Great course. Fairly easy to understand, and although the videos are broken down into smaller files, they are definitely packed with information! Hopefully, I can remember it all and put it into good practice.

Well presented and understood, without any background in computer education it takes a lot from skilled lectures to let me understand the concepts and overall course.

Looking forward for next course.

Thanks

The course gave me a lot of in-depth knowledge about operating systems security that I didn't know very well. All lessons are professionally presented by IBM experts. Thank you so much IBM!

the overall sound quality was a bit hard to understand at some places but the information given and the way of teaching and the level of understanding all things were great.

This course is one of the worst. not sure what even was learned out of it, the basic operting sysem infomation was wrong at best. I have my MCSE and have developed world wide windows , Solaris , and Linux netowrks. the windows side was about hot keys, the linux had some very basic file information but incorrect about how shells processes data. and the Mac side ignored that its actully Unix with a preatty shell and forcused on really trivial information THAT does not line up with any security aspect out side of im a mac commercial. the speakers say things that lead me to understand that they do not. makes me wonder how many more classes i will take from this school and if I find its value worth paying for

Too basic, I mean learn Windows shortcuts is one of the videos, all the course its about basic terms almost anyone know, its no practical, I don't learn anything. I could teach this entire course, I skip the videos for weeks 3 and 4, and still got 100% on the tests.

this has to be the wort program and course I have ever taken thus far. All the video lessons are all AI no real instructors. the labs do not function properly, so you have to trouble shoot them to do basic things. I also don't understand why you can't copy and paste reading to notes most of the time when it's not iP, I have never seen that before. you need to fix your keyboard function in your labs it's not hard but it's hard to waste my time trying to fix them. the ai lessons have nothing but surface content thrown at you as fast as possible with no whys answered. I would say the absolute worst part is the final assignment which is not only buggy but insane you have to hope and wait on another student grading you. I found a great portion used the same photos, so they didn't even do it, not only that I graded people that were finished on January 9th its March 1st. The staff of IBM or Coursera or even advanced AI should be responsible for this it just shows how lazy the program is and thrown together with zero care. Some students I saw deleted their accounts because of the assignments were not graded. While I am sure Coursera and IBM still bill them even though they can't advance, if the student pictures are all fake fail them but do something. I expected way more from IBM but in truth it's the worst certification i have taken and is embarrassing, if I was with IBM I'd remove the name. I am actually afraid to add this cert to my resume I think I may lose jobs because of it. IBM and Coursera need to do better for paid learning courses, I feel bad for anyone taking this if it's their first cert. I sure wouldn't be back. Also, fix your known keyboard issues in the labs there's zero excuse for this and none of the other programs i have completed had this issue.

I do not recommend this course unless you are starting with 0 knowledge of computers and security, and even then, you can probably do better.

TL;DR - Very poor audio/video quality, inconsistent/incorrect information in several places, and a truly bizarre mix of ELI5 and unnecessarily in-depth information (even within the same videos).

The first half of the course is all about business process (ex. ITIL) and then rehashing the CIA triad and AAA (which was already covered in the preceding course in the specialization). This part is ok, though the business process piece felt out of place and disconnected.

The second half is the idiot's overview of operating systems mixed with some randomly in-depth information about file system formats and kernels. Ex. there's a video that explains what a file is (idiot's overview) and then goes into NTFS and FAT32 (randomly in-depth). If I don't know what 'file' and 'folder' mean, I sure as heck won't be able to figure out what file system format is suitable for a single-partition 128 GB drive!

The worst parts, though, are the poor audio/video quality and the inaccurate/conflicting information and quizzes. Many of the slides in the videos are so pixellated that they're completely illegible. There is missing, incomplete, or contradictory information. And, some of the information has become outdated, so even if it was accurate at the time, it's wrong now.

Really very disappointing. Let's talk about form and substance. For the form, we have the same big problems as in the introductory training: we hear badly, so automatic subtitles contain a lot of errors. What is new is that some slides are blurry and partially unreadable. Regarding the substance, we do not learn anything really interesting about cybersecurity. There are even videos on Windows keyboard shortcuts! As in the introduction, most of the speakers are not teachers. They get to confuse you on subjects that you know very well! Much talk is very vague, commercial, or only advertises IBM products. The tests simply repeat the content of the slides, often without understanding them.

Very unprofessional course. You're better off going on Youtube and watching a course of videos on the basics of Cybersecurity than this garbage. Someone with an actual good working mic, and doesn't ramble on or read off the slides is capable of teaching this better on the internet somewhere else for free than this.

This course is put together well. The quality should be much better, especially since there is a cost. Also customers should be clearly told that this are certificates, not certifications and there is a difference. Certificates won't help you gain employment.

I continued with the second course in hopes that the quality might improve. I was naive. The course material is repetative. The course sound quality has not improved. The same instructors with horrible sound quality were used for this course as well.

First week is mostly repetition of the previous course, then most of the other contents are only about bullshit terms, while the very few real content was on a very basic level.

Bien le bonjour à mes pairs, Je tiens à remercier chaleureusement les professeurs DeeDee Colette, Jeff Crume, Manish Kumar, Rav Ahuja, ainsi que toute l'équipe pédagogique d'IBM, pour les cours de la spécialisation "IBM Cybersecurity Analyst Certificate". Cette formation a été extrêmement enrichissante et m'a permis d'acquérir des connaissances solides et précieuses en matière de sécurité des actifs numériques, qui constituent une base réelle pour une carrière lumineuse dans le domaine. Je souhaite souligner la qualité des différents quiz notés et non-notés, les laboratoires pratiques, qui se sont révélés très utiles pour appliquer concrètement les notions apprises. Toutefois, je me permets de proposer une amélioration : introduire une nouvelle variation des questions et des réponses à chaque tentative. Cela rendrait l'exercice encore plus engageant et favoriserait une meilleure maîtrise des concepts. Enfin, je suggère l'ajout d'un cours de synthèse, un "Put it all together", qui permettrait de relier les différents concepts et outils enseignés. Une telle initiative offrirait une vision globale unifiée de la cybersécurité (ce que vous avez fait étant déjà assez exceptionnel) et surtout du poste en lui-même, ce qui serait particulièrement bénéfique pour les apprenants. Merci encore pour cette excellente formation et pour votre dévouement à transmettre des connaissances de grande valeur ! Valère Firmin KAMBO TAMBA
