About the Course

I’ve heard this before – “I’m not sure my computer security practices are working”. I reply “Have you tested them?” This course is the fourth and final course in the Practical Computer Security specialization. In this course, you’ll learn how to proactively test what you have put in place to protect your data. In the first week you’ll be able to discuss the basics of deterrents and how to “trick” attackers into believing they’ve hit a goldmine of data away from your real systems. In week 2, you’ll be able to understand and discuss the steps of penetration testing methodology. In week 3, you will be able to understand and apply what you have learned on your own systems to test whether your systems are secure or not. In week 4, we’ll discuss planning for your own methodology that you can apply to your own systems. And finally in week 5, we’ll finish up with a project that will allow you to test your skills in a safe environment....

This course was an excellent introduction and overview of what security professionals face. I am non-technical and had only limited difficulty with a small portion of the materials.

Excellent course! Of the entire specialization, this is the course I've liked the most. I like that it includes both theory and practical cases, not only for the last assigment.

It wasn't exactly a walk in the park, but I enjoyed every minute of it. The lessons are easy enough to understand, even with minimal computer literacy, thanks to the Instructor's (Mr. Greg Williams) outstanding work, but the real deal comes when it's time to submit an assignment to pass the final test. It was tough (to me): but really I would do it all again. The only dark spot is represented by a less-than-active class, which could lead to up to 14 days to receive a grade (and realize that you have failed the test). Four star to the structure then, but five stars to Greg!

Pretty good course overall. The only thing I'd be upset with is the final practical implementation of OWASP, the instructor did not properly explain the instructions, and a few topics in between were haphazard.

Very informative and instructive course. It's also the most challenging part of the course.
