8/16-Port KVM over IP Switch 

71 / 92 

 

6.6.3 Security

 

 

Figure 6-27. Device Security   

 Force HTTPS  

 

If this option is enabled access to the web front-end is only possible using an HTTPS 
connection. The IP-KVM switch will not listen on the HTTP port for incoming connections. 

In case you want to create your own SSL certificate that is used to identify the IP-KVM 
switch refer to the Section called 

Certificate

 KVM encryption  

 

This option controls the encryption of the RFB protocol. RFB is used by the Remote 
Console to transmit both the screen data to the administrator machine and keyboard and 
mouse data back to the host. If set to “Off” no encryption will be used. If set to ”Try” the 
applet tries to make an encrypted connection. In case connection establishment fails for 
any reason an unencrypted connection will be used. 

If set to “Force” the applet tries to make an encrypted connection with certificate. An error 
will be reported in case connection establishment fails.
