The best security method for employees who use their own devices for work is to keep the device software updated. Regular software updates include security patches that address vulnerabilities, reducing the risk of exploits. This preventative measure is crucial for maintaining the security integrity of not only the individual devices but also the corporate network they connect to.
Reference: Mobile and device security, including the importance of software updates, is covered in CompTIA IT Fundamentals, highlighting the best practices for securing devices used in a corporate environment.

A document that explains how to use a software program is an example of a written work that expresses the original ideas of the developer. A copyright is a legal protection that grants the developer the exclusive right to publish, distribute, and control the use of the document.

This pseudocode snippet correctly implements the requirement to apply a cost-of-living increase to employees making less than $15 per hour. By using a loop (For all employees in the list), it ensures that every employee meeting the condition (making less than $15 per hour) will have their salary adjusted by multiplying it by
1.032. This approach efficiently processes each relevant entry just once and applies the necessary increase accurately.

Explanation
Eavesdropping is an electronic attack where digital communications are intercepted by an individual whom they are not intended1. This is a confidentiality concern because it violates the principle of limiting access to information to authorized people only. Confidentiality is a set of rules that limits access to information1.
Eavesdropping can compromise the secrecy of the information and expose sensitive data to unauthorized parties. References:

A variable is the best option to store a test score entered using a web form. In programming, variables are used to store data values that can change over time, such as user input. The variable can be set to store the score when the user submits it, allowing the program to manipulate or display the score later as needed.References:
The use of variables for data storage and manipulation is a basic programming concept covered in CompTIA IT Fundamentals and other introductory programming courses.
