Good content though the transcripts need editing - I suspect it was passed through a speech recognition engine. The final assignment had two glaring errors in the marking rubric, so overall good content but the text needs attention to detail.

I learnt a lot of new concepts and technical knowledge, far beyond what I already know while working as a Systems Engineer doing tech maintenance! Nicely paced and throughly explained. Looking forward to taking more courses from Coursera!

the labs need some refining on copy and paste options, the qwiklabs help was the most difficult part of the course, other than that I really enjoyed the course and training, and the ability to learn anytime 24 hours a day.

This course is very complete, however, I think it could be better if the lectures include more knowledge about samples about good practices especially for IT plans, and include more block diagrams or graphics of solutions.

What was with that final assignment? This is a 50-person company making widgets, not something serving as a contractor to the DOD. So many of the things being looked for are complete overkill for that sort of environment.

I have learned a ton but I would have loved to have more labs that were in addition to the guided ones to test application knowledge in real time. Thank you to all of my instructors I am truly blessed by your knowledge.

You get a good understanding of what a virus or malware is, and what it can do to an unsupervised computer or network. You don't want ransomware on your system, or lose or corrupt any file you need in your organization.

Quite informative, though the practice and lab are a bit shallow. Peer-graded assignment is VERY annoying when you complete the course on your own pace (No one has submitted anything for you to grade or to grade you)

Excellent course. I highly recommend this course for anyone just starting out in the IT Security field. This course provide excellent overviews and foundations for anyone just starting out in the IT Security field.

Good learning practice and straight to the point, I'm learning a lot every video and course, this is what i was looking for as new to the IT field. well done Google and who ever behind this Innovative approach.

This course is great with helping anyone that may want to get a foot into I.T. this will teach you the fundamentals and more. I would definitely start here if you don't know where to begin to learn about I.T.

Very Informative Even though a lot of big words and abbreviations were thrown around which needed us to research and learn about the words and topics before returning and continuing on the main course.

It is a amazing amount of knowledge I've got from you. It was a very pleasant way of learning. Give the students a small e-book is with all the syllabus and you'll get the five stars. Thank you all!

Personally, I found this course more dense than the previous courses. I would have liked to have seen more visual descriptions of the topics, e.g. cryptography. But other than that, great course :)

2020年12月19日

This course was too good . there were few topics which some more elaboration. such as tacas+ , SSH etc.

Otherwise it is a very good courses to have basics cleared . topics covered are perfect

I feel like this went way more in depth than I think most people just getting into it can handle. I think either this needs to be dumbed down or drawn out a bit more, but a lot of great info.

2019年8月22日

A more in-depth concept can be included in the course and provide a reference to open source tools/technologies so young and aspiring security professionals can gain more out of this course.

This one was ok. A bit difficult to deep dive into security concepts. You hear about them all the time but never really knew how they worked exactly. I take security more seriously now,

2020年4月23日

Really very good course.

It teaches so many things which we have facing in our digital life but didn't noticed.

After completing this course I'm conscious now about security and attacks.

Very complex information, liked learning IT. There were times when I wished I could ask instructor a question or explain something further. Thats the disadvantage of online, I guess.

2020年6月20日

Very good, but personally, I would have preferred visual mode of instruction, which includes but not limited to a blackboard rather than a person sitting and telling us the concepts.

2019年8月25日

I'm personally not a fan of cybersecurity as I find it boring and complicated. However, the teacher did a phenomenal job of explaining things and I genuinely enjoyed learning!

I have to admit that the material was pretty heavy but the instruction and the structure of the lectures were amazing! Probably the best course of the series! Excellent job!
