Have an online shopping addiction? Be sure you follow these general rules so you don't become the victim of an online credit card scam!

• Use a single credit card for all online purchases: It's best to use a credit card for all online charges (vs. a debit card), since credit cards offer the most protection against fraud. Additionally, designate just one credit card for all online purchases.
• Monitor charges: The most basic thing you can do is to keep an eye on your designated card's charges. Review your monthly statements, and call your credit card company if you see any suspicious activity or mysterious charges.
• Don't download unknown attachments: Received a flier in your inbox for an awesome sale? Be sure you know who sent it first — downloading malicious documents to your computer is a quick and surefire way for hackers to get to your personal data.
• Use https where you can: Connect to sites using a secure connection by typing "https://" before the website address. HTTP (which stands for "hyper text transfer protocol") signifies the transfer of information between web servers and clients, whereas HTTPS signifies a secure connection (S for "secure") — your browser is talking to the server in a secure, encrypted connection. You'll notice it frequently on banking and other sites that contain personal information, and sport a green URL.

Between tablets, smartphones, and the ever-present home computer, kids are pretty tech-savvy these days. Still, keep any online dangers at bay with some practical safety measures.

• Talk about Internet safety: When your children are old enough to take the wheel on the World Wide Web, it's time to have "the talk." Maybe even go so far as to post a list of Internet dos and don'ts at the family computer desk (which should be in view of a common area at all times to prevent sneak-surfing) to remind the little ones of the rules.
• Enable parental controls: Enabling parental controls on a Mac is simple (System Preferences > Parental Controls), and a PC isn't difficult either (Control Panel > Internet Options > Content). But you do need to take the time to actually establish your parental control guidelines, which could take some time.
• Practice safe surfing — Sit with your kids while they surf the Internet, and maybe even show them how you use it. Visit your Facebook pages together, browse their favorite online games, and help them decide what is appropriate. Setting a good example will show them that while there are a lot of scary things online, you can still navigate it safely.
• Enable browser extensions: Firefox, Chrome, and Safari all offer great extensions, and there are plenty out there that help your kids surf safely and responsibly. Just search "parental control" in any of these add-on stores, and you'll find a number of extensions that block sites, password protect, and keep credit card info away from your connection.

Outwit potential hackers by staying password smart.

When joining the latest social network du jour, follow these best practices.

• Create an alternate email address for account sign-up: If you don't want to be found, then sign up for your social networking sites — from Flickr, Facebook, and Twitter — with a secondary or alternate email address so that when people search for you based on the email in their contact list, they don't find you immediately. This will allow you more control over who can see your profiles. If your accounts are already set up, then change the default email to a new one to prevent any new snoops. You may also consider using one email account when you sign up for sites in an effort to keep your social networking organized.
• Disable all GPS/locator apps and settings: Don't want people to know you're tweeting from the coffee shop around the corner from your ex's place at 9 a.m. on Sunday? Don't tweet with your location enabled, and don't sign up for Google Latitude, which will allow friends insight into your locale.
