(Davide F, ★★★★★)

Learner’s Suggestions/Recommendations:

  • The only suggestion here is that the lab setup was a little confusing along with different versions. So a short video on explaining the basics of how to set up these labs would have been nice.
  • The course should have added at least one simple example using VM for every single issue. Otherwise the rest of the content was good and super helpful.

Is this Course worth taking?

We believe, this course clearly emphasizes hands-on learning and explains how the attack works in theory. With that, it also teaches you to actually conduct the attack in a contain virtual machine environment. The case studies, SEED labs, exercises, and other content is enough for any learner to understand the basics of internet security. Therefore, we can say this course is totally worth one’s time, effort, and money and should be taken by all those interested in internet security.
