Chapter 17 Network+ Block ___
Duncanville Engineering Academy The best start here!!!! ComSec for Network+: New Threats
Summary Students learn to manage the new threats to both computers and data in this lesson. Basic security techniques will be explained and demonstrated in order to control the local environment. External threats to the network will be observed, evaluated and removed. Engineering Connection The Network technician must evaluate and protect for a network threat proactively. These threats can be both external as well as internal. Due to the fluid nature of network attacks in the 21st century, computer security is paramount. The lesson will have the student move through an internal network securing an Ethernet bus network against known threats. The vocabulary will be given as homework, with the lab exercises demonstrating the myriad of vulnerabilities within a network as an additional assessment. Stepping Stone Detection will demonstrate current exploits and vulnerabilities in today’s networks. Contents I. II. III. IV. V. VI. VII.

Learning Objectives: The student should be able to Explain the threats to computers and data and evaluate solutions Demonstrate how to control the local environment Implement how to protect computers from networked threats Introduction:
The attacks of the 90s have metamorphosed into VoiP attacks and embedded code in OEM hardware as examples of the innovative hacker. Today, we look at how a typical hacker could use this VoiP attack and how best to protect against it, using the tools we have today.

Lecture Topics: Using MM guidelines review the security features of Windows XP and Vista and define the terms for Spam: unsolicited email pop-ups: unannounced browser windows that are sometimes difficult to close. malware (malicious software): most often a Trojan. Trojans: program that is labeled as one application but does something else. Spyware: Worms: similar to a Trojan except it travels from computer to computer. Virus: a program that leeches onto a computer, attaching itself and then executing its program. Adware Grayware Now discuss the tools used to prevent these attacks: Firewall Antivirus Encryption Certificates Incident reports When discussing bandwidth issues, utilize RET research results. Present the data and how the researching network attacks can help in both corporate and government security.
Exercise: Lab network has a native Windows firewall preinstalled. Each team must activate the firewall and then run Wireshark over lab network for 3 minutes. Analyze the results and evaluate the tools used for protection from external threats. Use RET data to compare vulnerabilities. Assessment Pre Assessment: Students list 5 types of attacks on a system and 3 ways to defend. Run lab exercise and submit lab report as per standards. Turn in vocabulary for homework. Post Assessment: Essay - Case Study:
