Unit 9: Lesson 9 Lab 9.6

Purpose

In this lab, you will familiarize yourself with various computer threats and learn about the damage they can do to your computer and network.

Lab Instructions

In this lab you will evaluate the world of computer viruses and malware, as well as the type and number of threats that have been cataloged. You will research industry-leading sites to learn how to identify viruses and malware.

In uCertify, in section 9.6 of the Lab, review and provide your written experiences and recommendations for each of the lab questions.

Lesson 9 provided background on the large number of threats to your computer’s

security. Most threats are in the malware group, and new viruses and threats are

released on a regular basis to join the cadre of those already in existence. It’s a

good idea to be aware of the threats that are out there and to keep up-to-date on

new ones being introduced into the wild.

One great source to find this information is the CERT/CC Current Activity web

page at US-CERT. There you’ll find a detailed description of the most current

viruses as well as links to pages on older threats. You can also find updates on

most anti-malware companies’ websites, such as Norton (for Norton Security)

and McAfee. Google searches can also make you aware of threats or provide

news on recent attacks.

Submission requirements: o Answer each of the questions with a written paragraph of 2-3 sentences o Add an image (snip-it or screenshot) showing what you found (where

applicable)

Unit 9: Lesson 9 Lab 9.6

Here are a few specific questions for you to answer:

1. Pick a recent date. How many viruses and malware were “discovered” on that date? (Alternate question: How many were added to your antivirus program on a given date?)

2. Are there any serious security threats currently out there?

3. Which virus or worm caused the most damage in history? How many computers did it infect and how fast did it spread?

4. Can you find example names of some different types of viruses? Choose a few, such as a polymorphic virus, a boot virus, and a multipartite virus.

5. What is the most popular ransomware in history?

6. What is the name of the most common backdoor you can find?

7. What are examples of password-cracking software?
