Thank you for this course which was very interesting. It was very complete so there is a lot to understand and remember. The instructor explains very well and as my mother-tongue is not English, I understood him very well (thank you for the subtitles!). I am very happy that I've finished this IT Course and I would recommend it!

The only thing I am wondering is: what is done with my written answer? I've written texts for some quizzes and I was wondering if someone was reading them. It is just a curiosity!

Very intense course. I had a lot of learning of all the different types of security systems and getting to see how logs analysis worked for abnormal network usage, the different encryption protocols, most of the things here. It was nice to see how Security tied into sys admin with the use of LDAP or Active Directory, and that while complicated, it isn't all beyond my understanding and that there are literally youtube videos and internet articles to help explain everything. Thanks for a great course!

This was the most difficult and time-consuming of the 5 courses. I loved all of it except the final assignment, which I think had a poor grading structure and needed at the very least to have a better rubric for learners. The only way to complete it and earn full points was to either wing it and then redo it once you saw your peer grade or review the discussion forums to learn more about the assignment. It didn't really give a lot of room for creativity and the instructions were seriously vague.

This course has been inspiring to me! I have learned sooooooo much in my two months of high-tech training. GOOGLE/COURSERA, you have taken my mind to new, amazing heights that I've always dreamed of...THANK YOU ALL! From the creators to the researchers and everyone in between, you have my sincerest congratulations on all time, patience, training, skilled educators and knowledge to devise this unique program to heighten ones knowledge and dreams! Again, I thank you all!

Google IT Certification is one of the Greatest IT Certification which covered Hardware, Software, Networking, System Administration and etc, but I hope you will add iPhone and Android Phones in this IT Certification and I wish this IT certification will get the future soon amongst others

IT Certification as Microsoft, Comptia, Cisco, Linux, and others and I hope this Google IT Certification will be a requirement in soon and hopefully It will help in job search.

This happened to be the most interesting course of all (as far as I know). It did open my eyes into better understanding of some areas in IT security that I only had a little knowledge about prior to taking this course and also opened my eyes into much more new ones.

Its really been a very wonderful journey down the learning path. Thank you google for giving me the opportunity to be a better person in the realm of IT as a whole.

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.

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!

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.

I loved the whole experience beginning to end. I came in already having a BA from state university. Well organized, well produced, and combined with note-taking this course is a no-brainer. Go for it!

Great course for beginners and experts. Easy to understand and a good refresher for those who have been into IT for a long date. Recommend it to everyone looking for a high quality course on coursera.

Course was very knowledgeable and worth taking. I feel like the training wouldn't be complete if I didn't know about security and how important it is not just for me but for everyone using technology!

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.

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!!

The most wonderful course containing all concepts of IT security,defense in depth.Must recommendable cert for security professionals.Thank you !!

Excellent mode of imparting knowledge...you made me go after knowledge...in a quest for fulfilment!
