Title: Module 11 Introduction
Course: CNT 2001 Computer Networks & Communications > Section: Module 11 Basic Network Security

Introduction

You can not hide a network away and use that network at the same time. All networks must be accessible in some way, so all networks are vulnerable to attack and misuse. We will examine the basic threats and attacks that are used against networks, and we will examine the basic security techniques that are used to protect networks. We will examine the tools that are used to protect networks and to attack networks.

Learning Objectives:

- Describe some basic network security considerations.
- Explain what social engineering is and how it is the most successful method to circumvent security measures.
- Describe a method for creating very secure passwords that are easy to remember.
- Discuss what identity theft is and ways to avoid it.
- Compare the difference is between viruses, worms, and Trojans.
- Discuss different types of attacks used by hackers to cause harm on networks.
- Explain what rogue access points are and different ways locate them.
- You learned different methods of countering some of the attacks covered in this lesson.
- Explain why physical security is just as important as other types of security on a network.
- Discuss the difference between secure and unsecure protocols.
- List some examples of secure and unsecure protocols.
- Explain what encryption works.
- Explain what certificates are and how they are used in networking.
- Explain what authentication is.
- Explain what RADIUS and TACACS+ are and how they are different.
- Explain what CHAP, MS-CHAP, and EAP are and how they differ from each other.
- Discuss some commonly used networking tools.
