− Encryption mode – click on the drop-down arrow to select one of the following:
No Encryption: Nothing is secure. The communication channel is open to anyone to
read and there is no data encryption.
SSL authentication, NO data encryption: Usernames and passwords are secured,
but KVM transmissions are not. 128-bit Secure Socket Layer (SSL) protocol
provides a private communications channel between the KX unit and the Remote PC
during initial connection authentication. No encryption security in place during
remote KVM data transfer.
SSL authentication, data encryption: Secures user names, passwords and KVM
data, including video transmissions. 128-bit Secure Sockets Layer (SSL) protocol
provides a private communications channel between the KX unit and the Remote PC
during initial connection authentication. After authentication, KVM data is also
transferred with 128-bit encryption, but using a protocol much more efficient than
SSL (RC4 encryption, but without SSL headers). Raritan recommends this option.
SSL authentication, SSL data encryption: Secures user names and passwords, and
provides high-level security for KVM data. 128-bit Secure Sockets Layer (SSL)
protocol provides a private communications channel between the KX unit and the
Remote PC during initial connection authentication. 128-bit SSL encryption is also
in place during remote KVM data transfer. Note that because the SSL protocol was
not designed for KVM communication, this mode is less efficient but no more secure
than the recommended setting, above.
− PC share mode – Determines global concurrent remote access, enabling up to eight
remote users to simultaneously log on to one KX unit and concurrently view and control
