Safe and Secure Online: Computer Security Tips for Nationwide.com

Create a strong password and protect it. Never share your username or password with others. If you have trouble remembering a password, write yourself a hint, not the actual password. Use a different password for each site because if one password is compromised, the rest of your information is not in jeopardy.

Install a firewall. Your computer's first line of defense is a firewall. It protects your machine from hackers and intruders by keeping out unwanted or unauthorized traffic. You can set the level of protection and the software determines what traffic may access your computer.

Use updated antivirus and antispyware software. Antivirus software protects your computer from viruses – unauthorized computer code that is spread from one computer to another, destroying files and interrupting normal operations. Antispyware software will search and destroy programs designed to gather electronic information about your computer. Spyware can change your home page or generate pop-up ads while you're surfing. The most malicious spyware contains a keystroke logger that records each letter you type, including usernames and passwords, and sends the information to someone who uses that information to steal your identity.

Automatically update crucial software. Set your operating system and security software to automatically update. By choosing this setting, you'll receive the latest files available from the software manufacturers. As vulnerabilities are discovered and exploited, you'll be protected form the latest threats.

Recognize phishing emails and fraudulent scams. Never respond to an email or pop-up asking for personal information, such as your username, password or account number, no matter how official it looks. Instead, call the customer service number that is published on the company's printed material.

Download cautiously. There are many free games, utilities and other software that may be useful, but some contain viruses or spyware. Only download from reputable manufactures or trusted sites.

Use a credit card. If you shop on-line, use a credit card (not a debit card with access to your bank accounts). Credit card companies offer better protection against unauthorized use of your account. Ask your credit card company if they can provide a virtual account number that is valid for a single purchase so you won't have to give the merchant your permanent card number.

Avoid using public computers. Don't use computers libraries, hotels or airports to conduct personal business. You can not be assured that these systems have the proper security in place. The same is true when using your computer on a wireless network. Save financial and personal business for your own computer that you know is more secure.

Disconnect when you're finished. Turning off your computer when it's not in use reduces the chance that another computer can access it. And, you'll save energy too.
