Chapter 16 SSL VPN : The SSL VPN web portal : Portal configuration : Portal settings
  
Portal settings
A web portal defines SSL VPN user access to network resources. The portal configuration determines what SSL VPN users see when they log in to the unit. Both the Fortinet administrator and the SSL VPN user have the ability to customize the web portal settings. Portal settings are configured in VPN > SSL > Portals.
The Settings Window provides settings for configuring general, virtual desktop and security console options for your web portal.
The virtual desktop options, available for Windows XP and Windows Vista client PCs, are configured to completely isolate the SSL VPN session from the client computer’s desktop environment. All data is encrypted, including cached user credentials, browser history, cookies, temporary files, and user files created during the session. When the SSL VPN session ends normally, the files are deleted. If the session ends unexpectedly, any files that may remain will be encrypted.
Virtual desktop requires the Fortinet host check plugin. If the plugin is not present, it is automatically downloaded to the client computer.
Security control options provide cache cleaning and host checking to the clients of your web portal. Cache cleaning clears information from the client browser cache just before the SSL VPN session ends. The cache cleaner is effective only if the session terminates normally. The cache is not cleaned if the session ends unexpectedly.
Host checking enforces the client’s use of antivirus or firewall software. Each client is checked for security software that is recognized by the Windows Security Center. As an alternative, you can create a custom host check that looks for specific security software selected from the Host Check list. For more information, see “Host check”.
