Terms in this set (20)
1. Due to a recent string of thefts in your office, you need to harden your local system. What two actions are most appropriate for your situation? (Choose two.)
A. Install a hardware lock
B. Disable unused services
C. Install antimalware
D. Enable encryption
All four answers are device-hardening options. If you are worried about local theft, installing a hardware lock is a must. In addition, if your device does get stolen, encryption will prevent thieves from accessing your files unless they know your username and password.
2. What option can you configure on your workstation to increase security when you leave your desk?
A. File encryption
B. Multifactor authentication
C. Single sign-on
D. Screensaver password
A screensaver password will require someone to enter your password to gain access to the computer. File encryption won't help if the attacker has access to the computer as you.
3. You have just landed at the airport and have an unexpected six-hour layover. You want to use your smartphone to get some work done. What should you disable as a precautionary device hardening measure to help prevent potential attacks? (Choose two.)
B. Bluetooth C. NFC D. FFC
3. B, C.
You should disable Bluetooth and Near Field Communications (NFC) to help prevent attacks. Autofill is a browser setting. There is no FFC in this context.
.4. Claire, a co-worker, is browsing the Internet and wants to know if it's safe to enter her credit card information into a website. What do you tell her to look for?
Secure websites start with HTTPS://. Also tell her to look for the lock symbol nearby.

A. They logged on and disabled encryption.
B. They used the Disk Recovery tool to access the encrypted files.
C. All users logging into the system have access to encrypted files.

6. A, B, C.
Adware can give you a barrage of pop-ups as well as cause browser and search engine redirection.
7. Which type of software will help protect your computer from malicious network traffic?
A. Software firewall

9. Your manager just got a new workstation and is not part of a domain. He wants to know which user accounts he should disable to increase security. What should you tell him to disable?
C. Power Users
Disabling the Guest account is a good security measure to reduce the number of entry points a potential attacker could use. You cannot disable the Administrator account, although renaming it is a good idea.
10. Which of the following actions is not considered a web-browsing best practice? A. Limiting the use of PII B. Disabling Autofill C. Closing untrusted source warnings D. Updating plugins and toolbars
You should recognize untrusted source warnings and act on them appropriately. Good practices include limiting the use of personally identifiable information (PII), disabling Autofill, and updating plugins, toolbars, and extensions.
11. The managers at your company have decided to implement stricter security policies. Which of the following login schemes will help them achieve this goal?
A. Single sign-on
B. Multifactor authentication
C. Password confidentiality
Multifactor authentication increases security by requiring users to use more than one method to authenticate. They need to use two or more items among something they know, something they have, and something they are.
12. Your coworker Rachel has recently discovered that when she starts typing her name into a field in a web browser, her whole name appears as well as her address in the appropriate boxes. What is this due to?
A. Adware infection
B. Single sign-on
C. Suspicious hyperlinks
Rachel is experiencing Autofill, which is a feature in a browser that automatically populates your information in the right fields when you start entering any of the information. It can be convenient, but it can also be a potential security risk.
13. You have been asked to give training on network security. For your section on password management, which options should you recommend to users? (Choose two.)
A. Do not use complex passwords because they are easy to forget.
B. Change default passwords on systems.
C. Use the same password on multiple systems so they are easy to remember.
D. Do not reuse the same password after you are required to change it.

16. Which of the following are considered characteristics of a strong password? (Choose two.)
B. Uses patterns
C. Uses symbols, numbers, and letters
D. Contains PII
16. A, C.

17. You just read an article about an Internet worm recently causing problems. What type of software should you install to protect yourself from this worm?
