This course provides a brief introduction to network architecture, operations, intrusion tactics, and security hardening. Learners will also be introduced to common network protocols and how systems use the TCP/IP model to communicate within a network. Learners will gain an understanding of network level vulnerabilities and how to secure a network against those vulnerabilities. Network security topics will include firewalls, virtual private networks (VPNs), system hardening, and virtual private networks. By the end of this course, you will: - Describe the structure of different computer networks. - Illustrate how data is sent and received over a network. - Recognize common network protocols. - Identify common network security measures and protocols. - Explain how to secure a network against intrusion tactics. - Compare and contrast local networks to cloud computing. - Explain the different types of system hardening techniques.

it was amazing and all the concepts were simply explained . thank uh coursera for making it easier for me to understand these new topics to me in such a convient and simplified way
DZ
I had to do this while sick and injured...BRUTAL. But this course WILL teach you the working skills of it. Just make sure to know how to set up your computer when you go to work and you're good.

Very clear, well explained videos. I tend to lose interest with video learning but I was kept engaged. Very enjoyable course helping you absorb lots of information quickly like a sponge.
NH
It seemed very in-depth which is nice for someone like me who has no prior knowledge of this subject matter, however it seemed like a big jump in complexity from the previous course.
PK
I am truly satisfied with the available lectures and also reading section of the course which strengthen concepts in more detail. Thanks a lot GOOGLE for launching such fascinating and amazing course.

I recommend this class to everyone who wants understand how to secure a network. It's to the point, fairly sufficient, easy to learn, and you can also do independent practice
GC
Wonderful instructor! The information was boilerplate and the TCP information was a bit tricky but he still made learning accessible. Extremely inspirational and I will miss him!
AK
Its was wonderful experience to partcipate in this course. Now I am more confident about the Networks and Network security after successfully completion of this course. Thanks Google
KW
A comprehensive and easy to understand course for anyone looking to become and entry level cybersecurity analyst or just further their knowledge in protecting their own VMs!
SW
I really enjoyed the information and the activities particularly because it gives you the feeling that you actually attended a security incident which makes learning more interactive
SB
A LOT of theory a bit to little practices IMO, they just throw you in, and "solve this", without properly guiding you, could be improved.Great teacher tho, explains everything neatly.
OS
The topics covered are cool and thought-provoking, particularly on how malicious actors can penetrate into a network. The activities in the course are interesting and fun to do.

It's basically the same as online college. Them talking at you and a whole bunch of reading, which you'll eventually forget. No hands-on practice at all
I enjoyed this course more than the others since beginning the Google Cybersecurity Certification. It covers a lot of information, but makes it very digestible to the average person.

The course was very boring, could not understand much, no hands on experience just writing a documenting stuffs. I really did not understand what was that exemplars activity was about without guiding nicely.
Severely lacks depth. Lacks hands-on element.
Simply amazing, just LOTS of resources and new information. Couldn't have asked for a better explanation to be honest. Felt overwhelming sometimes but I loved every detail about this one!
These were all new concepts for me, and the teachers at Google did a great job breaking down the concepts and putting them into bite-sized pieces so I could understand and learn them.
The lack of examples and guidance was super frustrating, and the how to read the logs information provided was not very helpful either. A lesson should've been provided on how to actually interpret and use the resources. I had to rely on youtube and other sources for a lot of further explanation. I would've liked to see them use their Rhyme program for some of these activities, it would've been super helpful in making the example reports.
Google's Cybersecurity Specialisation Course 3 was challenging as expected. However the content was good in covering the following concepts for beginners:
-Network components/devices/diagrams
-TCP/IP model, OSI model
-IPv4 vs IPv6 components
-firewall/VPN/subnet/CIDR
-types of network attacks, DDoS
-OS hardening techniques
-network hardening techniques (such as where to place firewall, intrusion detection or prevention systems IDS/IPS in a network and visualised using example network diagrams)
Sweet and straight to the point , content is good, some assignment could be made more interactive than just text and jarring text to read . but otherwise you learn a lot
I'll be honest, this course nearly turned me off of this certificate entirely. The concepts themselves were not challenging - I can memorize anything. There was a complete lack of context provided in the videos and readings. How am I supposed to relate these dozens of new concepts to anything without real world examples? Shoving a dictionary full of acronyms in my face is not learning. Giving me weird metaphors to decipher about houses and letters is not learning. I found myself seeking (free!) resources outside of this course to better understand the terms introduced to me (YouTube, cybersecurity forums, etc). I used flashcards to memorize protocols and found myself needing to constantly review my notes prior to jumping in to a new session. The worst part is that after finally completing this course, it is so very clear to me that network security is easily the most important domain - it is the birthplace of keeping data within an organization secure. And yet it has been the least accessible course thus far.
I feel like the videos did not align well with the text content and the larger projects seemed too large and overwhelming - I would've preferred a more gradual project introduction. The text content should enforce what the video content showed, not introduce entirely new information.
This course is the most formal education about networks and network security. Other courses from different organizations teach a lot but they are not as formal as they need to be. This can be greatly important for interview preparations as well as learning the core concepts about networking at a foundational level.
I am happy that I am able to learn and grow my education on my time of study is a amazing feeling. Its a spectacular offer to not be interested and further your education. Thank you Coursera
I gave this course only 3 stars due to it being extremely overwhelming. It was really long and a lot of information to review.
really antiquated exploration of DOS attacks
No hands-on experience
Very lengthy and complex to understand but all aspects are covered very precisely and effectively to manage network protocols and assess threats while practicing security methods.
Had a mesmerizing and fun experience doing this course as it makes networks fundamentals strong and crisp to remember.
I am truly satisfied with the available lectures and also reading section of the course which strengthen concepts in more detail. Thanks a lot GOOGLE for launching such fascinating and amazing course.
Like guiding through network and security elements ... fast. Challenging and rich in content but not going into too deep. The following courses in the certificate will delve deeper, I imagine.
