Networks and Data Security

The concept of a network is pretty simple, multiple computers or devices connected in order for users to share data or connections.  Where it becomes more complex is the varying types of networks and ensuring they are secure.


First there is the Local Area Network, known also as the LAN.  The LAN is a smaller network focusing on a small area such as a home or office.  The configuration is done one of two ways:

1. Peer to Peer
2. Client/Server

With a peer to peer LAN this basically means there is a maximum of ten computers connected and at least one or more of the computers can also have a printer, scanner or external device which is usable by all the computers on the network.

With a client/server LAN there are multiple computers, one or more servers and additional devices such as printers.The main difference between peer to peer and client/server is that with client/server a network operating system is used to manage storage, connection, security and communications.  This option is more expensive however has the support of the network administration.

Additionally there is the Metropolitan Area Networks (MAN) which allows connectivity between clients in a larger area.  A good example would be multiple office buildings in a larger complex such as a school like UB. 

A Wide Area Network (WAN) is even larger.  This allows connectivity across the country or around the world.  Larger corporations would own a WAN.  Bosch utilizes a WAN and do to the sensitivity and the need for security they have a strict Data Security Policy which is enforced through local "DSP's" (Data Security Partners) who ensure security policies and procedures are are followed strictly. 

This security safety functionality has become a cub business as well http://www.boschindia.com/content/language1/html/17516.htm
