CompTIA Security+, Part 2 of 8: Security Services

Course description

In this course we will discuss the OSI and TCP/IP model. We will discuss the vast number of applications found on networks and how they communicate. We will discuss their uses, their security, and as a security practitioner how you can utilize them to increase security on the network. We will finish this course by discussing wireless communication and the inherent risk with using that as our communication means. This course will cover the CompTIA Security+ objectives 1.4 and 1.5.

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.
