                Whether using an in-home wireless router or mobile devices, which access public Wi-Fi, your information and devices could be vulnerable to attack. Below are some tips to help you secure your home internet and devices.

  1. Use WPA2 Encryption for your Home Route

If your router is not using encryption, your entire network is vulnerable to attack. Even if you are using WPA encryption, your network is vulnerable. WPA2 encryption with a strong passphrase is currently the safest wireless home networking option.

  1. Don’t Carelessly Connect to Unsecured Networks

If you come across an unsecured or unfamiliar network, don’t connect to it unless you know it is safe. Unsecured networks are a good way to expose your mobile devices to possible infection. If you must connect to an unsecured wireless network, try to connect to “trusted” networks like a library or café.  Also, if using public wireless, practice good internet hygiene and don’t enter any sensitive information you wouldn’t want stolen.

  1. Turn Off Your Wi-Fi and Bluetooth When Not in Use If Possible

A simple rule to protect yourself is, only turn on your device’s wireless when necessary.  If your wireless is not connected to a network, then you can’t be infected of hacked over the internet. Oddly enough this makes most “being hacked” film and TV scenes hilarious, as the solution would be to simply turn off the Wi-Fi, unplug the Ethernet cable, or pull the power cord.
