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.

Some slides during the presentation were hard to read with small letters. Overall content is very comprehensive and well explained.

Some videos are not fully synced to the transcript and are not of good quality. The subject matter discussed is good though.

accents were sometimes challenging to dicipher; low resolution graphics of some diagrams meant some text could not be read

Very useful and necessary for starting in the path of Cyber Security but some videos had poor graphic and sound qualities

Had relevant and important information, and the instructors were much easier to understand than in the previous course.

Course was well structured however the poor audio recording and video rendering made it hard to follow to the dot.

I remebered so many thing than I study in Operating System, Cybersecurity and Cloud Computing during the universiry.

It was a good experience and now i am aware of how to secure data and managing a hardware

efficiently in a network.

the excitement into the trilling world of cybersecurity continue......I am enjoying every bit of this course.....

s been an interesting course, i learnt concepts about NFTS, FAT and virtualization aspects offered by RedHat.

Since I have completed introduction to cybersecurity course, some classes are very similar or exactly the same.
