近年来,随着金融电子化程度的不断提高,各银行纷纷组建起各自的计算机网络。在金融网络中,资金安全与系统的安全是最使人关注的核心问题。当前,针对金融系统的犯罪,尤其是攻击金融计算机网络犯罪的行为正在逐年增加。如何对此进行有效的防范,是我们面临的一个重要课题。 金融计算机网络中普遍采用的安全措施是口令控制、权限限制和信息加密传输等方法,但在网络互连日益普及的今天,这是远远不够的,迫切需要有一种能够有效地防范外部网络侵入的技术,以保证系统和数据的安全。目前,一种使用很广泛的网络安全技术就是防火墙技术(Firewall),即在Internet和内部网络之间设立一个防火墙。由于金融网络互连的基础与Internet一样均是TCP/IP,因此,防火墙技术同样适用于金融计算机网络。
In recent years, with the continuous improvement of the financial electronic level, banks have set up their own computer networks one after another. In the financial network, financial security and system security are the most concern. At present, the crimes against the financial system, especially those that attack financial computer networks are increasing year by year. How to effectively prevent this is an important issue we face. Commonly used security measures in financial computer networks are password control, permission restrictions, and information encryption transmission. However, today’s network interconnection is increasingly widespread, which is not enough. There is an urgent need to effectively prevent external network intrusion Technology to ensure system and data security. Currently, a widely used network security technology is the firewall technology (Firewall), that is, set up a firewall between the Internet and the internal network. As the foundation for financial network interconnection is TCP / IP, just like the Internet, firewall technology is equally applicable to financial computer networks.
