计算机网络技术的迅猛发展,为企业共享全球范围内的信息和资源提供了方便,有效降低了企业的运营成本并改变了传统的工作模式。随着企业内部网络的日益庞大及与外部网络联系的逐渐增多,传统的集中式、静态网络安全体系已经不能满足需要,一个安全可信的企业网络安全系统显得十分重要。为了解决打叶企业在信息化建设中面临的网络信息安全问题,在充分研究网络安全需求的基础上,通过分析现今防火墙技术的分类及各种类型防火墙的优缺点,为企业在构建防火墙时对防火墙的选择与设置问题提出建议。制定相应安全策略,并采用相应的安全技术手段来加以实现。
The rapid development of computer network technology provides enterprises with convenient access to worldwide information and resources, effectively reduces the operating costs of enterprises and changes the traditional working mode. With the increasingly large internal network and the increasing connection with external networks, the traditional centralized and static network security system can not meet the need. A secure and trusted enterprise network security system is very important. In order to solve the problem of network information security faced by enterprises in information construction, this paper analyzes the current firewall technology classification and advantages and disadvantages of various types of firewall on the basis of fully studying the network security requirements, Firewall selection and setting issues to make recommendations. Develop the appropriate security strategy, and adopt the appropriate safety technology to be achieved.
