Network Infrastructure Security

In an internet environment, securing the network infrastructure is the foremost priority for an organization because the risks to valuable and sensitive data are greater than in a WAN environment. To eliminate potential weak points in the network infrastructure, you may opt to pass data from protocol to protocol without the complexity of decryption and encryption. To do so securely, you must have some way to securely transfer data across network protocol boundaries. The internet enables you to connect your corporate intranet to a broad public network. Although this capability provides enormous business advantages, it also poses a risk to your data and your computer system. One way of protecting the privacy and integrity of your system is to place a firewall between the public network and your intranet.
