Great course that is full of useful information and presented in an easy to understand way. It's an awesome beginner course that will add to your knowledge and further your knowledge of IT security.
An absolutely engaging and challenging feat that I am so proud to have completed. I hope this opens new door and better job opportunities so that I can better enhance my future. Thank you Google :)

I enjoyed the course. I really wanted to take more quizzes along the way and less supplemental readings (instead I would prefer it be covered in some way). Overall, I learned quite a bit in this course. I was hesitant to jump into some things I had not done in the past, but it encouraged me to do extra reading, alternative practice, and even look at the path I want to thank. I am grateful for this course.

I learned TONS in this class and all the classes offered. I am totally grateful to Google and Coursera for making it possible, and I want to extend gratitude and thanks to the instructors who taught us and their support staff(s) who did the invisible behind-the-scenes work that the students never saw. I had a great time working with my student colleagues, especially those who finished with me.

this was a tough and difficult course for me as a beginner with no experience and very little background but with the well to learn and the drive as well as the videos of inspiration by google employees i push through and completed a milestone in my life and career as well.
GREAT PROGRAM EVERYONE THAT IS INTO IT WORK< CAREER OR WANTING TO JUST LEARN SHOULD TAKE THIS ENTIRE COURSE ON COURSERA

This was the true test of everything we learned. When it came time to do the final assignment I thought back and realized WOW, we covered a LOT of stuff! Network security is so important and I feel confident that I have learned pretty much all there is to know thus far in terms of what's out there on the market. Now it's just time to apply said knowledge so that I don't forget all about it.

IT Security: Defense against the digital dark arts, fully deserves five stars. The subject is huge and our lecturer ensured we thoroughly covered the topic with examples of the good and the bad including how cryptography works! The final assessment was worthy of the course material and demonstrates the immense amount of thought and care that went into preparing the material. Thank you!

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
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.

Hats off to Google's fun+mental team for "deep diving" into rock solid 6 weeks of IT Security:
Defense against the digital dark arts

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!
por Vera N G•
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!
por Jody S D•
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.
por Penny J B•
This was by far the hardest module to finish, but I did it and I especially would like to thank Coursera's support people for that. They rooted me on, and kept telling me not to give up. Thanks!
por Gourav D•
Great course a lot to learn and a lot to know along with great and cool teaching staff I enjoyed much and learned a lot. Thanks to all the teaching staff and google for such a wonderful course.
por Arbind L M•
It's very nice even the teacher is very pleasant the way of representing things is just mind-blowing i am too happy to learn with it. I feel I am too lucky to have such a teacher!! Hats off!!

Exhausting but worth it !!
por Sarah H•
too much info (too much terms that is explained) but not enough practice.
por Mikhail M•
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.
por Hans T•
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?
por Anthony D•
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.
por Naman K N•
I was lost while studying this course many times. Often the critical concepts were just spoken, at least have a PPT of critical concepts
por JITENDRA P•
I have submitted my verification still lot of delay in my certificate , it's really very frustrating
Much too dense to absorb, and not necessary for an *entry-level* IT position.
