Too many technical issues, for example AWS assignment cannot be mark as completed, some assignments cannot upload attachments. Instructors are not engaging in any reported issues in forum. When I contact the support, they ask me to contact AWS to resolve the AWS assignment issue, which is totally ridiculous.

It is the first subscription course I tried on coursera and it is the worst course I ever tried on coursera. Yes, all other free courses I tried are way better than this. Honestly don't get how is this poorly setup courses and assignments daring to charge fees. Totally blatant and ridiculous.

It was quite poor compared to other courses I have taken within Coursera. The lectures not very useful, the pictures quite messy, the instructions for the assignments were not clear, the screenshots didnt match the current status (mainly regarding AWS). The bright side is some of the lectures were interesting.

Instructor is very nice and educated about the concepts, but his English is so bad that you have to follow the transcript 50% of the time in order to even understand what's being said. While reading the transcript to decipher the speaker you miss all the slides/graphics.

I'm very interested in the content. But I'm unable to understand Prof. Chew.

Difficult to understand instructor

The course is excellent in terms of syllabus and objectives. IN my view, it would be even better if there were more explanations about the practical exercises

Lectures are fine, but the use of AWS instance is terrible and there is a few support .

I have completed so many courses with coursera and this one seems to be the worst one. The instructor doesn't even bother to reply in the discussion forums. The AWS credits are not given inspite of filling the form multiple times. This disallows us to complete the peer graded assignments and hence hinders the completion of the course.

It is very good to learn basic security for the computers and Networks. Up to week 4 I learn only computer security.

This is well organised course its a great assets to my profile.

Coursera's products and services are provided by Coursera

This course is awesome

Its to hard to understand the Professor and the assignments are kind of hard to accomplish 100% because some of the commands and shortcuts are outdated

The course could be better organized. From a security perspective, it should be accurate, not careless and cumbersome. But unfortunately, there are many mistakes within the organization of this course ranging from spelling mistakes to placing quizzes & assignments before a video that covers the subject. The arrangement with AWS is also haphazard. Instructions are not clear and specific. Much of my time are spent on understanding what exactly the objective of a certain assignment. It could be stated clearer and more specific. There is an assignment which requires 4 deliverables but only provide 3 file upload buttons. Overall, it is a bit disappointing, and I couldn't wait to finish the course.

Poor attention to detail. Confusing and ambiguous quiz/exam questions. External linked materials of superior quality to lectures; the instructor provides insufficient additional value to make the course worth the time and money. Better to find a high quality textbook and self study.

Really poorly delivered video tutorials. Spelling and grammar errors throughout. Not what I would expect from a university.

The assessment wasn’t a test of understanding, more a test of what a student could regurgitate of pointless facts from past scenarios.

I found it quite difficult to understand the professor's lectures, and even with subtitles turned on, I felt that a fair amount of the content was illegible due to the professor's improper grammar, incomplete sentences or thoughts, and extremely slow rate of speech. The practical exercises are interesting, when they work. However, I discovered several dead links in the recommended reading assignments and practical application instructions. Lastly, the exam for week one seemed remarkably impractical, as it contained questions about specific scenarios that did were not covered in the course material. Additionally, MANY questions contained extremely poor grammar or structure and quite frankly made little to no sense. I am a big fan of Coursera and purchased an annual subscription after enjoying a course in R and Python, and was very much looking forward to this course. If I were not beyond my 7-day trial period I would be requesting a full refund and continue with future courses on a per-course fee schedule.

Here are the issues I am having with this course:

- It's really hard to understand the teacher talking.

- Quiz interrupt often while the teacher talking.

- Most of the time the teacher seems just reading only what is written on the slides, so no added value to the slides so far.

Overall, at least for now, this course seems not good at all, hopefully it will improve over time on the next weeks...

I had big expectations from this specialization but due to no response, I have no option to drop it. the course is very good but aws requirement is big trouble in completion. I think the Instructor should find an alternative way that ensures learner/students practice and learn. I love the instructor and the course content. I wish the course will update soon and I will rejoin the course.

it was really hard to understand the instructor's speech.

PDFs for assignments are too long and distract from the main point.

Even I have send an email (it was asked in the assignment) to instructor, he did not replay to me.

This is a very intuitive and flexible course upon deadlines. The instructor has control over the course hence making understanding very simple

Excellent course on security, good teacher, good material and especially very good practical material.

Complicado si no tienes conocimientos mínimos de Linux pero muy satisfactorio por el reto

Very interesting and easy to learn, i loved this course.

It is good course! Professor is one of the best)
