Networking - Research Paper Example

Computer networking School Introduction Big companies need to have a network that connects the entire company with its workers and the surrounding environment in which it exist. It is important for the company to establish a secure connection especially where by the company has various departments which are stationed in different locations, for our scenario, Lucerne Publishing company has cooperate offices which requires interaction through network access where workers need to access the services remotely in order to increase the labor force size.

In order to allow remote connection by the workers one need to upgrade the internet connection by first having a domain established so as to allow a VPN connection. The VPN allows users to connect to the network system through a remote connection system. This is done by configuring in a server to enable client computers to connect to the network. Due to the fact that remote access to clients does not support routing protocols such as the routing information protocol, the client user uses a simple routing table with remote packet from remote users to the internet and the intranet connection or simultaneous and thus depends with the user.

For example a user on a LAN has a route to its own subnet in the LAN and thus having a default gateway router for all the traffic and thus without the remote access, user cannot determine the best route to its destination. The best method to route traffic in this network is by directing packets through a remote network to a remote network. Routing By default, when a connection is established, the remote client access inserts a default route in its respective routing table and hence increases the size of the default gateway route to ensure that the newest route is used and thus will ensure that every client computer on the network communicates with its route to avoid collision and loss of energy.

The new rout connection to its route point ensures none of the data packets are not addressed in the LAN system on the remote network. Under this type of configuration, as a result of the VPN client connection, is creation of a new route and thus enhance more data security. Based on the default route added, all the users will have a broad access to the internet or on the company’s intranet. Window servers 2008 In order to configure the window server 2008 as a router you need to have the following essentials (Bender, 2010).

An internet connection for a stable internet service provider and a digital service line (DSL) modem which is a modem and a broadband router, a router which routes traffic from the local network to the internet, clients computers which connects to the main frame computer to form a network system, these are the computers that the users will use, and the windows 2008 sever essentials that will provide file sharing and used for remote access. The router will be configured such that it allows only assigned IP address to connect to the network system for improved security in the network. Fig 1.1 Windows server as a router Security In remote access network it is very vital to observe security measures in the virtual private network to prevent the treats in the organization network system.

This measures includes the use of company owned computes that are well maintained and serviced with anti-malware soft wares by the company’s IT department and are configured in the network systems such as the domain system. Restrict the authorization of installation of UN authorized software’s, this is done to protect the company’s computers against malicious software, this is done through the use of standard user access accounts in the company computers. Educate the interactive remote users on the need to use anti malwares to protect the company’s data.

Use of firewall and proxies, firewalls and proxies restricts users from accessing unauthorized sites that might contain malicious content to protect the company’s data and the network system. The use of the active directory to manage the users who are using the network system, the active directory can be used to restrict illegal access to the network and also to lock users who enter wrong authentication information in the system to prevent fraud and impersonation by the use of access control.

Data base optimization The SQL server database can be optimized by clustering the data block into distinct orders that match the indexes which results is the storage of raw data (Millsap & Holt, 2003). Therefore, only a single index can be created in a database table which greatly increases the retrieval speed usually sequential data access in the reverse order. References Bender, M. (2010).
