Alongside the respect an administrator owes users of his or her server, the admin also must respect the rights of other administrators and their users. One way in which an admin must do so is by conserving bandwidth. Bandwidth is the amount of information that can be conveyed through the network.
Some services require or use a lot of bandwidth.
Specifically, a file server or web server with popular software may monopolize bandwidth. This a is violation of others rights to use the network, and should be avoided. These machines have only one user, that being the owner sitting in front of them. The users of these computers deserve equal access to bandwidth and network resources. Because a server provides services to not only the administrator but the client users as well, the server admin has a heightened need for security on the machine.
