Network Security

The Internet is a giant computer network which connects computers all over the world. Now the Internet is widely used in all spheres of the life and activity, it is first of all a way to exchange information, without which today is difficult to imagine the life. The Internet is integral part of human society and business. 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.

Network Topology →

Developing a corporate network starts from choosing equipment such as servers or routers. You should choose a topology for your network depending on your needs and budget. Thus, a star topology is cheap to implement, and mesh topology, for instance, is more reliable. This network diagram illustrates various types of computer network diagrams. Here one can find out the samples of Star, Ring, common Bus and even a rather rare fully connected network topologies. This diverse array of diagrams was created using the ConceptDraw DIAGRAM software and its solution designed especially for computer networking: design and documenting. There are more than 2 thousands graphical symbols of network equipment in the solution's vector libraries. You can create a diagram of any type network, containing any equipment and connections - no matter is it the most ancient or the super-modern networkNetwork Topology
