The presentation graphic is not so good, it is very unclear on some parts. Learning material is not that difficult to understand, well done. Tests, to me, are somewhat easy and needs to be more challenging.

Amazing course: best beginner course to get complete overview of Roles and process in cyber security world and this course provides good knowledge of different types of operating systems and their security.

The course was generally excellent. There are some issues with the quality of various slides, and the accuracy of transcripts. Also, some quizzes contain bugs that can create confusion and frustration.

I enjoyed the course and learn valuable information but I would have liked a little more hands on interaction such as interactive drag and drops, setting up a virtual machine or securing one.

I have nothing but good things to say about my experience with Coursera. I have loved the learning I have been able to do and look forward to taking many more classes with them 

There is no practical part . T choose this topic , i think it consists practical parT but i am disappointed.

but thanks i got different other conceepts.

THANKS TO IBM TEAM.

Buen curso , aplicable a situaciones de la vida real en los temas de cloud y Ciberseguridad , instructores siempre yendo al grano ,todos los temas bien explicados .

i would give it a 5 out of 5 but one aspect i didnt like was that some of the images were hard to see or appeared very blurry besides that this was a good course.

Extremely informative, however I just wish there was more hands-on learning rather than just watching videos. Nonetheless, it is still a great course worth taking.

Very Concise The lecture doesn't bombard you with unnecessary jargons. Learned a lot about Roles and Process although the Windows/Linux part is kinda introductory

Good, but need to improve on the details.

I did a lot of search to underestand all the comcepts.

The general idea is there, but miss the point on explanation.

Learned a ton! The only suggestion would be to improving the quality of the content such as video graphics which was not up to the par at all. Thanks, IBM!

The course was great. Unfortunately some of the quizzes were not that obvious which created quite some confusions and frustrations in the learning process.

The course was very helpful for me as I was provided with the roles available in cybersecurity domain and what precautions are taken to keep system safe.

Falta download de PDFs (se possível traduzidos) e dublagem em várias línguas.

Tirando isso, excelente curso. Parabéns equipes Coursera e IBM! Obrigado!

very informative, all the technical details of cyber securities, hacking, operating system loopholes everything covered in detail, absolutely loved it

Good summary level course. Some overlap with the Intro Cybersecurity course. The operating system component is high-level and not too technical.

it was a good course but there is one issue that i faced is that the in some quizzes i was answering correctly but it is showing my answer wrong.

Monitoring by staff of the discussion board would be helpful as many students run across similar issues during the duration of the courses.

Good course, good material and good teachers, however I recommend improving the presentations, the sound and the diction of the instructors

Need to improve video quallity and also improve quality of pictures in slide because it is very difficult to read becausee of low quality.

Interesting topic which evolves rapidly. Some of the videos are in really bad quality with unreadable content in the screen or bad sound.

Interesting and lots of new stuff but not as demanding as usual. Excellent overview though. I can recommend this course for any beginner.

Some videos are of very poor quality and in many video lectures, there are some inaudible parts that covers some important topics/name.

A good course to refresh your memory regarding Operating Systems but also includes new knowledge about topics like Cloud Computing.
