ƒ No Encryption: Nothing is secure. The communication
channel is open to anyone to read and there is no data
encryption.
ƒ 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.
ƒ 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.
ƒ 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.
3. PC share mode - Determines global concurrent remote access,
enabling up to eight remote users to simultaneously log in to one KX
unit and concurrently view and control the same target server
through the device. Click on the drop-down arrow to select one of
the following:
ƒ Private mode (default): No PC Share. Each target server can be
accessed exclusively by only one user at a time.
