Businesses are experiencing an increasing need to provide telecommuting for teleworkers, small branch locations, business partners and customers. They always need, independent from their location, access to company information and expect an easy and especially safe access to the necessary network resources everywhere, every time and with every device. However, how do businesses ensure that the safe access is real secure? Is nobody listening in? To achieve this goal, secure, available and costeffective remote access is critical for businesses. You need to be absolutely sure that remote access is always available and of all things completely secure.for this reason, most companies use virtual private networks (VPNs) to guarantee secure connection. City Requirement Company VPN Access via WiFi Home Office Partner Site IP Phone SOHO VPN Gateway WiFi Hotspot Requirement - Same access as in the central site Air Port Public Access Network Network Access Requirement VPN through Firewall Hotel Central Site Internet Kiosk Dial or Broadband Requirement Quick connection VPN Gateway AAA Application Servers Servers Requirement Access to company applications Graphic: Secure remote access via VPN is a widespread requirement

4 Types of Secure connections - Virtual Private Networks (VPNs) A virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines. A secure VPN is a combination of tunneling, encryption, authentication, access control and auditing. It is used to transport traffic over the Internet or any insecure network that uses TCP/IP for communication. Virtual Private Networks (VPNs) are the right solution for a reliable and safe remote access into the company. With the explosion of broadband, mobile devices and online tools, teleworking is on the rise. VPN can easily enable this connection to become a safe, quick and cost effective remote working solution. Generally there are two primary methods for deploying remoteaccess VPNs: IPSec and SSL. Each method has its advantages based on your networking requirements. IPSec VPNs Internet Protocol Security (IPSec) is a standards-based VPN that offers flexible solutions for secure data communications across a public network like the Internet. IPSec is built around a number of standardized cryptographic techniques to provide confidentiality data integrity and authentication at the IP layer. Connections are established using VPN client software preinstalled on the user desktop, making it primarily useful on company-managed desktops. The following figure is an example of an IPSec VPN tunnel. X Internet VPN Tunnel 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 provide VPN network access to remote users. Since SSL (the Secure Socket Layer protocol) is used no security software installation is required. Remote users can use Internet Explorer or other standard web browsers. There are two SSL VPN network access modes: reverse proxy and full tunnel. Reverse Proxy Mode Full Tunnel Mode LAN ( x) LAN ( x) Web-based Application Internet Web Mail File Share Internet Web Mail File Share Web-based Application Application Server Non-Web

5 Why choose IPSec VPN IPSec vs SSL VPNs IPsec and SSL VPN each have their own advantages, so what is better may often come down to what is most suited for your network. The following matrix is introducing difference between IPSec and SSL VPN. Criterion IPSec VPN SSL VPN Network Environment and Device Type of connection Fixed connection Transient connection Cost high fixed/low-variable (the box does all the work) moderate fixed/high-variable (manage client software) Scalability Easily deployed and scalable Scalable on server side Type of device Enterprise owned and managed Managed or unmanaged Users Remote or branch office - Mobile employees Business partners Customers Applications and content Applications Supported All IP-based services Web-enabled applications, File sharing, But under some conditions, IPSec VPN is better than SSL VPN. IPSec VPN is best suited for point-to-point access. When business need a permanent connection between two specific locations, such as between a branch or remote office and a corporate headquarters. It can be used successfully to provide acces to a small finite number of remote workers using company-managed laptops.
