Title: Module 12 Introduction
Course: CNT 2001 Computer Networks & Communications > Section: Module 12 Network Access Security

Introduction

We will explore in detail the concepts and tools that are used to protect networks, including firewalls and encryption. We will examine authentication techniques to allow access to those who should have access, while denying access to others. And, we will explore the use of policies and procedures to manage the use of networks by people.

Learning Objectives:

- Explain what firewalls are.
- Explain how firewalls block unwanted access to a network.
- List some common features of firewalls.
