Solution

If i have intranet servers and i have to provide security for them then i will provide security by using Firewall.

Firewall:As name suggests that it is wall that is built in order to keep fire away.In computer server,we can say,it is mechanism that keep different kind of threats away from computer system and gives securityFirewall has keen eye on each and every packet that goes inside or outside of network.It acts as wall between outside world and your server network.Firewall can be in the form of Software as well as Hardware.In our intranet server,we can use Packet filter firewall.It is type of firewall in which it decides whether to allow packet or discard packet based on the IP address and port which are used by packet for transmission.It maintains some kin of rules that allows packet to enter in network server,it packet does not satisfy that rule then it is not accepted.Packet filters are mainly work in Network Layer but we can implement another types of firewall on different layers of TCP/IP such as applicationn layer,hardware layer etc.Proxy servers are also type of firewall which act as intermediate between server and user.It checks every packet from user and forward to proper server.
