An online transaction refers to a business transaction that is made over electronic systems Whether you go online to check your bank balance, pay a bill, give money, shop, or sell something, these six rules can help you keep the risks to a minimum.
Defend your computer against Internet threats.
Help protect your online transactions by using firewall, antivirus, and antispyware software. Encrypt your wireless connection at home. Keep all software (including your web browser) current with automatic updates. For more information, see How to boost your malware defence and protect your PC.
Create strong passwords.
Strong passwords are easy for you to remember but difficult for others to guess. They are at least 14 characters long (the longer the password, the better) and include numbers, symbols, and upper and lower case letters. For more information, see Learn how to create strong passwords. If you already have a password in mind, check your password strength.)
Keep passwords and PINs (personal identification numbers) secret.
Do not share them in email, instant messages, or over the phone. Use unique passwords for bank accounts and other important financial information. Avoid using the same password everywhere. If someone steals that password, all the information that the password protects is at risk.
Find the web address yourself
Links in email messages, text messages, instant messages, or pop-up ads can take you to websites that look legitimate but are not. To visit websites, type the address yourself or use your own bookmark or favorite.
Look for signs that your information is safe
Before you enter sensitive data on a web page, ensure that the webpage is “secure” by checking for padlock symbol.
The site uses encryption, a security measure that helps protect your data as it traverses the Internet. Signs of encryption include a web address with https (“s” stands for secure) and a closed padlock beside it. (The lock might also be in the lower right corner of the window.) Make sure that you are at the correct website—for example, at your bank’s site, not a fake one. If you are using Internet Explorer, one sign of trustworthiness is a green address bar like the one above.
Save financial transactions for your home computer
Never pay bills, bank, shop, or do other financial business on a public or shared computer or on devices such as laptops or mobile phones that are on public wireless networks. The security is unreliable.
Use common sense
To protect yourself against fraud, watch out for scams. For example, be wary of deals that sound too good to be true, alerts from your “bank” that your account will be closed unless you take some immediate action, notices that you have won a lottery, or a refusal to meet in person for a local transaction.
Typically this kind of message, whether sent by computer or phone, is designed to entice you to visit a phony website where criminals collect your financial data. (If you doubt the message’s authenticity, call the company.) Learn to spot phishing scams and defend against them.
What to do if there are problems
Online shopping problem? First, ask the seller to make things right. If that doesn’t work, contact the web service for help.
Report scams, fraud, identity theft, or other abuse to the web service, local police, and the bank, credit card company, or other financial institution.
