But the serious question for network engineers, designers, lawmakers and enforcers is the need for protect the Internet networks from the Internet crimes, hacking and attacks.
There are many kinds of dangers and ways of attacks, but there are also quite a number of hardware, software and physical methods of protection against them. Such devices as routers, IDS and Firewalls are examples of hardware devices used for network security. Anti-virus software and VPNs are some of the software network security tools.
One of the most effective and easily implemented ways to protect the networks is the use of Firewalls. The Firewall is a first line of defense against the external threats to networks, it can be either software based or hardware based. The main task of firewall is to allow the authorized access to a computer while blocking unauthorized access. The Network layer firewalls makes decisions based on the source address, destination address and ports in individual IP packets. Modern network layer firewalls maintain internal information about states of the connections passing through them.
Depending of the service kind and security you need for your network, you can choose the type of firewall. The most useful types of firewalls are: Screened host firewall, Screened subnet firewall, Packet filer firewall, Stateful inspection firewall, Hybrid firewall, Proxy server firewall, Application level (gateway) firewall.

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.
