Determine the method to protect the Web servers
The company should install additional levels of security measures since it is possible for hackers to generate and send data with headers of the data looking like those sent from authorised users. Difficulties start when the hackers or attackers obtain information regarding the server, certain hosts and subnets of the Intranet.

These gateways act as intermediaries between users' systems and external systems and handle identification or authentication at a higher level than at hardware level. Every request, whether from outside or from within the Intranet system, would first be received by the proxy server, which scrutinizes the requests and prevents the undesirable and unknown ones.
