Describe what an administrator must do to turn on and configure encryption in a wireless network.

What will be an ideal response?

To set up encryption, an administrator turns on encryption at the WAP and generate a unique security key. Then he configures all connected wireless nodes on the network with the same key information. An administrator can either generate a set of encryption keys automatically or do it manually. The encryption level, key, and passphrase must match on the wireless client node or communication fails. Many access points have the capability to export the encryption key data onto removable media for easy importing onto a client workstation, or an administrator can configure encryption manually using the vendor-supplied configuration utility.
