Select this level if you want to authenticate the transmission
partner and prevent unauthorized data tampering, but not
perform data packet encryption.
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".
