Issue/Introduction
We have some target servers RedHat 7, on the servers, system team config VNC encryption with some type: TLSVNC, TLSPlain, X509None, X509Vnc, X509Plain.
But CA PAM can't access the target server by using the VNC method, with the warning "unsupported security type. No Security type supported. Server sent '[19,19]' security type, but we do not support any of their."![]("C:\cases\CA PAM Cases\31799211 - VNC Encryption\VNC encryption.png")
Does CA PAM support connection to the target server via the VNC encryption method?
Cause
The VNC implementation is not TLS. From the desktop to PAM it goes through a TLS tunnel (UP>spfd) but thereafter is in the clear if you are using the embedded VNC client.
Environment
Release : 3.3.x
Component : PRIVILEGED ACCESS MANAGEMENT
Resolution
Currently we don't have a solution for this, VNC Encryption support is not yet on the Product road map, if this is required do open as an idea under the 'ideation' tab of Braodcom Communities.
