Security Level Security Level Features
Authentication Only
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 clear text, data packets are vulnerable to
eavesdropping attacks. Do not select this if you are exchanging
sensitive information.
Authentication and Low Level
Encryption
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".
Authentication and High Level
Encryption
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 higher security than
"Authentication and Low Level Encryption".
