SSL VPN: -

An SSL VPN (Secure Sockets Layer virtual private network) is a form of VPN that can be used with a standard Web browser. In contrast to the traditional IPsec (Internet Protocol Security) VPN, an SSL VPN does not require the installation of specialized client software on end users' computers.
The SSL VPN can be a good choice for schools, libraries and public kiosks where trust can be an issue but easy access is also important. Applications include Web-based e-mail, business and government directories, databases for educational institutions, file sharing, remote backup, remote system management and consumer-level e-commerce.
