There were 2 major problems with this course:

1. Some of the presenters have such thick accents that it was difficult or impossible to understand them. This is a clear barrier to understanding and learning and should be fixed immediately; however, I notice from the comments of others that the complaint has been made for years and I therefore infer no one cares.

2. Some of the presenters delivered the info at a level higher than beginner. This is also a clear barrier to understanding and learning but I guess as long as people earn an overall passing grade, there must not be an actual problem. However, I suspect many others have done what I did and researched the topics on their own using other resources.

If these problems persist for the other courses, I will definitely non-recommend this course to my associates.

The information in this course is not bad, however I want to issue a complaint about the quality of the English transcriptions, which is far below the mark. It seems they are either computer-generated or made by someone with poor hearing and no understanding of the context and/or subject matter. Even a layman who has read the material as a whole, could do a better job. Some of the presenters also explain things using examples, without first explaining the issue in general terms, leaving the learner guessing as to which part of the example is or isn't relevant to the explanation. Some of the quiz questions do not refer to materials discussed in the lecture (example: a question about Vulernability Assessment Methodology in week 1 or 2, while it is explained in week 4!)

Honestly, I really enjoyed the content and thought the information they said while doing the presentations was great. The problem is IBM seem to be using the worst mic I have ever heard. Like you can see it was done in 2018 but they could afford to give the Lecturer a decent mic?? Unfortunate, else this would be a very good course, its just hard to understand what there actually saying. Even the subtitles don't know what they say sometimes...

Also to note, the quizes are really hard because it doesn't even say what I tried to answer. Disappointing, all the other courses I've done on Coursera at least let me see what I got right and wrong. And then video quality look 360p at times, terrible production quality.

I think the information being discussed and shared is great, the quality of the videos is not good at all though. The audio is different on every video and I you can barely see what's being displayed on the slides, even when I change to higher quality on the settings. I appreciate the industry leaders providing their insight but there's too many "umms" and not enough well spoken presenters. I don't mean to be harsh because I think the content is good but you can barely understand what they are saying. Perhaps someone who's confident & does presentations often should do them. I would even lower the volume on the videos and tried to read what they are saying at the bottom but even that barely makes sense.

Es un curso muy básico, te brinda conocimientos clave en muchos aspectos de la ciberseguridad, pero dan mucha vuelta a ciertas ideas o conceptos, hay cosas que es innecesario repetir y repetir el mismo concepto, el tiempo es algo que no regresa y me disgustó que lo ocupen en repetirte las mismas ideas, de hecho hay conferencias en las que te pueden decir la idea en un minuto y no dar vuelta a lo mismo en 14 minutos.

Otra situación que veo es que hay instructores que tienen fallas en su micrófono o en su conexión de internet y eso provoca que el audio sea pésimo porque se escucha mal y encima de eso tienen mala dicción entonces no se entiende lo que dicen y su discurso se hace incomprensible.

I think overall the way the course is offered is great. There were a few things that I found could use improvement. Audio is definitely something that could use an overhaul. The other thing is the way the information is conveyed. A lot of times the speaker was not only hard to understand, but the delivery made for a bit of confusion. It might help to write out what is going to be said rather than to wing it. Also, the word "So" is overused as well- some improvements in the English department would do a lot of good. Overall, you can certainly learn a basic understanding of Cybersecurity from this course. The convenience of fitting it into a busy life is the best thing about this.

I enjoyed the learning experience but a somewhat hard time understanding some of the content as it was being presented. I had to read the transcripts because either the video quality was horrible or the presentation of the lesson content using the the English language was very inaudible and extremely hard to understand. Some of the presentations should be quality checked for a more effective way of communicating when English is your second language. I found myself relying a lot on the transcripts in order to understand the words being spoken. It can be very distracting when trying comprehend the lessons.

It's alright as an introduction of the world of Cybersecurity. The selection of topics is neat, I just wish the execution was a lot better. The audio quality is really bad for most of the lectures, you'd expect that IBM would have the budget to give good mics to their instructors in 2018. Some of the slides are really bad depending on the instructor, the text is really squished together and for some reason they are plastered with comic sans as a font and silly stock images. Can't say I regret taking this course but I would say it's only for absolute beginners to the topic

This course is very informational and is user / beginner friendly in regards to navigation. An area that can use improvement is the audio and the transcript of the videos. Those 2 aspects are crucial to student learning as they contain the information needed to learn the topics covered. The audio is often impossble to decipher and the transcript is also unable to understand it. Lots of information I had to utilize outside sources to cover due to the course. Aside from that, great course! It was a review for me mostly and some new information learned as well. Thank you :)

Generally good content, but poor and unorganised delivery. The same is throughout other courses within this specialisation. Sometimes the topics are presented at very high level, and our of suddent the next video jumps really deep in details without enough prep or context, than again goes high level.

Some of the presenters are hard to understand because of accents or poor sound quality.

Overall, it is hard to piece the whole picture out of individual vides and courses in the specialisation together; as if the specialisation lacks a logical end to end syllabus.

The course materials were unevenly elaborated, some concepts were very well explained others were not. I would suggest that on topics involving novice audience, it is very important to properly articulate and teach as opposed to delivering lectures. Sometimes, when the audience is more advanced on a subject matter, lecture format would be very helpful. But this course is usually taken by individuals who don't know anything about computers or security. We cannot perceive lecture format about specialized cyber security events as well as professionals can.

kind of average course. Most of the instructors doesn't explain some of the vast topics as in a understandable manner. They seemed to be lazy while teaching and there were some disturbance sound in the background. Moreover, this part of the course mostly focuses on the rules and regulations kind of stuffs mostly related to US. there are students watching outside from US also. Overall the contents of this course is outstanding but as a student it is hard for us to understand hard topics with less explanations. I hope this to be improved.

Some of the Speakers on the courses, while knowledgeable, no disrespect to them or their skills - they should NOT be used to convey the information required throughout this course. It's a very technical and terminology-heavy course, yet you can barely comprehend what they're saying as english is definitely not even close to their first language. please replace 2 or 3 of the speakers with actual clearly audible speakers. Otherwise the course was great, interactive, holds your attention and generally enjoyable to work through.

The content is educational and offers a rudimentary base on which to develop Cyber Security skills. It is easy to understand and ideal for beginners and covers a large scope on the fundamental of Cyber Security.

One major drawback is the quality of the sound in which the videos are recorded. An example where this can severely hinder someone's education is if the student is a non-native English learner. There were sections where I had to switch on the captions in order to properly grasp what was being conveyed.

Overall an informative course BUT there are some serious issues. For example, the content was very repetitive at various points. Additionally, some of the video content is of very low quality (e.g. we cannot see the slide content well or we cannot listen to the speaker clearly). Some improvements will be necessary for the course to be of better value. Right now, it seems like someone took clips from different talks/presentations and tried to compile them into a course (sometimes not successfully..)

The instructors where knowledgeable and articulate, but the audio was terrible and sometimes impossible to understand. The primary reason I gave this course a 3 stars is because: 1. It's riddled with dropped vocabulary terms that are mentioned as important and then never talked about again. 2. The content is poorly written and poorly presented. 3. It's listed as a professional certificate and I couldn't find a single company that required it. Technically it's obsolete and a waste of your time.

The audio on the videos were poor and would go in an out as if the person was moving away and towards the mic. There were several videos that had background noises such as phone notifications and doors closing. Some of the speakers had strong accents that made it difficult to understand but the subtitles helped. Presentation skills need to be improved, speaking clearly, better slides, improve their skills on teaching, etc.

Overall, the content was very helpful and easy to understand.

When you hear of IBM, you think like Oh my God, this must be great since its of IBM but tbh, I was disappointed. Some lectures aren't well explained, some videos have audio error. As this is a beginner level course and the basic step to Cybersecurity, the course should have been explained in a detailed manner and easy way. Still 1,2 teachers were good. I didn't need to study some things after listening the videos. Thank you for making it possible for us to learn.

The quality of the videos and audio is quite low. Some questions in the review quizzes are advanced compared to the level you say it's required. I have an extensive background in networking and found some advanced terminology used (without proper explanation) along the course that would make a beginner level feel completely lost. I was able to absorb a lot of information that will guide me trough this "career change" path. I'm starting the second course. Thanks!

The course was really great for those who want to have an overview of the main topics in Cybersecurity. However, the audio wasn't good and, because the professors were, most of them, from different countries, it was really complicated to understand them, even if you are fluent in English. So, I was trying to read the subscription, but I missed the slides . If the subscription was inserted on the video, it would be more pleasant for the students. Congrats!

Did enjoy certain diagrams helped understand topics. But for a beginner the topics did not have layman definition of terms and helping build knowledge. Had to use google searches to explain topics better and professors at time assumed we knew topics ore systems before we even covered it. Hope rest of the course is done keep me motivated to gain the whole qualification. As I really want to learn new career path and make better future for my family.

There are many parts of the video where the speakers are not audible and the corresponding text is not helpful as well given it is a mere replication of the voice-text. This impedes actual understanding of the content. Moreover, while branded as a beginner course, the speakers used many different technical terms without explaining what they actually mean e.g. TCP, UDP, FTP etc. It's complicated for non-tech students to follow through.

Some of the disertations where it names the US (eledge) as one of the responsible of the creation of the Stuxnet virus assumes that it was part of the confabulation when in reality that has not been confirmed plus other implications to other nation states as responsbile for cyber attacks. The course left aside the legal frame of why being the US the country that receives most of the attacks it is unable to respond in accordance.

Some recommendations:

>> Improve the quality of the content in the slides

>> Make URLs referenced in slides available/clickable in the script text

>> Make unintelligible voice bits intelligible in the script text

>> Brief instructors to focus on insightful narration as opposed to reading from the slides

>> Ensure that quality of lectures is commensurate with the level of difficulty required to pass module tests / final exam

The content of this introductory course is great but the delivery is rather disappointing. Sound quality is often poor, as if the courses were extracted from a live webinar. Moreover, you can feel that some instructors are IBM professionals rather than teachers who are used to present content in a structured and intelligible way. Finally, the videos are slow to load and there are also regularly typos on the slides.
