1.0 Introduction

I am hereby to propose a solution to help and maintain the management of ImranEs Corp and

creating a path for a better quality, security and achieving company. For your information, I

have been observed the company for a period and noticed that the administration of network,

services and computerized systems are not properly managed. Thus, I would like to suggest

and provide a tool that can help to manage and reduce these problems. This tool has been sold

in wide area of enterprises and received a very good response from the user. So, I am

guarantee that you will be satisfied using the tool. I will be very pleased if you can approve

this proposal and hopefully I can get immediate response so we can be more efficient in our

work.

2.0 NetDMZ Network Management Software

NetDMZ Network Management Software is a tool that has been suggested for your company

in order to create a great atmosphere in corporate working place. It is designed for local area

network (LAN) monitoring and management software where it can improve effectiveness of

the product and reduce excessive waste of resources.

NetDMZ is open source network software that is applicable for local area network (LAN)

environment. It works under mode of C/S, where the administrator uses a server to monitor

clients within its LAN range.

Windows kernel programming technology is used to monitor and control for this software by

using high-intensity of WYWinStu090. It encoded the communications protocol based on

TCP/IP protocol with web IPR.Foreign-based free open source "winpcap" Ethereal. It is

groups of foreign programmers work for free and they open all the source code. After a little

bit of modification to the software, it would be used as products for sale in the market.

2.1 Features

By using NetDMZ, system administrator can monitor and log any program, applications or

Windows that is currently running or had been run previously through network path for

particular computers. This software especially useful for monitoring and logging files on

employees in a big corporation. They can monitor all client computers within the network

just by through their own office. They can instantly know when their clients visited the

websites, what kind of program running at the moment, what kind of social application (e.g

Yahoo Messenger, MSN, Skype) the clients used and logs their conversation. Besides that,

manager can monitor and logs Windows that clients opened including their screen images,

they plug in the USB in what time, when and what new program that the clients copying,

deleting or installing.

In the software, pie chart is used to show the period of time client have spent on particular

software or program per day and the percentage client use what kind of software or program

for a day. The system administrator can know network traffic of each computer per minute

and identify activity of downloading and uploading files through the server. By this, the

guarantee of companys information security is high.

System administrator can make a file backup in their management system. So, if theres

anything goes wrong with the clients computer, the server still holds the backup data. The

system administration can add or modifying particular work document each day, such as

Word document, to the company server and give a message to a particular client such as

reminder or warning. This software also provides log records of all emails through Outlook to

the server. This is also very important feature since its involves the companys security.

NetDMZ can act as a system information monitor, besides checking the computer hardware

information and hard disk memory usage of the machine.

Besides monitoring, snapshots the clients screen and log reports, the system administrator

can control by blocking certain programs, Windows or websites and make some restriction

for the clients. They can block the USB storage devices andn game intelligently such as Dota,

Call of Duty, Counter Strike and much more; block or restrict the activity of add, remove or

setup programs; after that log reports the blocked programs and Windows. They also can

block any kind of media player such as RealOne, Media Player or Flash show and social

application such as Yahoo Messenger and Skype. They also can filter any website by

blocking or disable search engine for particular websites when the client accessing the

internet such as Facebook, Youtube, porn websites and much more.

System administration also can control the time of client using the computer. For example,

the client can only use the computer during work hour from 8.00 am to 5.00 pm. thecomputer will automatically shut down after pass 5.00 pm. They also can restrict that any

program cannot be open when accessing Word or Excel. The software also provides control

the bandwidth that then client used for downloading and uploading activity or when

accessing websites. By using NetDMZ, the task of monitoring and controlling the clients

becomes much easier and this way could increase the productivity and quality of work of the

company.

3.0 Problem Analysis

Without a system that can control and monitor all activity that involves the company system,

there is a huge risk to the company to a decline not only in economically but also in

reputation and quality work of the employees. For an example, the mislead of using the

internet by the employees for downloading and surfing the internet that do not involved and

related to their work will effect and delay the daily work of company.

Activity such as download video, music, movie and much more will use a huge amount of

bandwidth in the company network and thus will decrease the internet speed and affect the

efficiency of the workers. By surfing the internet or by download file on the internet, there is

a huge risk that a virus will download also in the process and affect the company computer.

This virus could damage the company file, leak it to the internet and also hack into the

company system.When this happen, important document of the company cannot be access

and this can slow down the company efficiency and involve the cost to repair some computer

that has been damage by the virus.

Without any proper monitoring tools, we cant possibly know who and what the employees

are doing. Also in sending or receiving email, we cannot trace who and what type of

messages is being sent. It might be a threat of the security of your company, and they will no

backup of the email service. We can control, analysis, monitor and make sure the above

problem would not happen with the use of NetDMZ system that can control almost every

activity in the company computer and system.

4.0 Conclusion

NetDMZ system along with its various features helps to increase the quality of our network

and computerized system will be more manageable and secure. By implementing the system,

it will reduce the worry of the company about leakage important or secret information

regarding the company and its product and increase the security system. It will also managing

and secure the companys finance, file management, employee carelessness and much more.

Company will gain lot of benefit from it, not for a while but for a long term. It is better to

prevent the problems from happening rather than to fix it which increase money consumption

and delay time.

HOW TO INSTALL,DEPLOY AND CONFIGURE

Guide of installation

The NetDMZ program is split into two parts that is for the client and for the server. The client

is installing to the worker and the server is installing to the system administrator.

For the client installation, the setup will ask the name of the computer or the IP address of the

server. This will help the server to detect the client computer.

Guide for using NetDMZ

This is the main interface for the server installation setup. From the screenshot above, the

server is monitoring the computer name DARK-PC. This monitoring system can get the IP

address and MAC address of the computer.

When the server double clicks a certain computer, there are several option available for the

system administrator such as limit option, browser, client and much more. NetDMZ can

block process, program, installation of a device, instant messaging and much more. This will

help to avoid the worker to do something unnecessarily that is not related to the work.

This open source program also provides service of blocking any URL that has been choose

by the system administrator. This block URL cant be open by the client in any way. Some

program such as Internet Explorer and Mozilla Firefox can also be block by using this option.

The system administrator also can decide what word that the client cant see. In this

screenshot, any website that contains the word stock or lottery cant be view by the client

in any way of possible. There are also some options to allow the URL that contain those word

to be view. This can be done by adding the URL itself to the exception list.

Some programs can be blocked from the server itself. Program with extension such as exe,

mp3, doc and much more can be block. These blocked programs cant be run at the client

computer unless it is allowed by the system administrator itself.

10

Each of the computer is set to save a log file that will record every activity of the computer

such as data transmission, URL visited, instant messaging, Email from Outlook, Programs

that ran and screenshot setting.

An advantage of this software is it can backup any type of document such as office document,

music and much more from a specific computer or group choose by the system administrator.

Those file will be automatically upload to the server from the client and the server will store

it. These will help decrease of lost of important data in a company.

The main problem in most of the company is the bandwidth allocation for each of the

computer. When a computer downloads a huge file at a time, it will affect the other computer

in the same with network. NetDMZ provide bandwidth limitation to computers. The

download and upload speed of a computer is fixed so that when it download or upload, it

wont affect the other computer in same network.

NetDMZ give the privileges to the system administrator to block certain port of a computer

remotely such as port number 1513 for online gaming programs and port 8080 for internet

surfing that is commonly used for web proxy and caching server, or for running a web server

as non-root user.

There are some issues in most of the company in the world such as worker do work overtime

but not exactly do their work. An option is provided to the server installation that allow the

server to disable, block, shutdown or customize a client computer after a certain period of

time that is decided by the company policy.

NetDMZ will detect automatically detect each and every software from the start of

monitoring the computer until it shutdown. Every activity, open application, running process

and much more will be shown to the system administrator.

The system administrator can send a simple message to the client computer and the client

computer will receive the message. This is very useful to warn the worker to do things relater

to work only and not doing anything else. The server computer can remotely shutdown or

restart the client computer without asking the client permission.

The client computer will receive the message from the server computer and the client cant

reply it back.


15/17

Server computer will automaticly capture the image of the desktop that is set by the system

administrator. This is as a proof if the worker is doing something other work when in

working time.

The above screenshot, there are several option that is given to the system administrator in

order to control a particular computer or group. This options include viewing the program

that has been installed in a computer, view the running process, system information such as

hard disk space and RAM of the computer. The administrator can also restart the computer or

turn off the computer without warning to the client itself. This can help the systemadministrator to shutting down computers without going to each of the computers.

NetDMZ is mainly to assist the network administrator in monitoring other computers

in order to prevent the worker wasting their time on web surfing the internet, gaming,

streaming and downloading rather than doing their work.

Most of the workers nowadays is always surfing the internet such as Facebook, twitter,

Myspace and Friendster even when it is in the working hour. This would decrease the

efficiency of company and thus slowing down the productivity of a company. With the used

of NetDMZ, the system administrator can prevent this from happening by blocking a certain

URL or words in a website. The blocking service is also include on blocking application

inside the client itself such as music, games, block access to control panel, regedit and much

more that is depend on the system administrator to set it.

Another common problem that is always happen is the used of bandwidth inside the

company itself. Bandwidth is shared among the computers inside the company. When a

certain computer download or upload a huge file from the internet, it will affect the other

computer in the same network thus slowing the other computer in doing their work. This

problem can be prevent by limiting the bandwidth in each group or computer so that it wont

affect the other computer in the network (LAN).

There is a possibility that any of the computer inside the company network might be

infected by virus such as malware, Trojan and spyware that could lead to file lost or

corrupted windows file. The system administrator can setup a time for any computer to send a

backup to the server. This could prevent data lost and consumption of time for recovering the

file again.

With the used of NetDMZ, the network administrator can remotely shutdown or

restart any particular computer inside the organization without going to each of the computer.

This will be a huge safe of time for shutting down computers after the working hour because

there might be some worker that not turning their computer off.

This application also can save every log that has been done on the client computer

such as instant messaging log including yahoo messenger, Skype and much more. The

change of hardware is also recorded to prevent unnecessarily hardware install to the computer.

Every bandwidth that used on the computer will be recorded.

Another option added to the software is the backup of email in Microsoft Outlook.

Microsoft Outlook is mainly used for storing email from yahoo server. In any case if the

client computer broke down, a backup of the document will be sent to the server with the

time set by the server. This will help decrease data loss in the company and save time by

preventing recovering the data. NetDMZ also help the system administrator to monitor every

activity of the client computer to prevent mislead of using the company computer according

to the company IT policy.
