基于防火墙技术的网络安全系统模型构建

摘要

Firewall, as an effective network security mechanism, is able to protect company internal networks from external malicious attacks. Based on the technology,the paper designed a program for a network security model by taking Company M as the research object,which will ensure that only authorized legal data can be transmitted within the companyˊs network.%防火墙作为一种有效的网络安全防护措施，能够防止企业网络受到外界入侵者的恶意攻击。为此以M企业为研究对象，基于防火墙技术提出了网络安全模型构建方案，可以确保只有被授权的合法信息流才能在企业网络中进行传输。
