I have learned enough the cryptology, hashing idea, AAA Security, and etc. in a word IT defense against the digital dark arts enriches me with security knowledge a lot.

Very interesting course. Even though seems like just scratching the surface some of the basic concepts introduced stretched my brain! Well explained and guided though.

Really a fantastic course! I especially enjoyed the parts on encryption and cryptography in general, and I feel like I really have a good grounding in IT security now.

excellent course but the hands-on labs are buggies and even if I did it correctly still failed or got 50% and had to do it several times before it recorded accurately.

Encryption concepts were explained beautifully. As a developer with 20 years experience I got to understand things better than I understood before I took this course.

Expectation met and i'm looking forward to diving into more Google facilitated programs. I will also suggest that google gets more involved in more Coursera programs.

This course was awesome and I learned a lot about hardening a computer, network, and mobile device. I also learned what to look for when dealing with bad actors.

Замечательный курс, мне как специалисту по ИБ, очень важно расширять свои знания во всем что связано с индустрией. Особенно понравился урок про работу Kerberos.

This was very fun and well explained. The speaker was very clear and easy to understand, and a lot of useful information was given in this course in particular.
