Network security becomes increasingly important because there are number of users in offices, cafe, a housing complex began to connect the computer to its network using operational channel which online in 24 hours at high speed using DSL or wireless technology 2 -11 Mbps. Of course, the computer or the client is generally use static IP addresses. This situation may caused some irresponsible person such as cracker can do interrupt the network (although some are just for fun only) it is very dangerous for network.

1.2. Objective

Hopefully all of us can understand and know how to use or Soft perfect Personal Firewall in your network to resolve many networking security problems.

1.3. Problem Definition

We just explain what are Soft perfect Personal Firewall, how it works, features of it and the implementation and benefit of this technology.

1.4. Writing Structure

In this paper, we will divide become four Chapter. We will formulate to become three chapters so that the readers more understand. There is:

About The Application

Soft perfect Personal Firewall is a free network firewall designed to protect that your PC from attacks from the Internet or local network. Soft Perfect Personal Firewall offers something that is able to secure with the rules (user-defined) for filtering packets. It works on a low level and also allows you to create rules based on non-IP protocols such as ARP. SoftPerfect Personal Firewall supports various forms of network adjustments. It allows you to apply a rule, for example, only for modem connection or you could apply separate rules for the system tool of others.

Problem Analysis

3.1. Problem Statement

Currently, many programs (tools) that can be used to do the scanning process in many computers in the Internet network. With the rapid connection to the Internet and many web sites that provide a tool which can be used to perform scanning & attack actually some users can scan 1000 computers in a day to see a variety of simple and configuration error. A cracker can scan a 1000 PC to less than one hour and not impossible to find 2-3 weak PC that can be pierced. Indeed, most of the servers on the Internet are set with a very high security. But the network is in the homes & offices generally use a simple setup that is very friendly & open to the Internet, this type into the soft target of the cracker

So we need to install security software to prevent this kind of threat, for the example we can use Soft perfect Personal Firewall. This software has many function and features in auditing monitoring network so we can prevent many threats in we run this software in our PC. .

3.2. How to Implement The Application

Getting Started Using Soft Perfect Personal Firewall

After installing Soft Perfect Personal Firewall, restart the computer. After the system started, a window will appear requesting your firewall predestinate rules. Rules that have been recognized include browsing the WWW, E-Mail, and others. Rules ARP, ICMP, and DNS are set prior to the network operating properly.

2) Filter communications

3) Text Box: Block all communication

If there are no rules for the communication package and the package is disabled it will prohibit the communications.

The main window as indicated below:

Windows in left use for access the information network equipment, rules and firewall events log. Use the toolbar to access various special programs. In the right window displays more information about anything you choose. In this case, a list of rules is shown. Rules are applied in the order that has been set.

At the source and destination protocol is the active protocol only as a basis for IP such as TCP, UDP and ICMP. They will allow defining the source and destination addresses and package and / or destination port.

In Advance window is use to set additional settings process for ICMP and other variations. Note, if the message is always the goal is not reached across the firewall to the other way in down the ability of the network.

Trusted MAC Address Management

Text Box: If the local network or on the local network wireless can only communicate with the workstation and server that can then be trusted, we can set the hardware addresses (MAC addresses) here. This firewall instruction to deny traffic from anywhere except from trusted address that you have set and make power on a certain type of attack such as ARP-spoofing.

Learning Mode

Firewall learning mode in order to help defining rules quickly and easily. For example, if you have not found the rules, learning mode can help you to define rules, for example when trying to open a web-site will be visible to a firewall like this:

Text Box:
