The late-year holidays (Thanksgiving, Hanukkah, Christmas) are known for travel, visiting with friends and family, and gift giving and receiving. Any time of year is a time for sharing some details of our lives with others through social media outlets such as FaceBook, Twitter, MySpace, and personal blogs.
During this time of year, it is especially important that you protect yourself from online threats, some of which are caused by others, and some of which are caused by you! Follow these steps to keep your property and your online presence safe during the holidays:
Don’t announce your travel in advance. If you post something like, “leaving home for Philadelphia for five days”, you are announcing to the world that your home may be vacant for extended periods of time, inviting burglaries. Make your posts more vague, such as “spending Christmas with brothers and parents”, which might be where you live, or not.
Don’t gloat about your gifts. Similarly, if you talk about your new Kinect, Wii, or iPad online, you may be sharing news of your loot with too many outsiders. Instead, be more discrete and share news about your new things more privately.
Limit FaceBook exposure. Check your privacy settings in FaceBook. Consider setting up one or more groups of family and friends, to limit how wide your announcements are sent. My wife and I have “immediate family”, “family”, and other groups of highly-trusted individuals with whom we may share things about travel, gifts, and other personal matters, so that the entire world doesn’t know that we might not be home at the moment. Similarly, limit the FaceBook applications that you allow to access your personal data. Some FaceBook applications are malevolent and are designed to steal your information and use it against you.
Get a security tune-up. Follow easy steps to ensure that your anti-virus and firewall are working, and that your patches and browser are up to date. Do this before you shop online, to limit the chances that your credit cards will be compromised.
Secure your home Wi-Fi. Find the instructions to improve the security of your home router or Wi-Fi access point. Change from no security to WEP, or better yet, WPA. While WEP is not as secure these days, it’s better than nothing. WPA or WPA2 are far better, and most PCs (and even gaming consoles) supports WPA and WPA2 these days.
Limit use of public Wi-Fi hotspots. From road warriors to housewives, we roam with our laptops from hotspot to hotspot at our favorite coffee shops and other public venues. While it’s okay to check the news and get shopping information, it is not okay to check e-mail, log on to FaceBook or Twitter, or perform high-value activities such as online shopping from an open WiFi hotspot. Easy to use tools are widely available that permit even the unskilled to hijack your session and compromise your personal information.
Check your credit. U.S. consumers can check their credit three times per year for free (once per year for each of the three credit bureaus). Check your credit report carefully, looking for any accounts that you may not have opened, or for changes in accounts you may not have authorized.
Use a separate online shopping credit card. Rather than using your primary credit/debit card for online shopping, open a second account and use only that one. Keep a low balance to minimize your exposures.
Choose “credit” when using debit/credit cards. Whenever you are making purchases with your debit/credit card, choose “Credit”. Then, if your credit card number is later compromised, you may enjoy additional protection (such as the $50 liability limit) on your account. Many banks do not offer the same protection for compromised debit card numbers.
