Okay, sure, using multiple passwords can be a pain, but - hey, didn't I just say this? - convenience is the enemy of security. If somebody hacks one account and it's easy to guess the credential to other accounts. That kind of behavior only makes you more vulnerable.
Ditch Facebook ... or Constrain It.
Facebook is a huge repository of consumer PPI and it's only becoming more sophisticated at revealing private details about your life to others. Those details make it easier to case (or investigate) who you are and what you do online. Leaving Facebook, though, may not be entirely an option, so your next best approach would be to constrain what Facebook shares about you. Check out Facebook's Privacy Settings and seriously limit what Facebook shares about you.
Ditch Microsoft Windows ... or Constrain It.
The Microsoft Windows operating system is less secure than Mac O/S or Linux; security experts recommend avoiding using the product. Still, chances are, your behaviors are already changing and you're using more secure operating systems found on your phones (iOS and Android) for transferring critical PPI, and that's probably a good thing and a strategy for containing your risk. If you can't abandon Windows, at least curtail your banking and utility payments on the platform in favor of paying by mobile apps. The less PPI you share on Windows, all the better.
Use Google's Chrome Browser. On Every Device. Optimize it's Privacy. Install HTTPS Everywhere.
Google Chrome is a browser designed around better Internet security. It's faster and more secure than Windows Internet Explorer and Mozilla's Firefox. Chrome is free and available for all platforms: PC, Mac, iOS, and Android. Install Chrome and optimize it's privacy features. Then, install HTTPS Everywhere: a free tool built in to Chrome that forces a secure connection to the places you go on the Internet.
Invest in Teathering.
Teathering refers to using your cell phone as a data hotspot. Carrier plans that include teathering are really inexpensive these days and are considered a standard feature. Instead of using public wifi access points (which can be designed as a honeypot to have unsuspecting users connect to it and expose PPI), you'd want to teather your laptop or tablet computers against your mobile device. Your cell carrier is ultimately more secure than any random wifi hotspot you might find in the field. It'll help keep the information you transfer confidential and private.
Reduce Your Attack Profile.
Be conscious of where you share your personal private information; who you give your business card and personal information to. Question why somebody wants a critical identifier like a driver's license or a Social Security Number and even consider not doing business with these people. Limit your applications for credit and your banking products to a single provider. Don't sign up for everything you see online and delete online accounts that are no longer in use. Shred any physical documents instead of throwing them into the mail. Sit down with your spouse or partner and discuss strategies for limiting each other's exposure. Be conscious and take specific actions to reduce how someone could acquire your PPI and exploit a vulnerability.
Be Conscious of Social Engineering.
Imagine being in a checkout lane at the supermarket. You have somebody behind you looking at their phone. Meanwhile, you remove your credit card and swipe it, then, enter a PIN code, into a reader device in plain sight. All the while, the guy behind you on the phone is recording your activities, capturing your card data and PIN on video. Your assumption of privacy got the best of you. Be aware of your surroundings and of those who may be using electronic devices around you. Take immediate action to protect yourself.
