What is a VPN VPN is an acronym for Virtual Private Network. A VPN provides an encrypted and secure connection "tunnel" path from a user's machine to its destination through the public Internet. A Virtual Private Network comprised of existing dedicated networks, the Internet, or a combination of both VPN

How does VPN work ?  The VPN, remote computer must have the VPN client software installed.  When connection to the corporate network is attempted, the VPN client software will first connect to the VPN server using a tunneling protocol.  After the remote computer has been successfully authenticated, a secure connection (secret tunnel) between it and the VPN server will then be formed.  The network tunnel between them, even though established through the un- trusted Internet, is still considered secure enough that the remote computer can be trusted by local computers on the corporate LAN.

BZUPAGES.COM How does VPN works ?(Cont.)  In fact, the remote computer will even be allocated with an IP address from the Corporate IP address space by the VPN server once successfully authenticated.  It is this automatic IP address translation between ISP's IP address and the Corporate IP address offered by the VPN server which makes the remote PC look like a local computer.

VPN Characteristics  Cheaper than WANs -dedicated leased lines are very expensive.  Easier to establish than WANs  Slower than LANs -encryption/decryption takes timetypical LANS are Mbps.  dial in users are going to be typically 56Kbps.

BZUPAGES.COM VPN Characteristics (Cont.)  Less reliable than WANs –with WANs routers are under your control and performance is negotiated with provider, not so with VPN you only control initial IP connection.  Less secure than isolated LANs –because Internet is used hackers can find you –VPN protocol is one more thing to be attacked

BZUPAGES.COM VPN can work with any kind of platform and a wide variety of protocols as long as they use IP.

BZUPAGES.COM Types of VPNs  Server based  Firewall based  Router based (including VPN appliances)

BZUPAGES.COM Server based  Windows –Routing and Remote Access Service (RRAS) NT supports only PPTP, Win2000 supports PPTP, L2TP and IPSec –comes with everything needed to establish a VPN.  Linux  UNIX

BZUPAGES.COM Secure VPN: The Corporate Way  Corporations  Small Businesses  Universities  Home Users Nominate VPN ‘s as the Secure Choice !

BZUPAGES.COM Secure Site-to-Site Connectivity  Using a VPN to connect branch offices to headquarters is less expensive and provides faster access to files and applications compared to leased lines that interconnect the LANs (Local Area Networks) and WANs (Wide Area Networks).  Organizations purchase Internet connections that cost less and are faster than leased lines.

BZUPAGES.COM Secure Business to Business Connectivity  VPN’s increase secure communication and productivity with partners, customers, and suppliers by allowing them access to internal data and applications remotely.  Customers can place orders, suppliers can see inventories, and partners can access the critical and confidential information they need in real time.  Again, by using the public Internet, organizations can build extranets without an expensive private network.

Why VPN’s Corporations large and small are embracing Virtual Private Networks (VPNs) as a means to build networks that provide secure access for remote and mobile employees.
