The following tips come from the Federal Trade Commission:

  • Avoid phishing emails. Don't open files, click on links, or download programs sent by strangers.
  • Be alert to impersonators. Don't give out personal information over the Internet (or by phone or mail) unless you've initiated the contact or know who you're dealing with. If a company that claims to have an account with you sends email asking for personal information, don't click on links in the email. Instead, contact company service through the company's website or by phone and ask whether they really sent a request.
  • Encrypt your data. To guard your online transactions, use encryption software that scrambles information you send over the Internet. A "lock" icon on the status bar of your Internet browser means your information will be safe when it's transmitted.
  • Keep passwords private. Use strong passwords with your laptop, credit, bank, and other accounts. Be creative: think of a special phrase and use the first letter of each word as your password. Substitute numbers for some words or letters. For example, "I want to see the Pacific Ocean" could become 1W2CtPo.
  • Don't over-share on social networking sites. If you post too much information about yourself, an identity thief can find information about your life, use it to answer 'challenge' questions on your accounts, and get access to your money and personal information.
  • Use security software. Install anti-virus software, anti-spyware software, and a firewall. Set your preference to update these protections often.

In addition, some free services help you guard your data:

  • Credit Karma, a lead generator that makes cash from marketing credit cards, allows you to check your information without having to ever pay for the privilege.
  • BillGuard, a New York City startup, crowd-sources fraudulent charges — that is, it lets consumers share information about scams and alerts participants to suspicious activity on their bank or credit card statements.

Finally, several commercial vendors, including the major credit rating agencies Equifax, Experian and TransUnion, offer identity-protection services.
