Preview: ... se PVCs remain permanent and does not disconnect itself from network with each session. These permanent virtual circuits may exist for few weeks, months or years and are assigned their ending point which does not change. These PVCs are available for transmitting and receiving data all the time in an analogous or a leased line connection. <br><br>Frame relay has an ability to support several PVCs simultaneously and make a direct connection to multiple sites using single physical connection. Frame relay reduces physical network complexities without affecting higher level network functions. Frame relay uses higher level protocols to its advantage and provides a common network transport for multiple traffic types.<br><br><br>Virtual Private Network (VPN)<br><br>The network design we chose to implement supports remote access through dial-up and VPN connection. <br> <br>Remote access through dial-up requires a remote access client to connect to a remote access server using a telephone line. This type of remote access client requires at least one modem or multi-port adapter as well as telephone line or other form of connectivity. To access resource on private network the remote access server must also be configured with a LAN connection. <br>Advantages of Dial-up Remote Access solution:<br><br> Connections are inexpensive to implement on remote access client.<br>.<br> Dial-up connections are relatively inexpensive comparatively.<br><br> It provides reliable remote access solution.<br><br> Relatively simple to implement<br><br><br>Disadvantage of Dial-up Remote Access Solution:<br><br> Hardware required on the remote access server can be expensive.<br><br> Data transmission rate is generally slow.<br><br> Dial-up remote access connection is generally unreliable depending on the location of remote access user.<br><br><br>Second option for us for rem ...

Preview: ... and well-tested (Rescorla). It is important to note that SSL/TLS based VPNs are able to encrypt link traffic for site-to-site connectivity just like IPSec VPNs. The RSA handshake (or DH) is used exactly as IKE in IPSec, and the SSL crypto library is used to secure the symmetric tunnel after that, again using similar encryption techniques to those protecting IPSec tunnels (RSA Laboratories, 2004). This tunnel can pass arbitrary traffic, just like an IPSec VPN. <br><br>IPSec is a standard set of protocols and rules for their use that allow the creation of VPNs. The theory was if vendors implement IPSec to create their VPN products, they would interoperate with other vendors products (Schneier and Ferguson, 2006). IPSec creates a secure tunnel by first using a handshake protocol called Internet Key Exchange (IKE). IKE authenticates the end points of the tunnel to each other, and then follows a secure procedure to exchange the necessary information to create a more permanent tunnel using symmetric encryption (Phifer, 2005). Once this tunnel is in place, any arbitrary traffic sent between these two end points will be passed through the protected tunnel. This tunnel can be used by any application or protocol and is semi-permanent, meaning it will stay up indefinitely provided both end points continue to desire its existence (Schneier and Ferguson, 2006). <br>When comparing VPN products, there are several items that most people look for. Open VPN excels at many of these points. One of the biggest problems with IPSec VPNs is their complexity. <br>This complexity provides many opportunities for administrators to undermine the security of their devices. Open VPN provides strong simple default configurations that fit most implementation needs. Open VPN can be configured and installed by someone with basic security knowledge while still maint ...
