Since the data is sent in cleartext, data packets are vulnerable to
eavesdropping attacks. Do not select this if you are exchanging
sensitive information.
Select this level if you want to encrypt the data packets as well as
authenticate the transmission partner and prevent unauthorized
packet tampering. Packet encryption helps prevent
eavesdropping attacks. This level provides less security than
"Authentication and High Level Encryption".
