Wireless communication is now part of everyday life, from using 4G on your mobile phone to access the internet to using Bluetooth to listen to your music as you walk down the road. However, if your wireless device is unsecure, it can lead to data loss and maybe someone stealing funds from your bank account. Let's first look at the different types of wireless networks:

• WLAN: A WLAN is an internal corporate wireless network that sits in your Local Area Network. Normally, in a WLAN you would use WPA2 Enterprise or WPA2 CCMP as your encryption methods.
• Guest: A guest wireless network is a wireless network separate from your WLAN where contractors can access the internet, it may be used for training purposes. The guest wireless network can be used by members of staff to access the internet during their lunchtimes.
• Infrastructure: An infrastructure wireless network is where devices connect to a wireless network using a Wireless Access point (WAP).
• Ad hoc: An ad hoc network is where wireless connectivity is enabled between two devices without a WAP.
