are very clear and professionally produced. The Data Source Types on the other hand is not as proffessionally done as others.
Thank you for taking the time to read my feedback. :)

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.

I give it three stars because it's an exception to the high quality of the previous modules. The quality of the audio is away far from reasonable. And I had to activate the subtitles because I couldn't understand what the person was saying. And seems that this person was forced to give this module.

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,

A good amount of knowledge, but need to improve audio quality as sometimes it's difficult to understand what the instructor is trying to explain.

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.

A lot of this sounds like it was literally phoned in. Mostly good material, but it's definitely overdue for a major revision.
