Who should consider using encryption?
Whilst encryption will add an overhead (extra data having to be transmitted between router and client) and therefore decrease overall speed of connection slightly, we would still strongly recommend it is employed by anyone implementing a wireless network. Interception of unencrypted data allows an attacker to read anything that you are sending between your client and router. If you use (for example) online banking, then the benefits of encrypting the data are clear. VPN connections provide a significantly higher level of encryption, and also provide the added benefit of using equipment other than your Wireless Access Points or Clients to encrypt and decrypt data. Using a VPN to transmit data to and from a remote site adds a further level of security for tele-workers using wireless connections in addition to wireless encryption.
