How do you shop securely online. The Center for Internet Security says you should “know your online merchants. Limit online shopping to merchants you know and trust. Only go to sites by directly typing the URL in the address bar. If you are unsure about a merchant, check with the Better Business Bureau or the Federal Trade Commission to ensure its legitimacy. Confirm the online seller’s contact information in case you have questions or problems. Use a credit card, not a debit card. Credit cards are protected by the Fair Credit Billing Act and may reduce your liability if your information is used improperly.
