CHAPTER 3: ADMINISTRATIVE FUNCTIONS 29Security Settings1. On the Setup menu, click Security, and then click Setting. The Security Settings windowappears.Figure 17 Security Configuration Window− 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 toread 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) protocolprovides a private communications channel between the KX unit and the Remote PCduring initial connection authentication. No encryption security in place duringremote KVM data transfer. SSL authentication, data encryption: Secures user names, passwords and KVMdata, including video transmissions. 128-bit Secure Sockets Layer (SSL) protocolprovides a private communications channel between the KX unit and the Remote PCduring initial connection authentication. After authentication, KVM data is alsotransferred with 128-bit encryption, but using a protocol much more efficient thanSSL (RC4 encryption, but without SSL headers). Raritan recommends this option. SSL authentication, SSL data encryption: Secures user names and passwords, andprovides high-level security for KVM data. 128-bit Secure Sockets Layer (SSL)protocol provides a private communications channel between the KX unit and theRemote PC during initial connection authentication. 128-bit SSL encryption is alsoin place during remote KVM data transfer. Note that because the SSL protocol wasnot designed for KVM communication, this mode is less efficient but no more securethan the recommended setting, above.− PC share mode – Determines global concurrent remote access, enabling up to eightremote users to simultaneously log on to one KX unit and concurrently view and control
