* LOCK DOWN YOUR LOGIN. The NCSA said bulk up your accounts with stronger passwords (different characters, capitalization, numbers...preferably eight characters or more). Even better, consider stronger tools like biometrics (fingerprints), security keys or apps that enable one-time access codes.
* KEEP A CLEAN MACHINE. Update your malware, spam-blocker and security software before the trip. Keep apps updated during your trip, too.
* MAKE SURE ALL DEVICES ARE PASSWORD-PROTECTED. Always enable a locking feature, too, that's opened by something more than just a finger swipe.
* BE DISCREET. OWN YOUR ONLINE PRESENCE. Remember, when you show off your vacation to family and friends on social media, you're potentially telling the bad guys back home -- that you're not home! Be sure to set your privacy and security settings so that only the people you want to see your travel fun see it.
