VPN WLAN

Because the WLAN inherently offers poor encryption techniques to protect
your transmission, you may find that deploying an IPsec type of virtual
private network (VPN) will further enhance your ability to protect
your transmission, through encryption. If a hacker does find a way to
decipher the WEP encryption of your WLAN, it won’t do him or her any
good, because the underlying transmission has its own encryption algorithm.
This is really the best method of making certain your transmissions
are not intercepted by any malicious user.

When you implement encryption, it is imperative that you use the
highest strength possible, due to the confidential nature of network
data. Since computers have become faster and more powerful, it is much
easier for these devices to decipher your encryption algorithm. The less
powerful your encryption scheme, the easier and faster it is for a computer
to decipher your wireless network transmission.
