NETWORK AND SYSTEM ADMINISTRATION
1. Introduction
The report is prepared for the development of a computer network system for
connecting the head office of the organization with its branches. A simple peer to peer
network is used for the connection and sharing data and resources. The current setup of the
organization is evaluated for the development of the network framework. The number of
devices connected in the network is estimated for the development of IP addressing plan and
a network diagram is created demonstrating the topology and devices used for the
management of interconnection. A security plan is created for centrally administering the
network and the performance metrics and the hardware setup is demonstrated in the report
that would help to setup the system.
2. Requirement Gathering
For the development of the network solution it is important to gather the requirement
and create a network design aligning the requirement. The users of the network is needed to
be divided into groups for enabling sharing of data and resources. Privileges are needed to be
managed for providing them different services and improving communication, collaboration
and threat protection. According to the requirement a hardware is needed to be setup and it is
needed to be installed and configured with the DNS, DHCP, HTTP and client OS setup such
that a centralized user management is enabled. The number of subnets needed and the
number of hosts needed to be connected per subnet is need to be identified. The services that
are needed by the user for management of internal communication is also needed to be
evaluated for the configuration of the server with the service and align the network following
the requirement. A firewall is needed to be deployed for restricting the outside user to access
the internal resources of the organization and a VPN connection is also needed to be setup
between the branches for increasing the security of the network framework.
