CompTIA Security+ Question K-51

Which of the following can a security administrator implement on mobile devices that will help prevent unwanted people from viewing the data if the device is left unattended?

A. Screen lock
B. Voice encryption
C. GPS tracking
D. Device encryption

Answer: A

Explanation:
Screen-lock is a security feature that requires the user to enter a PIN or a password after a short period of inactivity before they can access the system again. This feature ensures that if your device is left unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications.

CompTIA Security+ Question I-5

Jane, an IT security technician, needs to create a way to secure company mobile devices. Which of the following BEST meets this need?

A. Implement voice encryption, pop-up blockers, and host-based firewalls.
B. Implement firewalls, network access control, and strong passwords.
C. Implement screen locks, device encryption, and remote wipe capabilities.
D. Implement application patch management, antivirus, and locking cabinets.

Answer: C

Explanation:
Screen-lock is a security feature that requires the user to enter a password after a short period of inactivity before they can access the system again. This feature ensures that if your device is left unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications. Device encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen. Remote wipe is the process of deleting data on a device in the event that the device is stolen. This is performed over remote connections such as the mobile phone service or the internet connection and helps ensure that sensitive data is not accessed by unauthorized people.

CompTIA Security+ Question H-35

Which of the following controls can be used to prevent the disclosure of sensitive information stored on a mobile device’s removable media in the event that the device is lost or stolen?

A. Hashing
B. Screen locks
C. Device password
D. Encryption

Answer: D

Explanation:
Encryption is used to ensure the confidentiality of information.

CompTIA Security+ Question G-8

Which of the following is the primary security concern when deploying a mobile device on a network?

A. Strong authentication
B. Interoperability
C. Data security
D. Cloud storage technique

Answer: C

Explanation:
Mobile devices, such as laptops, tablet computers, and smartphones, provide security challenges above those of desktop workstations, servers, and such in that they leave the office and this increases the odds of their theft which makes data security a real concern. At a bare minimum, the following security measures should be in place on mobile devices: Screen lock, Strong password, Device encryption, Remote Wipe or Sanitation, voice encryption, GPS tracking, Application control, storage segmentation, asses tracking and device access control.

CompTIA Security+ Question E-2

Which of the following controls can be implemented together to prevent data loss in the event of theft of a mobile device storing sensitive information? (Select TWO).

A. Full device encryption
B. Screen locks
C. GPS
D. Asset tracking
E. Inventory control

Answer: A,B

Explanation:
A: Device encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.

B: Screen locks are a security feature that requires the user to enter a PIN or a password after a short period of inactivity before they can access the system again. This feature ensures that if your device is left unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications.

CompTIA Security+ Question C-7

Which of the following can be used on a smartphone to BEST protect against sensitive data loss if the device is stolen? (Select TWO).

A. Tethering
B. Screen lock PIN
C. Remote wipe
D. Email password
E. GPS tracking
F. Device encryption

Answer: C,F

Explanation:
C: Remote wipe is the process of deleting data on a device in the event that the device is stolen. This is performed over remote connections such as the mobile phone service or the internet connection and helps ensure that sensitive data is not accessed by unauthorized people.

F: Device encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.

CompTIA Security+ Simulation 7

A Security administrator wants to implement strong security on the company smart phones and terminal servers located in the data center. Drag and Drop the applicable controls to each asset type.

Instructions: Controls can be used multiple times and not all placeholders needs to be filled. When you have completed the simulation, Please select Done to submit.

Correct Answer:


Cable locks are used as a hardware lock mechanism – thus best used on a Data Center Terminal Server.

Network monitors are also known as sniffers – thus best used on a Data Center Terminal Server.

Install antivirus software. Antivirus software should be installed and definitions kept current on all hosts. Antivirus software should run on the server as well as on every workstation. In addition to active monitoring of incoming fi les, scans should be conducted regularly to catch any infections that have slipped through- thus best used on a Data Center Terminal Server.

Proximity readers are used as part of physical barriers which makes it more appropriate to use on a center’s entrance to protect the terminal server.

Mentor app is an Apple application used for personal development and is best used on a mobile device such as a smart phone.

Remote wipe is an application that can be used on devices that are stolen to keep data safe. It is basically a command to a phone that will remotely clear the data on that phone. This process is known as a remote wipe, and it is intended to be used if the phone is stolen or going to another user.

Should a device be stolen, GPS (Global Positioning System) tracking can be used to identify its location and allow authorities to find it – thus best used on a smart phone.

Screen Lock is where the display should be configured to time out after a short period of inactivity and the screen locked with a password. To be able to access the system again, the user must provide the password. After a certain number of attempts, the user should not be allowed to attempt any additional logons; this is called lockout – thus best used on a smart phone.

Strong Password since passwords are always important, but even more so when you consider that the device could be stolen and in the possession of someone who has unlimited access and time to try various values – thus best use strong passwords on a smartphone as it can be stolen more easily than a terminal server in a data center.

Device Encryption- Data should be encrypted on the device so that if it does fall into the wrong hands, it cannot be accessed in a usable form without the correct passwords. It is recommended to you use Trusted Platform Module (TPM) for all mobile devices where possible.

Use pop-up blockers. Not only are pop-ups irritating, but they are also a security threat. Pop-ups (including pop-unders) represent unwanted programs running on the system, and they can jeopardize the system’s well-being. This will be more effective on a mobile device rather than a terminal server.

Use host-based firewalls. A firewall is the first line of defense against attackers and malware. Almost every current operating system includes a firewall, and most are turned on by Default- thus best used on a Data Center Terminal Server.
