Question 4

Points: 0 out of 10

Jeff starts writing a report for one of his classes. Since the report is similar to a previous one he has written, he opens the previous report, makes changes, and re-saves the report, replacing the earlier version. Later he discovers that he still needs the first report. Which aspect of his resource (the first report) has been compromised?

 Integrity

 Availability

 Confidentiality

Feedback

Incorrect. The original report is not incorrect (which would be the case if he still had it but could not rely on its accuracy); it is simply not there because it has been overwritten with the new data.

Question 7

Points: 0 out of 10

Making data secure means keeping it secret.

 True

 False

Feedback

Incorrect. Your password needs to be secure, but that doesn’t mean it’s a secret. You need to know it in order to access your accounts. But only you need to know it. That is at the heart of security: those who need access to the data have it; those who do not need to have access to the data do not have access.

Question 8

Points: 10 out of 10

Which type of malware is most likely to pose as a security program offering to remove a virus from your computer if you sign up and pay right away?

 Spyware

 A worm

 Spam

 A Trojan horse

 A virus

 Spam

 A Trojan horse

 A worm

Question 10

Points: 10 out of 10

Which of the following is MOST likely to protect you against cybercriminal attacks?

 Having your email program remember your password

 Sharing your password only for a good reason

 Using an easy to remember password

 Keeping your software and operating system up to date

Points: 10 out of 10

If a computer is compromised, popup ads…

 increase in frequency.

 warn you to change your password.

Feedback

Correct. Receiving occasional popup ads is common. However, a constant surge of popup ads may indicate that your computer is compromised.

Question 12

Points: 10 out of 10

Everyone needs an antivirus program, but only corporate networks need to use firewalls.

 True

 False

Correct. While antivirus software scans your computer and files, firewall software monitors, blocks and filters activity between your computer and the Internet. You need both.
