Clientless SSL for Remote Access

摘要

OK, confess, you've been in this situation before. From a public terminal, you had to send your password unencrypted to a server on your corporate intranet. You looked around and hit "enter," hoping that no one was sniffing your network traffic. F5 Networks' FirePass SSL VPN appliance deals with this scenario by letting mobile users establish a secure, clientless remote connection to your intranet through a Web browser. The device comes in two models: the FirePass 1000, which supports up to 100 users; and the FirePass 4000, which supports 1,000 users and can be scaled to 10,000 using multiple devices. Unlike an IPsec (IP security) VPN, the FirePass does not require client software to be pre-installed and configured on the remote PC. Instead, it works directly through a Web browser using a virtual desktop Web page or by dynamically installing client software that establishes an SSL tunnel via a virtual network adapter.
