(

quizzes) were useful for 1st attempts, but did not change on subsequent attempts. At least a few versions of the quizzes for each lesson would be helpful.

This is a good introduction to cyber security; basically, the topics covered include descriptions of previous attacks, types of threats, types of firewalls, and cryptography.

For an introduction course, I learn a lot more about network security and encryption. I would like to see some labs regarding security a network and virus detection methods.

COURSERA IS ONE OF THE BEST LEARNING PLATFORM IN THE WORLD, I REALLY FOUND ALL MY VIDEOS INTRESTING AND EDUCATING, BUT THEIR IS NEED FOR MORE CLEARER VIDEOS IN SOME AREAS.

It's thoroughly enlightening, I really enjoyed the whole course. It can be finished in a week, if you have available time. But audio and subtitle problems should be fixed.

overall a good introduction to cybersecurity tools and cyber attacks. Some videos needs to be redone for clarity; the speaker sometimes isn't understandable when speaking.

The content inside this course is useful for a beginner and the explanation is very good. The quizzes are far more beneficial to revise the topics learned in the journey.

The course was very good and informative. By only concern was that the instructors were not English speakers, so sometimes, it got difficult to understand their language.

The course was interesting and it would even be better if the audio quality can be improved a little bit .Learnt a lot about cyber security schemes ,programs,history etc.

This course is really helpful and informative. It is taught by people who have maximum experience in this topic. If would be much better if we get a pdf of the slides...

The Course is good however not for me. I am now unable to unenroll from the course so i cannot give this or any other course a good full rating if persons cant unenroll

Need to have basic knowledge about IT and technical word. The voice record system is not good in some video. Anyway overall knowledge is really good hope every enjoy!!!

Th course is very informative but the voice quality of many videos is very poor. i couldn't understand the words without subtitles which is a drawback for this course.

Very good introduction BUT, sometimes the sound is badly taped, the material is not equal in between the different teachers and the tone of certain teachers is boring.

Very informative, clear cut and explained in a digestible way but i will say some of the audio quality in the classes of, "Week 3" and Week 4" could have been better.

It is a good introduction and the speakers are very knowledgable but I think that the format of the presentations is not very engaging and the audio is always awful.

The narrators can sometimes give me headache 'cause the voice recording's quality is very poor.. But overall, it's been knowledgeable and thorough resource. Thanks!!

Good explanation with up to date examples and links for further readings. However some recording are hard to comprehend due to the sound quality not being too great.

I wish here was more on OS. I am not sure how much of OS knowledge we would need in the field. I will take an OS course to get a good handle of the subject matter.

There was only one problem with the entire course, the audio had very poor quality.

On the other hand the course was very well built, lots of good content.

Thank you

This course is indeed an introduction to the cyber world. It gives a firm theory-based grasp to the learner along with some basic practical ways of implementation,

It was a good choice to opt this course as it has provided me with exact knowledge which I was looking for,

The lectures are very simple and easily understandable.

A good introduction, but it didn't seem like all the information was useful, and I didn't learn as much as I thought I would. However, it is a good enough course.

Very compact course material , so a beginer can get a glimpse of the current cyber attacks and key concepts of avoiding and analyzing the attacks are understood.

Good overview class; excellent for beginners. Video quality a little choppy at times. Second week's workload seemed unbalanced to the other week's requirements.
