City Requirement Company VPN Access via WiFi Home Office Partner Site WiFi Hotspot SOHO VPN Gateway IP Phone Network Access Requirement - Same access as in the central site Public Access Network Air Port Requirement Firewall VPN through Hotel Central Site Dial or Broadband Internet Kiosk Requirement Quick connection VPN Gateway AAA Application Servers Servers Requirement Access to company applications Graphic: Secure remote access via VPN is a widespread requirement Types of Secure connections - Virtual Private Networks (VPNs) A virtual private network (VPN) provides secure communications With the explosion of broadband, mobile devices and online tools, between sites without the expense of leased site-to-site teleworking is on the rise. VPN can easily enable this connection to lines. A secure VPN is a combination of tunneling, encryption, become a safe, quick and cost effective remote working solution. authentication, access control and auditing. It is used to transport Generally there are two primary methods for deploying remote- traffic over the Internet or any insecure network that uses TCP/IP access VPNs: IPSec and SSL.

IPSec is built around a number of desktops. The following figure is an example of an IPSec VPN standardized cryptographic techniques to provide confidentiality tunnel. data integrity and authentication at the IP layer. Connections Internet VPN Tunnel X Y A B Graphic: The VPN tunnel connects the firewall (X) and the remote (peer) IPSec router (Y). These routers then connect the local network (A) and remote network (B). SSL VPNs A Secure Socket Layer Virtual Private Network (SSL VPN) uses SSL to required. Remote users can use Internet Explorer or other standard provide VPN network access to remote users. Since SSL (the Secure web browsers. There are two SSL VPN network access modes: Socket Layer protocol) is used no security software installation is reverse proxy and full tunnel.
