How can you ensure data is kept private online?

• A. Use public Wi-Fi for all transactions
• B. Share passwords with trusted friends
• C. Use encryption and secure passwords
• D. Save data only on local drives

Answer: (C)

Using encryption and secure passwords is essential for maintaining online privacy and protecting sensitive information. Encryption transforms data into a code that is unreadable without a specific key or password, making it significantly more difficult for unauthorized users to access or understand the data if intercepted. This is particularly important when transmitting sensitive information over the internet, such as financial transactions or personal details.

Secure passwords add another layer of protection. Strong passwords are complex, combining letters, numbers, and symbols, making them harder to guess or crack. Regularly updating passwords and using password managers can also help users maintain unique passwords for different accounts, reducing the risk of a single breach compromising multiple accounts.

Considering the other options, using public Wi-Fi can expose users to various security threats, as unsecured networks are easy targets for hackers. Sharing passwords, even with trusted friends, can lead to further risks if those individuals do not manage the information securely. Saving data only on local drives does not inherently secure the data; local drives can still be accessed by malicious software or physical theft. Therefore, utilizing encryption and secure passwords is a robust strategy for ensuring data privacy online.
