Don't Use Free WiFi: These networks can be convenient and completely legit, but they can be easily set up by scammers, or even if they are “legit,” they may not be optimized for security which renders them accessible to cybercriminals.
If you don’t need to connect to a public or (potentially) unprotected WiFi network, don’t do it. Never transmit personal details or payment information via public WiFi, and be sure that any website you do visit is encrypted via SSL.
If you’re planning to do anything potentially risk online, use a VPN (virtual private network) to protect your data. Never use “free” VPN services.
Use a credit card instead of a debit card: A debit card is a code that leads directly to your cash--real money, not credit. With that code in his or her possession, a criminal can empty out your bank account. The protections on these cards are good, but not as good as a credit card. Use credit cards when traveling instead.
Do your homework: Don’t provide payment information to anyone without making sure you’re on the right site, and whoever you’re working with is in a position to provide what they’ve offered to you, whether that’s an equipment rental, an excursion or anything else vacation related.
