CompTIA Security+, Part 1 of 8: Network Security

Course description

In this course we will discuss the plethora of security devices found on the network. As a security professional you need to understand how these devices work, the methods used to implement security, and the design considerations needed when deploying them. We will cover all of these topics while keeping our focus on the security of the network. Security should be at the forefront of priorities, not an afterthought. This class will be a step in becoming a security conscientious individual. This course will cover the CompTIA Security+ objectives 1.1, 1.2, and 1.3.

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 the user has working knowledge of networks and networking. Ideally, the user should have their CompTIA Network+ certification, but can be replaced with networking experience.
