What does SSL and VPN mean?
SSL (Secure Sockets Layer) is a process produced by Netscape to secure data transmission between a customer and a server. It had been soon used by the likes of Microsoft WEB BROWSER and other leading web browsers, providing a secure means to transact data in an encrypted format over the web, most seen with e-commerce sites taking credit card payments for purchases commonly.
A VPN (Virtual Private Network) is a private communications network usually used within an organization or by several companies which have a need to talk about information more than a public network. VPN traffic is carried online using standard (often insecure) protocols.
What's the fuss with SSL VPN’s?
SSL VPN technology 's been around for several years, but only in the past season has the market exploded with low priced purpose built devices actually. Famous brands Juniper, Nortel and now even Cisco have developed these low cost SSL structured VPN solutions for various business types including SMEs.
SSL VPNs just work at the application form layer. Unlike IPSEC VPNs they are far less complicated to create, support and maintain. As they work with most modern web browsers no software must be configured and they are not restricted to a particular computer. Also, as virtually all corporate networks internationally, including those with stringent firewall procedures, permit website traffic including the SSL port, SSL VPNs being employed by mobile employees are almost guaranteed to work in every environment. That is one of the downfalls of the more common IPSEC VPN technology which challenges over NAT conditions. One other benefit with SSL VPNs is it provides administrator per-user access control to a totally specified set of applications.
Summary of Benefits:
1. Low Total cost of ownership
2. End point Security in differing conditions (e.g. if no Antivirus on mobile machine, only permit extranet gain access to)
3. Clientless (browser SSL VPN gain access to for distributed folders, applications & extranet resources)
4. On demand client for full network layer access
5. Helps secure slim client access in the public domain name (Citrix, terminal services published on the net)
6. Per-user or per-group program list control
