Citrix just released a security advisory article regarding the SSL “poodle” vulnerability and how we can disable SSL 3.0 protocol on the Netscaler -> http://support.citrix.com/article/ctx200238
The article shows how we can disable SSL on vServers and on NSIP, MIP and SNIPs.
It is also possible to use SSL profiles, this allows us to create profiles for front-end services (vServers) and for backend services (services to the servers)
SSL profiles can be created under System –> Profiles –> SSL Profiles –> Create new
From within here we can choose what protocols we want to have enabled. Note that Citrix Receiver only supports TLS1 and not version 1.1 and 1.2 (which also cannot be used on a VPX)
