CASP, Part 2 of 9: Network Security

LearnNow Online
Updated Aug 21, 2018

Course description

Addressing for computer communications can seem overwhelming, but this course will give you an overview of IP and MAC addressing to help make the process more approachable. We will examine the source and destination addresses for network frames and packets, and discuss TCP and UDP to understand how reliable these protocols may or may not be in different circumstances. In addition, network security, such as secure design practices and secure communications, will be discussed as well as firewalls, DMZs, network access control and more. Finally, we’ll look at online security using SSL and TLS and Domain Naming Services, or DNS. This course is part of a series covering the CompTIA Advanced Security Practitioner (CASP).

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.


Prerequisites

This course assumes that you have familiarity with information technology, basic networking, and basic security concepts. No scripting or “hacking” experience is required. Having windows command line experience as well as having administrative rights on your machine will be helpful.
