Well structured course, Highly recommend you go for it, if you are here looking something to start your Cyber-security career. it covers all areas in Cyber and that's what makes it a better course.

Thank you IBM.

A straighforward course. Databases were a relatively new concept but the first half of the course was all too familiar as I have encounters the concepts in Google IT Professional. A short and concise course!

It;s a very good and informative course.In one o the week the audio was not that good but still it was good...I do suggest this course to the people who want to learn basics of networking and about databases

T​his course was a little more challenging for me than some of the others, But I learned so much and loved it. There are some pre-Knowledge of code and simple stuff prob needed but that is assumed I think.

This course was very challenging, but easy to follow based on the lecture and the printed notes. I am now ready to move on the the next set of courses, realizing that cybersecurity is evolving constantly.

A great review on network infrastructure, while providing security-based content that was relatable to not only the material, but also to current cybersecurity trends.

This course will give you a indepth knowledge on network protocols, addressing layers and Databse vulnerabilities in MySQL and many more. This is an excellent course.

This course was brief only introduction to Network and Database security.

I request Coursera and IBM to launch advanced course also continuing CyberSecurity program.

Up to this point, the Network Security & Database Vulnerabilities course is the most difficult. So much information addressed in some videos - hard to consume all.

the course was excellent. I think I have gained new knowledge and skills in this networking field and waiting to learn even more additional skills in this field.

Informative courses that presented concepts, examples of actual use and requirements to assure the safety and accuracy of cybersecurity applications.

Highly recommend this course to anyone who wants to forward their career in Cyber security. The contents were highly informative and relevant.

Thank you I was able to understand the whole Network Security thing and was able to widen my understanding about Database Vulnerabilities

Estou muito satisfeito na realização deste curso, tenho certeza que irei obter melhores oportunidades de emprego a partir de agora.

Course/Module 4 taught me a lot in comparison to the previous courses/modules. It definitely got more challenging and interesting.

A very useful and enriching course .. I would recommend it to anyone interested in cybersecurity

Thank you, Coursera , IBM and MISK

This course is beneficial and actually gave me a better understanding and broader vision with the concepts! A must do course.

brilliant course, i enjoyed it very much. The only problem was the audio for the videos they were awful. please work on that

much much much better than the first three courses, and full of new and useful info, especially, the injection module

One of the best

Very detailed and a lot of video content full of explanation

One of the best coursers on the platform

It was a fantastic course, I learnt a lot.I recommend this course if you are interested in network security. Thanks!

Very interesting course made me learn many things in network security and database vulnerabilities...

thank you!...

I learn lots of things from this course.Thanks to improve my knowledge and interest in this field of cybersecurity
