What is an important step in protecting personal and financial information when shopping online?

Answer Details

When shopping online, protecting personal and financial information is critical because data transmitted over the internet can be intercepted by malicious actors. The most important step a consumer can take is to verify that the website uses HTTPS (Hypertext Transfer Protocol Secure) and displays a lock icon in the browser's address bar. HTTPS encrypts the data exchanged between the user's browser and the website's server, making it extremely difficult for third parties to read sensitive details such as credit card numbers, passwords, and personal addresses.

Verifying the website's HTTPS and lock icon in the address bar is the correct answer because it directly addresses the security of the data transmission channel before any sensitive information is entered.

The remaining options all represent risky behaviours. Saving login credentials on public computers exposes accounts to anyone who uses that computer afterwards. Public Wi-Fi networks are often unencrypted, making it easy for attackers to intercept data. Sharing sensitive information on social media makes it publicly accessible and can be exploited for identity theft or fraud.
