i learned a bunch in this course. the intrusion detection and prevention and packet snooping is something i have been interested in for some time. i have utilized a few linux servers of the years and have never implimented any of the things i learned here.... you can be sure i will now. I just wish it was more in depth, however for the scope of the course this was still a great lesson

Dear Google & Coursera

This was the most profound course for me, I was able to learn more in-depth about IT security. In fact this course made me want to pursue a masters in Cyber Security. Thanks you Google and Coursera, for making this possible for people like myself who has a passion for IT but live outside of the united States of America.

Thank you

The final project was/is a precursor to submitting a document for job assignment or contract. The information learned was useful and encouraged growth. I spent more than reading the supplementals than normal. I am better equip for a job interview in IT Support and Software Security Engineer, which was a goal. Thank you for this course, content and interactions.

Definitely, this is the good challenge, I really enjoy "Google IT Support Professional Certificate", was a good experience, It helped me to remember some topics and to reinforce knowledge in IT.

It is important to stay in constant training, practice and read and deepen in this field of information technologies. Is an advice of an IT person.

An exceptional course with great insight and explanation on every single concepts. Helps students to understand the roots of security, slowly teaching them about its use-cases and applications in real life. Would recommend to anyone who has keen desire to understand security basics and have an overall idea about this subject.

Great work preparing the course!!

Very challenging but rewarding course to understand info sec and cryptology from scratch. While the content could go really (over) technical, but the course is full of good topics and addressing different key themes to make you think and research more. The quiz, lab and coursework was very difficult yet intuitive and engaging. Great course, learnt so much!

The course was excellent and complete and I had to study a lot and work hard to accomplish it. The teacher explained very well and the practical tests and quizzes are very well prepared. I must say that after working with IT so many years, there were lots of new and very important subjects that I learned. Congratulations! Thank you very much!

This course had its challenges. Going through each course there were things I already had a basic understanding and some was new to me. Coursera had its lessons and courses well thought out. Its instructors were knowledgeable and gave me knowledge and skills that companies are looking for. Thanks for this well designed certifications.

Exhausting but worth it !!

the concepts and terminology covered in this course could be explained in a simpler better way. I found some websites and youtube videos which explains these concepts in a simpler but more effective ways. Like all other courses in this certificate program, some materials needs to be updated. looks like they have been neglected for 3 years and it is a really long time in IT industry.

I was really disappointed by Google since I was expecting a much better job from them. It is clear that they didn't assign enough time and resources for this certificate program .

Lastly, I would like to thank all my teachers . You guys are awesome and very enthusiastic about teaching and motivating learners. You guys can do only so much with the limited time and resources you were given. Best of luck and God's blessings in your life journey.

Thank you again.

I enjoyed "The Bits and Bytes of Computer Networking" as much as I am disappointed in "IT Security" course.

1. The instructor usually does not bother to provide explanatory images or diagrams. He just talks and expects us to build the full image in the head. He uses many abbreviations, some of which were not introduced before. Hm, what do you have the video for? For instance, Kerberos protocol. The diagram (wow, they have one) includes "KDC". It is never explained what it is. The helpful diagram is hidden while the instructor talks about what happens in the protocol. C'mon, do you really think that your face is more important than the diagram in this case?

2. The information is very high-level and I just can't see how it might form a proper structure. "Digital signature is used to proof authenticity". Ok. I new that. If anyone does not know that, they can easily guess from its name. How exactly does it do this? How exactly is the private key applied to form a signature? The answer is actually simple: append a digest formed as a message hash encrypted with a private key. But this is not in the video.

3a. Some information is plain wrong! E.g. "But the output should be unique to the input, such that two different inputs should never yield the same output". This is theoretically not possible, since the size of a hash is fixed, while the size of a message is arbitrary.

3b. Another example: Diffie–Hellman. The instructor says "combine the numbers" and the image shows "+" sign. You might think this is addition. But it is not. It would make no sense to use addition here. The algorithm actually uses power by module operation, but it is omitted from the course.

On the whole, great foundation. But the number of quizzes vastly outnumber the labs - decidedly not "hands on" - and the labs present held my hand the whole way. The technical detail is sparse and the quizzes were confusingly worded. I loved the certificate on the whole, but the last two courses were significantly less engaging than the ones before them.

Missing transciprts, spelling mistakes in transcripts, lots of missing supplemental readings. What is the point of offering a course when no one checks the basics are right?

Lots of talking and almost no hands on that explains how to explement or how to actually use the knowledge and practices they talk about.

I was lost while studying this course many times. Often the critical concepts were just spoken, at least have a PPT of critical concepts

This is Ahmad Serag, an Egyptian student studying high school in Saudi Arabia.

My course for Google IT Support Professional Certificate from Coursera I've finished today after I stayed up nights and wrote and documented a lot of things and meanings to this wonderful course about the IT field from Googlers, It's been an incredible journey. These are all not easy concepts for a 17 years old guy with unlimited passions, but I made it through the whole thing.

So, I’m asking google today if you can encourage me via giving me a T-Shirt from google as a congratulations gift on finishing the Google IT Support Professional Certificate that will support me to apply for an internship at google in future and go forward for my goals. Hope Google team celebrate me :))

Warm regards,

Ahmed Serag
