Peripheral Device Security

5 minutes 5 Questions

Peripheral Device Security involves ensuring the integrity, confidentiality, and availability of data and resources associated with peripheral devices. It encompasses guard measures to protect sensitive information from unauthorized access, tampering, or theft. Part of device security involves proper authentication and access controls to prevent unauthorized usage and data exfiltration. Additionally, it focuses on protecting devices from malware and other cyber threats that might compromise data or negatively impact device functionality. Device security also includes securely disposing of old devices and ensuring the regulations regarding data storage and transmission are followed. In some instances, encryption and secure data transfer protocols may be required to maintain security compliance. To maintain device security effectively, it is crucial to stay up-to-date on the latest threats, vulnerabilities, and best practices in the field.

Peripheral Device Security

Peripheral Device Security is an essential aspect of overall computer safety. Without securing your output and input devices, your entire system can be at risk.
The term Peripheral Device Security encompasses practices that prevent unauthorized access, misuse, malfunction, modification or damage to peripheral devices connected to your system. These can include keyboards, webcams, printers, external hard drives and more.
Knowing how peripheral device security works is crucial. It involves securing the hardware, environment, software or communication links related to peripheral devices. Techniques include using lockable equipment, secure storage areas, secure network links, shields or cages to protect from physical damage, encryption techniques, latest drivers, firewalls, anti-virus or anti-malware and the most critical, secure disposal of device when it is no longer in use.

How to answer questions regarding Peripheral Device Security in an exam:
To answer questions on this topic during exams, here are some tips:

  1. Read the question carefully: Before answering, make sure you understand what the question is asking purely. Is it about hardware or software security? Does it refer to a specific type of peripheral device?
  2. Use technical language: Show your knowledge by appropriately using technical terms and jargon. Instead of saying 'protecting the device,' say 'implementing hardware or software security measures.'
  3. Be concise and precise: Examiners usually prefer precise and brief answers. Remember, the goal is to display your knowledge without rambling.

Exam Tips: Answering Questions on Peripheral Device Security:
Familiarize yourself with current peripheral security technologies and recent threats. Having a solid understanding of these will allow you to confidently answer a variety of questions. And last but not least, practice, practice, practice! The more you practice answering questions on this topic, the more comfortable you will become.
Good luck!

CompTIA A+ - Peripheral Devices Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

A user notices that their mouse is functioning erratically. Which action should be taken to troubleshoot the issue?

Correct Answer: Check that the mouse's sensor is clean

A dirty sensor can cause erratic movement in a mouse. Checking and cleaning the sensor is the first step to troubleshooting the issue. Other suggestions, such as reinstalling the operating system or enabling Bluetooth, will not address the root cause of the problem.

Question 2

An employee has received a new wireless keyboard and is having issues with interference from other devices. Which wireless keyboard feature should they look for when purchasing a replacement?

Correct Answer: Keyboard with frequency hopping

A keyboard with frequency hopping is the best choice to mitigate interference from other wireless devices. Frequency hopping allows the keyboard to rapidly switch between different radio frequencies, making it less susceptible to interference from other devices operating on the same or nearby frequencies. Solar power is irrelevant to reducing interference. Mechanical switches are a preference for key feel and durability, but do not affect wireless performance. A built-in touchpad is a convenience feature unrelated to the wireless functionality and interference resistance of the keyboard.

Question 3

A company allows employees to bring personal USB storage devices to transfer files. Which security measure would best protect the network from potential malware?

Correct Answer: Implementing and enforcing a policy of only using authorized USB devices

Implementing and enforcing a policy of only using authorized USB devices is the best measure to protect the network from potential malware introduced by personal USB storage devices. This ensures that only USB devices that have been vetted and approved by the company's IT department are allowed to connect to company computers, reducing the risk of malware infection. Making employees sign an agreement is not as effective as actually enforcing the policy through technical means. Relying solely on antivirus software is not sufficient, as it may not catch all threats, and it's better to prevent the introduction of malware in the first place. Disabling USB ports entirely is too restrictive and would prevent the use of legitimate USB devices, hindering productivity.
