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 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.

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

Too much of camera work and the shot of instructors, who is reading the texts. The texts sounded like more in a written-format, which is a little bit hard to understand by listening to the instructor. The visual slide should be presented longer while the instructor is explaining the material. More slides could be utilized to help us understand complicated terms, systems and protocols. Also that way, I think it would be easier for the learners to memorize via visual in addition to the aural discussion.

This course could have used smaller sections with more practical guidance. The videos mainly consisted of 1 person talking to the camera with a blast of a huge amount of information. This course at times was quite unbearable to get through. I understood some security concepts and the final project section with a rundown of how to implement the security controls for the organization was the one section where I feel it could help in real-world scenarios.

Overall this is a decent overview of security topics. I think the videos could be improved - there are too many 'talking heads' and not enough diagrammatic explanation. Also, the transcripts vary in places from what the speaker is saying - I suspect they are being created automatically.

I had no problems with the online labs, although I think that some instructions might cause learners difficulty whose first language is not English.

I feel like there is still a lot more to learn. This course covers a little bit of everything but not very in depth. I believe I will continue to get my CompTia certs, as those are a lot more in depth. This course felt like a good preview of what a career in IT is all about, however I do not feel confident enough in my knowledge yet to begin a career.

I was looking forward to this course yet it was very disappointing that the instructor's delivery of the course was from a textbook. very hard to understand the content delivered unlike the previous courses in this certificate, not enough practical exercises as well, and feeling like i need to find and do another security course elsewhere

Even though it shared a lot of information I believe that it needs to be updated with current and more relevant material. The instructor read off a lot of information that was given to him obviously but it needs to be a little better. I hate to say that I actually lost interest half way through the course.

Technical details on encryption algorithms and cypher methods to secure a network/IT infrastructure; Antivirus/malware detection and prevention; Disk encryption and growing a security-oriented company culture; All these aspects are interesting and useful to know from the Tech support role POV;

Good information, but the when you get an answer wrong on the quizzes it tells you to go back and read a certain part of the chapter. But the videos and information isn't listed the same when you're looking at an overview of the course so it's difficult to find what video need to review.

This course, unlike the courses before, lacked visuals. Some of the concepts could have been explained better...I rewatched the videos to understand these concepts better, but that didn 't help. Eventually, I found much better explanations on youtube or other websites.

you really should use more animations in order to convey an abstract or conceptual point. when looking up the different types of encryption on wikipedia, they do a better job demonstrating it. where as, you guys do a better job of explaining the encryption process.

It's a good course, but not very comprehensive; they lay a lot of terms on you one right after the other and barely explain each one. Learning material is subpar at best as well; visuals are few and far between and many aren't properly marked or explained.

I was expecting a little more in depth coverage of the topics with labs to go with them. I think this course should be split in two and maybe earlier courses like the first and second course could be coalesced into one since they contain less material.

Sadly I did not enjoy the last module of this Certificate.Even thought all the information was important and interesting,the examples were lacking and the introduction to the knowleadge learnt in a real-life situation were barely there.

Enjoyed the clear presentation on the subjects. Did not care for the jumping back and forth from windows to linux. Felt that a more linear approach would be better for new learners. Also it does seem that the labs need to be updated

This course was completely different than its predecessors in terms of mode of delivery. A lot of narrative descriptions, lots and lots of boring definitions and less practicality i.e.: supplemental reading in the form of videos.

if you have ADHD be ready to READ, take a lot of notes and watch the videos a bunch of times. it was more difficult for me unlike all the reviews i saw about it. glad i did it hopefully i can find a job now!

This course would greatly benefit if more practical exercises were included. The theoretical background was broad and well presented, but the shortage of actual exercises made it too transitory

It's a great course! The only thing that isn't so good for me is the final project. You'll have to wait for someone (another student) to view and grade your project. And this takes some days!

The Course is amazing but lacks a lot of visual presentation and too much data to process without any supplemental material that visualizes the process sometimes.

Otherwise good course

A lot of unimportant and difficult information and details and a lot of things that cause confusion,, there is very little practical duties without learning it its lessons

Some parts of it are very technically dense without much need for this level. Longer and more frequent quizes would be helpful, as well as labs and other exercises.
