This is probably the best IBM course at out the 4 main courses. Week 1 was amazing, clear, well produced and I could understand it a lot. I think the main reason being was that the lecturer could speak English clearly and properly and the mic was actually decent this time. Unfortunately, the rest of the videos, just the like other 3 course have TERRIBLE Audio. Most of the time I can't even understand what they saying (if the subtitles are incorrect), let alone the foreign accent doesn't help. Sure the material is alright but the production quality is shambolic. By the seems of it, it looks like its because all the video is being streamed with heavy noise canalisation so it just makes the mic sound AWFUL. Come on IBM, do better.

Having Ben Briggs (in weeks one and two) blindly read someone else's notes - with no interjections! - was extremely counter-productive. Fabian Alfaro (week 2) was also a poor presenter: student comprehension is minimal when one has to expend so much effort just to mentally translate into English what is being said in broken, unidiomatic, ungrammatical 'Spanglish' before attempting to assimilate the content being conveyed. The best part of this course was the fourth week: Dmitriy Beryoza is a wonderful instructor - lively, clear, thoughtful, and considerate of the student's attentiveness. Chris Winn (week 3) was okay, but the sound quality on his presentations was lousy.

Since this course is about to take about 14 hours of precious time, I felt responsible to write a review, to help others decide whether or not to take it. The syllabus for Week 1, 2 were fine, but not very informative. I found the subject in Week 4 perfectly informative, hats off to the instructor. What really turned me off was the content in week 3, which I suggest to be replaced with more helpful subjects. After all, many thanks to both IBM and Coursera for their endeavors and efforts, which have made it much easier for students to learn and expand their knowledge in almost every field.

Last part of the specialization was very interesting. Injection truly deserves more space on Coursera. Some of the contents were not organized properly and some of them were redundant or too basic but overall the experience was interesting. A little piece of advice is: give student more examples from the beginning as you did in the last past of the specialization because the first two courses were a bit too heavy and poor of a practical approach.

The course is excellent for beginners, even though it does not go that deep into the topic. It definitely does a good job of spreading out the basics and establishing the fundamentals of Network security and Database vulnerabilities.

I hope the audio quality will be improved and better captions will be made available. Overall, a pretty decent job. Thank you!

Other than the database monitoring module, which was just a sales pitch for IBM Guardium, the course provided quite a nice level of detail. It is a shame some of the presentation styles were not more focused on presenting, rather than just reading their content, but overall the course was worthwhile.

These 4 courses gave a lot of information. Thank you to IBM and the team for providing us the wonderful opportunity to learn something. But I would recommend that it could have been more useful if instead of slides they were more interactive and live demos. Thank you!!

É um pouco complicado compreender a abstração principalmente nas aulas explicando sobre Ataques de Injeção, então as vezes temos que procurar aulas e vídeos externos, mas é bom para se ter uma base de como funcionam.

As aulas sobre Segurança das Redes são ótimas.
