Network and Security Foundations Study Guide
Use this study guide as an aid to assist you in understanding the 3 competencies that this course will
cover. It is important that you read the whole course. You will need to understand all the topics listed
in this study guide and reading the course is going to provide that context to help with that.
Another great aid for understanding what is discussed in this course are the cohorts that we offer. I
would highly recommend signing up and attending the cohorts.
