About the Course

This course covers a wide variety of IT security concepts, tools, and best practices. It introduces threats and attacks and the many ways they can show up. We’ll give you some background of encryption algorithms and how they’re used to safeguard data. Then, we’ll dive into the three As of information security: authentication, authorization, and accounting. We’ll also cover network security solutions, ranging from firewalls to Wifi encryption options. The course is rounded out by putting all these elements together into a multi-layered, in-depth security architecture, followed by recommendations on how to integrate a culture of security into your organization or team. At the end of this course, you’ll understand: ● how various encryption algorithms and techniques work as well as their benefits and limitations. ● various authentication systems and types. ● the difference between authentication and authorization. ● how to evaluate potential risks and recommend ways to reduce risk. ● best practices for securing a network. ● how to help others to grasp security concepts and protect themselves. ● new AI skills from Google experts to help complete IT tasks....

A very comprehensive look at IT Security. I've learned everything from encryption and decryption to whitelisting, and how it pertains to real-world scenarios. Very useful to learn when it comes to IT.

I loved the whole experience beginning to end. I came in already having a BA from state university. Well organized, well produced, and combined with note-taking this course is a no-brainer. Go for it!

I appreciate all who tried their best to make this course, but it just didn't work out for me as well as i wanted. I feel like i didn't retain much information, and that a lot of words and topics were thrown at me so quickly. There were virtually no useful or practical things to do to help us learn hands on either. There were also a lot of things that were not explained properly in depth and that are skimmed over. There are even things mentioned in previous lessons or sections that we don't learn about until much later, but is also glossed over a bit. I dont mean to bash the instructors and the other people behind the scenes who put this together, but at a certain point, i honestly just downloaded the text from the videos to teach myself better. Some videos is someone just reading the text with no prompts or diagrams for 7+ minutes, and videos that have prompts are...almost useless to be honest. I appreciate the attempt at diagrams, but they're not really useful to follow along that much. Anyway, there's more to unpack but my fingers hurt lol. There was some good, like i learned a lot of cool stuff, even tho little portions of the information wasn't useful to my graded quizzes. I hope this course works out for any others that wanna try it. its good to get your feet wet in IT.

I like the part about how tcp/ip works the most. The security stuff was a bit over my head. I worked with printers years ago and used to see issues with laptops that couldn't print quite often. I read online that Jewish vocational service has a program where they say you need google IT and they can get you a job, but the economy isn't so good anymore, so that may no longer be true. I used to fix printers at work for 12 years and occasionally diagnose a bad laptop for IT. Maybe it's beyond the technology, but they need to put a bad pc in front of the students online and tell us the problem , so we can diagnose it. I used to see corrupt operating systems that stopped printing, laptops not getting required updates and extremely slow pcs with full hard drives. They need examples of broken pcs. I even saw a pc that spat out gibberish on startup. The bios on the motherboard was corrupted somehow.

-Not very well structured; probably you could categorize better the topics of weeks 5 and 6. For example, the steps of incident handling are not very clearly differentiated: I assume they are detection, contention, correction, and testing... but I could also set analysis and recovery as separate steps.

-Some topics include too much in-depth information, like different forms of authentication, making it difficult to discriminate important information and technical details. Also, the way they are presented makes difficult to differentiate which of them are intended for authn., for authz. or for both.

-Final project evaluation was disappointing. I spent several days working and researching just to find out that I could had input "lorem ipsum" in the textbox to get approved. I expected some specific feedback or peer reviews like in other courses.

I loved this course! I feel bad giving three stars because the material was obviously 4 stars/maybe even 5 stars!

What needs work:

He is why I did not give it an additional star: The quizes were too lenient. There should be some kind of punishment or drawback to failing too many times, other than having to wait 24 hours to try again. Also, I think a larger question pool that questions for quizes are pulled form would be better so students can't just retake the same quiz and pass it that way.

And maybe remove the step-by-step in the qwiklabs.

What was great:

The host and the information presented.

The aditional readings.

What would be nice: A list of all the further readins at the end, or maybe even a printable sheet with organization names and their duties and maybe a "cheat sheet" with commonly encountered software/command line tools

I found this course experienced issues similar to the The Bits and Bytes of Computer Networking course. The content covered is mostly fine. There seems to be a tendency to cover too many concepts at once, then to either gloss over complicated concepts or to focus on them for a significant portion of the module. I found this often meant I was stuck in certain areas.

This was not helped by the quizzes which sometimes have poorly worded questions and ambiguous answers. Even in content I felt confident with, I often had to repeat quizzes due to lack of clarity in the questions and/or answers.

Overall, it is worth completing this course. I found it to be the most frustrating course out of the five IT courses. The content is worth learning and I hope the course can be reviewed to provide a better learning flow.

The course was pretty good up until courses 4 and 5. Both went on far too long than they should've and a lot of info is covered in the Cybersecurity Professional course. Course 5 especially just dragged on and on and both had concepts in quizzes that hadn't even been touched on. For example, PAAS and others were covered in the second module, but then common cloud models (which actively describe these) isn't mentioned until well into module 5. In fact, I had to go find my own references for these. A huge thing however is just how out of date this course is. This is from at least 2017, 2018 and it's rather ironic to talk about keeping things updated when Google is promoting a course from nearly 7 years ago.

I understand that the course only meant to serve as a jumping point but some retrofit is needed in terms of preparation and course work. Some areas are too vague and doesn't allow significant resources other than what is suggested on wikipedia and similar sites. Not alot of people tend to complete readings as a resource considering that they are paying for it each month as well.

Work on improving word assignments. Often times its too vague and doesnt provide enough details or the requirements/limitations. Provide a sample submission or document, this i'm seeing people strugglign with because they still dont understand the concepts laid out by the course.

More animation would be appreciated as it helps in understanding like how the hardware and even software works as just by reading it doesnt help much anyhow i have to google it again to understand it in a better way. And i even think that explanation was not up to the mark as it lagged in the detail explanation it was like he explained things just from the surface like in wep he didnt explain like how eavesdropper is able to watch on communication between access point and user with shared key and in the same topic he didnt explained why we need two same encryption message to recover the shared key

The course content and material was well prepared but I would strongly suggest this in the future delivery of the course. I personally suggest going more in depth of those terminology rather than just briefly explaining them in just 6-10 mins video should help more for an individual with 0% knowledge on IT security. It wasn't so much of challenge to me because of my pervious experience with IT security but newbies would definitely find it hard to follow in the course perfectly. Just my own thoughts.

Thank you
