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 cleartext, 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".
The following table lists the settings that are automatically configured according to the security
