When using a wireless network on a cruise, first make sure you are using the ship’s network by asking for the specific names of the ship’s legitimate networks so you recognize them when you connect. Anytime you enter a password, even for webmail or Facebook, verify that you have a secure connection in the browser address bar. Look for https:// -- the "s" is for secure - - and the locked security padlock icon. You must click the padlock and read the information to confirm you are at the right site; otherwise you could have a secure connection to a hacker site instead. These steps confirm you have a strongly encrypted link directly to the desired site, and your communications will be "scrambled" so anyone eavesdropping on the public hotspot Wi-Fi communications cannot understand or use any of your information.
