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 sound quality of most lectures is bad. Some lectures seem chaotic/unstructured and not very well prepared. In week three there are two videos of 8 minutes which contain only one slide, which could have been divided into more slides. Some slides have a too small script. One video seems just like an advertisement for one of IBM's software products. Although the instructors are experts in their respective field, they do not seem to have much expertise in giving lectures.

The content is basic overview of network security. I would say that the lecture videos of the first 2 weeks were just 'okay'. But the practice quizes made the content easily understandable.

There's a lot of good information in this course and I did learn a lot, however the presentation is very, very poor. The info in this course deserves a 4 star review, but the audio is absolutely terrible. Also some of the videos have extreme;y poor visuals. This course actually makes IBM look like a company with no quality assurance department.

All chapters are of poor technical quality. Especial the audio quality in close to inaceptable. Some chapters are also of badly presented content. Only two are at least informative. Some refernces are not technically not usable

I have found this course very useful to understand fundamental of Network Security. Information on Database Vulnerabilities ellobarated very effectively. This course will definatly very useful not only for IT Security developer, but also for application developer who wants to undertand how network security works and how to prevent database vulnerabilities. For additional information, Both topics are mutually exclusive and in course also there is no reference of first two weeks content in next 2 week content or vice-versa. Thanks a lot.

the Cybersecurity Fundamentals series course is good for the basic level only.

We need IBM to create a more advance level course in the near future.

It was a little difficult to recognize the main point in "A Data Protection Solution Example, IBM Security Gaudium " section. Will be good if you do small refactoring. Dmitriy Beryoza, thank you for the great session.

This section leaves a little to be desired, as the instructors on a few videos are difficult to understand due to poor recordings. Some of the subject matter presented is gone over too quickly to actually help the student understand.

The Course was very challenging and the same trends were observed here: Cyber professionals should understand that their student audiences have absolutely no knowledge about computers let alone cyber security. When they understand that, they would explain the key concepts more efficiently. For example, when discussing DHCP, the instructors assume the audience is just refreshing knowledge but that is not the case. The discussions on SQL Injections were also directed at audiences who were wondering on professional wisdom on cyber security practices. But this issue is present in almost all cyber related topics across companies. Please assume the students have no idea about cyber or security or cyber security. Most people hardly even know the difference between Windows and Microsoft Office.

The course was great I very much enjoyed it. The only problem was that in week 3 it was more demo than written side material to support the question that was asked. I had to go back and review every transcription to find supporting answers. All in all, I learn a lot more regard SIEM configuration.

Very well educated instuctors and coursera will help me complete my professional certificate and set me on a new path to my new career in CyberSecurity, I have learned so much.. Im a go getter and when the NY DOL put this up for their people I was so astounded because I love to learn. And I will continue to learn throuhout my life in this field as it always new information gets taught and the hackers come up with some other schems , I believe in security and I believe in myself . I will succeed and have the job I always dreamed of and will take care of my family. But coursera I will continue to always learn as my brain always need to absorb new knowledge and stay healthy. Thank You coursera.

With the exception of week 3 this is by far the most valuable course of its curriculum, and has the best quality materials. The third week, unfortunately, suffers from the same issues as the rest of the curriculum - poor quality of audio and slides, and having you sit through glorified infomercials for IBM security products. But weeks 1,2, and 4 are an excellent introduction to network security and injection vulnerabilities, and earn the 5 stars on their own.
