【摘要】：防火墙是为了保护内部网络的安全而设立的第一道防线。防火墙的最根本的目的是防止未被允许的用户进入到内部网络来。在专业的大型网络中防火墙多是以硬件设备设备的形式出现,在小型网络或个人计算机网络中,则可以集成到路由器等设备中,或者可以是一个软件应用程序,防火墙通常被放置在内部网络和外部网络的交界处,对所有传入和传出当前网络的封包进行检测监控,并作出相应的判断和处理。本课题将通过包过滤技术完成一个可以让普通用户方便综合监测控制当前网络状态的个人防火墙。用户可以通过本款防火墙查看当前的网络状态,通过对网络状态和本机的状况来设置网络安全规则控制网络,从而实现网络访问控制、信息过滤等功能,帮助用户抵挡外来网络入侵和黑客攻击,防止本地信息的泄露。本软件采用应用层/核心层双层过滤机制,从而可以完全控制各个网络封包的进出。在防火墙系统的开发过程中,结合采用了结构化和面向对象开发过程的方法,大大提高了系统的开发效率,同时开发过程也更规范。
[Abstract]:A firewall is the first line of defense set up to protect the security of an internal network. The fundamental purpose of a firewall is to prevent unauthorized users from entering the internal network. In professional large networks, firewalls are mostly in the form of hardware devices. In small networks or personal computer networks, they can be integrated into devices such as routers, or they can be software applications. Firewalls are usually placed at the junction of the internal network and the external network to detect and monitor all incoming and outgoing packets of the current network and to make the corresponding judgment and processing. In this paper, a personal firewall which can help ordinary users to monitor and control the current network status is completed by packet filtering technology. Users can view the current network status through this firewall, and set up network security rules to control the network by setting up the network state and the status of the local computer, so as to achieve network access control, information filtering and other functions. Help users to resist external network intrusion and hacker attacks, to prevent the disclosure of local information. This software adopts the application layer / core layer double-layer filter mechanism, thus can completely control each network packet in and out. In the development process of firewall system, the method of structured and object-oriented development process is adopted, which greatly improves the efficiency of system development, and the development process is also more standardized.
