Professor consistently drops the ball and allows the AWS credits to expire inside this course. You cannot complete it as of 12/20/2019. Coursera is not able to fix this, Amazon says to talk to Coursera. Coursera says to talk to the Professor, and the Professor doesn't respond to his campus emails.

Never got added to the AWS student profile by the Professor and therefore couldn't submit first week assignment although I have emailed the Professor to add me in the Student Profile.

I am really having a hard time understanding the instructor and the tasks given are hard since there is no help or little information provided.

this is not beginner course, very hard to listen without subtilties, and the aws lab its a disaster

No access to Amazon classroom. Impossible to pass the specialization.

communication isn't clear

Excellent course. Very well explained public/private key using gpg and Public Key Infrastructure with OpenSSL. Several links need to be updated.

This is a very intuitive and flexible course upon deadlines. The instructor has control over the course hence making understanding very simple

Excellent course on security, good teacher, good material and especially very good practical material.

Complicado si no tienes conocimientos mínimos de Linux pero muy satisfactorio por el reto

I got the yearly subscription and didnt mind to spend time on this on top of other planned courses. I will not pay for this course. Don't get me wrong, the material is good and as a beginner I learnt a lot. But the general lack of maintenance for this course is not worth it to pay. Some other (free courses) has an active TA who at least takes care of the questions. Nobody answers anything here. But saying that, I still managed to finish the course with some common sense so its fine. I am kind of thankful too because the assignments kind of forced me to learn Linux. First exam had unexpected questions and some questions were not worded properly but I kind of got the hang of Prof Chow's style and managed to benefit from his teaching.

The courses are very interesting but the fact of letting someone whose English accent is very bad, even if he is PhD, is not a good idea, Also he is not that charming person who will seed in the student the passion and love to keep going on. I only finished the first course and I was always telling my self "when will this course end?" because I was not feeling that cool mood. In Enterprise system management and security specialization PhD Greg Williams was such cool, clear and very informative so that any student will keep studying, that's what I mean, I wish if this specialization was also presented by him.

Conclusion: Coursera must enforce pedagogic and regular course material update policies!!

I enjoyed this course, though it was challenging. I reviewed each video several times and studied the reading assignments. The hands on projects are essential to understanding the material. The professor provided rich examples that can be valuable as future references. Very practical and useful course for Linux and network security.

Some parts tough enough, a good command of linux will help a lot. Instructors accent can be hard to understand sometimes and text transcript can be hit and miss. Enjoyable course to do over all
