Security is a must when dealing with a data network, this is why you have to take the proper precautions of coming up with a system to protect a business from any intruders, hackers, or anything of that nature. For most businesses you need a strong firewall and proxy to keep unwanted people out. You will also need a strong Anti-virus software and Internet Security Software. For authentication, you must use strong passwords and change it on a bi-weekly/monthly basis. When using a wireless connection, you must have a robust password. You also must raise awareness about physical security to employees. Finally, you must implement an optional network analyzer or network monitor.
First, let me also explain what a network is, in particular a computer network. A computer network is a group of interconnected computers. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of some types and categories and presents the basic components of a network. Networks can be
classified according to the topologies. There are a variety of topologies including bus, ring, star, mesh, Star-bus, Tree or hierarchical topology network. The bus, ring, and star are the ones commonly used when trying to run a corporate company. I would recommend a star configuration when doing so. The purpose behind using the star configuration is based off the fact that a star configuration connects all cables to a central point of concentration. This point is usually a hub or switch. Nodes communicate across the network by passing data through the hub. The reason why I wouldn't use a ring configuration is mainly due to the fact that the ring configuration is pretty much obsolete in situations like this where we are applying network topology to a huge corporation. The reason why I wouldn't use a bus configuration is because it does not cope well with heavy data... [continues]
