Although convenient, public wireless connections are typically not secure. Your home or personal Wi-Fi system also may present security risks. TTUnet Wi-Fi service on campus is secured using industry standard and proven security practices. However, most public Wi-Fi available in retail stores, hotels, airports, and conferences are configured for convenience rather than security.

Public Wi-Fi precautions:

  • Avoid using public hot spots for important transactions, such as transactions that require a login. You should not make financial transactions or use credit cards over public Wi-Fi
  • Don't check your email or social media sites on public wireless connections, as you might expose your login information to hackers; and
  • Be sure to log out when you are done

Home Wi-Fi precautions:

  • Change the default password when setting up your home Wi-Fi
  • Enable your Wi-Fi router's strongest security features, such as WPA2
  • Disable remote administration (a feature on newer Wi-Fi routers that allows administration of the router from the Internet)
  • Make sure your home Wi-Fi access is password protected because “drive-by hackers” or your neighbors could gain access to your wireless network, steal your personal information, or participate in illegal online activities that could trace back to you; and
  • Be selective about providing access to your home Wi-Fi to guests
