随着社会经济的不断发展,网络信息技术也在不断进步,但在网络使用过程中,各种问题接连出现,且问题导致的损失是比较大的。为了解决这些网络信息安全问题,相关技术人员发明了网络防火墙,它是一种常见的网络安全设备,近年来,还增加了网络运行状态检测、虚拟局域网等重要功能,可以实现网络信息的有效传输,传输速度是非常快的,检测成本和费用也是比较低的,保护功能是比较大的,在网络当中的应用范围十分广泛。要想起到良好的保护作用,包过滤防火墙管理技术和技术管理效率高低是非常重要的,同时包过滤防火墙管理技术的要点也是比较多的,管理规则也是比较复杂的,如果包过滤防火墙管理不到位或者技术落后的话,就会出现网络安全漏洞、引发网络安全风险。
With the continuous development of social economy, network information technology is also making continuous progress. However, various problems occur one after another during the course of network usage, and the losses caused by the problems are relatively large. In order to solve these network information security problems, related technical personnel invented the network firewall, which is a common network security device. In recent years, it has also added important functions such as network operation status detection and virtual local area network, and can effectively transmit network information , The transmission speed is very fast, detection costs and costs are relatively low, the protection function is relatively large, in the network which is widely used. In order to play a good protective role, packet filtering firewall management techniques and technical management efficiency is very important, and packet filtering firewall management techniques are also more points, the management rules are more complex, if the packet filtering firewall management is not in place Or backward technology, there will be loopholes in the network security, lead to network security risks.
