Where can I obtain the VPN Client to tunnel into the Social Sciences network

You can find the VPN Client for Windows OS, Mac 0SX, Linux, and Solaris here: SSC VPN 
 The SSC Virtual Private Network ( VPN ) Service allows you to access SSC resources as if you were part of the SSC Network. A VPN is a secured private network connection built on top of publicly accessible infrastructure. The SSC VPN has more stringent security parameters than the UCLA Campus VPN . This is necessary so that access can be tunneled through the SSC Firewall.
