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!

This course had some REALLY bad presenters, and others who were EXCEPTIONALLY good. The problem with the incompetent ones is usually that their bad grammar, syntax, AND pronunciation (!!!) detracts from their capacity to convey their knowledge, so the listener/student spends far too much time just trying to answer figure out "What the hell is he trying to say!?" rather than absorbing the meaning of and context for the information being presented. In short, the presenters who totally wasted my time were: Elio Echeverria, Ken Gonzalez, Warren Araya, and John McLaughlin - all of whom engaged in countless unnecessary repetitions and non sequiturs, and whose subtitles were a pale reflection of what they actually said. Thankfully, Joe Speno, Jude Lancaster, and Adam Seibel were excellent communicators, and their videos WERE a pleasure to listen to. On balance, the good presenters' efforts were overshadowed by those of their incompetent colleagues. The lesson you should take away from this? A SUBJECT EXPERT IS NOT NECESSARILY A GOOD EDUCATOR!

I had a constant feeling that a wasn't getting all the introduction i needed (i always felt that a could not explain what a learned it to someone else) so I paused this course lots times to complete my understandings by reading and watching extra free content outside Coursera, that sometimes were better than this paid course.

I still recommend it because there's a structure to follow and i helps in a first approach.

Even with a 3/5 experience in the course 2 i'm looking forward to start the course 3, for i clearly need some suggested organization to learn about Cybersecurity.

I found this course to have too many quiz errors and audio troubles. You can get through them but it does require going back and retaking a quiz or two until you figure out what the correct "wrong answer" is. I would suggest that IBM or Coursera go back through and at least fix the video transcripts where the words show up as [inaudible]. Other than that there is good information provided. The first two weeks cover a few topics presented in the first course (with the exact same videos) which I found strange. Week 3 gets into good stuff that is new.

Some of the material overlaps with the previous course. Videos can be a bit rambling, and quizzes could be improved by using clarifying language and de-emphasizing trivia questions. The material on Linux and Windows is a good intro to how the operating systems, but not especially meaty on security measures. The cloud modules suffer from the same -- they introduce basic concepts but do not cover what you can do to secure VMs. OSX doesn't even get a video. Most useful in terms of getting the hang of manager-level language about security.

Goes over relatively basic information. Seems to repeat itself from other courses and uses the same videos. Visual quality of the recordings are questionable at times and not legible. Tries to cover in-depth information, but then will side step for a half hour to teach you about commonly known keyboard shortcuts.

Most of the quizzes have questions which are unclear and doubtful .

Few questions are out of the course material which are very confusing and no proper details related to questions are available on the internet as well.

The questions aren't reviewed properly with no system to check on the wrong answered questions

This course had the same drawbacks form the previous one in relation to sound and the transcript. Also, when covering the material related to Linux and Unix, it may be benefiial to take more time to describe and impliment some practice exercises with using commands. For better familiarity. Overall good!

Not gonna lie, this course is really boring. Most of the time you will be asked to remember corporate lingo and week 4 sounds like a commercial for IBM's cloud services.The only redeeming part is week 3, which is a decent intro to operating systems. (But they're not kidding when they say "basics")

I expected to find about how security is achieved/can be found in each operating system. However, for window and linux the lesson is about the operating system basic! Ex: Window shortcuts and basic commands have nothing to do with the security aspect as far as I am concerned.

Good information, I enjoyed the course, but really does not provide as much information as the title would suggest. "Operating System Security" didn't really dive much into Windows or Linux, but just gave a very basic overview of the operating systems themselves.

Terrible video quality, on the moments not even readable at all. Audio quality also terrible, but a bit better than video.

A lot of outdated links, references etc. Also, issues with grade system.

Some of the video presentations lacked quality of video, and the data displayed were blurred and illegible. Did not expect that from courses being offered from an esteemed organisation like IBM

I thought there was more practical course. and because I already knew most of things, but I didn't have any courses in cybersecurity. So it's more like to high school students dedicated.

English transcription is not accurate which makes it difficult to understand content especially of those with heavy accents. Content presentation is not user friendly and also boring.

Video quality is low and the reading assignments seem to require an already existing knowledge of Cyber Security. It's a solid course but i'll be honest im lost a lot of of the time.

The information is vast and easy to follow but the video quality is not the best even at the highest setting making it difficult to understand the illustrations in the videos.

Content is great but a lot of the graphics were unreadable due to color combinations, size, or being out of focus. Sometimes they even covered up useful text on the slides.

Audio volume was low for a lot of the instructors, Several of the reference links returned with a 404 error. Overall it was a good course with a ton of information.

While the information was good, may of the images used in the video lectures were blurred, so I had to use other resources to get through the quiz questions.

Some materials do not show correctly in the video.

Some translation texts are incorrect or typo.

Content was less relevant for me too but overall was OK.

This is just a basic intro for everything they mentioned . video and audio quality should be improved a lot and the explanation I would say it's okay .
