About the Course

In this MOOC, we will learn the basic cyber security concepts, how to identify vulnerabilities/threat in a network system. We will apply CIA basic security services in the triage of recent cyberattack incidents, such as OPM data breach. We will learn the risk management framework for analyzing the risks in a network system, and apply the basic security design principles to protect the data and secure computer systems. We will examine the trustworthiness of programs and data installed in our systems and show the proper way to verify their integrity and authenticity. We will apply principle of least privileges for controlling the shared access given to different groups of users and system processes. On Amazon Cloud instances, we will use GnuPG software to generate public/private key pair for signing/verifying documents and open source software, and for encrypting documents. We will learn how to publish software, the related signature and release key on web server and publish public key to PGP key server for others to retrieve. We will learn Public Key Infrastructure (PKI) and Linux utility to serve as a CA for an organization, learn how to sign certificate request for clients or servers in secure email and web applications....

The course is excellent in terms of syllabus and objectives. IN my view, it would be even better if there were more explanations about the practical exercises

It is very good to learn basic security for the computers and Networks. Up to week 4 I learn only computer security.

Too many technical issues, for example AWS assignment cannot be mark as completed, some assignments cannot upload attachments. Instructors are not engaging in any reported issues in forum. When I contact the support, they ask me to contact AWS to resolve the AWS assignment issue, which is totally ridiculous.

It is the first subscription course I tried on coursera and it is the worst course I ever tried on coursera. Yes, all other free courses I tried are way better than this. Honestly don't get how is this poorly setup courses and assignments daring to charge fees. Totally blatant and ridiculous.

Lectures are fine, but the use of AWS instance is terrible and there is a few support .

It was quite poor compared to other courses I have taken within Coursera. The lectures not very useful, the pictures quite messy, the instructions for the assignments were not clear, the screenshots didnt match the current status (mainly regarding AWS). The bright side is some of the lectures were interesting.

Instructor is very nice and educated about the concepts, but his English is so bad that you have to follow the transcript 50% of the time in order to even understand what's being said. While reading the transcript to decipher the speaker you miss all the slides/graphics.

Its to hard to understand the Professor and the assignments are kind of hard to accomplish 100% because some of the commands and shortcuts are outdated

Here are the issues I am having with this course:

- It's really hard to understand the teacher talking.

- Quiz interrupt often while the teacher talking.

- Most of the time the teacher seems just reading only what is written on the slides, so no added value to the slides so far.

Overall, at least for now, this course seems not good at all, hopefully it will improve over time on the next weeks...

I have completed so many courses with coursera and this one seems to be the worst one. The instructor doesn't even bother to reply in the discussion forums. The AWS credits are not given inspite of filling the form multiple times. This disallows us to complete the peer graded assignments and hence hinders the completion of the course.

it was really hard to understand the instructor's speech.

PDFs for assignments are too long and distract from the main point.

Even I have send an email (it was asked in the assignment) to instructor, he did not replay to me.

Falta más acompañamiento del docente, ya que en los foros no hay nadie que ayude respecto a las dudas que uno tenga, además teniendo en cuenta que existen algunas lesiones que no son muy claras, siendo que no se explica el por qué se están realizando esos pasos para la configuración, de como serian los procesos en algo real. Creo que le falta más contenido y revisar aquellos enlaces de lectura que no están sirviendo algunos.

The instructor speech is not dynamic at all and the hight number of pdfs and steps made the assigments process difficult.

The course is good but AWS are no longer free and i m stranded in the middle of the course.

Really poorly delivered video tutorials. Spelling and grammar errors throughout. Not what I would expect from a university.

The assessment wasn’t a test of understanding, more a test of what a student could regurgitate of pointless facts from past scenarios.

I found it quite difficult to understand the professor's lectures, and even with subtitles turned on, I felt that a fair amount of the content was illegible due to the improper grammar, incomplete sentences or thoughts, and extremely slow rate of speech. The practical exercises are interesting, when they work. However, I discovered several dead links in the recommended reading assignments and practical application instructions. Lastly, the exam for week one seemed remarkably impractical, as it contained questions about specific scenarios that did were not covered in the course material. Additionally, MANY questions contained extremely poor grammar or structure and quite frankly made little to no sense. I am a big fan of Coursera and purchased an annual subscription after enjoying a course in R and Python, and was very much looking forward to this course. If I were not beyond my 7-day trial period I would be requesting a full refund and continue with future courses on a per-course fee schedule.

I had big expectations from this specialization but due to no response, I have no option to drop it. the course is very good but aws requirement is big trouble in completion. I think the Instructor should find an alternative way that ensures learner/students practice and learn. I love the instructor and the course content. I wish the course will update soon and I will rejoin the course.

The lecturer has a weak command of English and imagines that there is value in reading word for word from his slides. It's faster to read the transcript, but since it mirrors all the same faults as the spoken English, you might as well go and read a book that is written in more intelligible English.

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.

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.
