中小型企业网络安全规划设计与实施

校园网或企业网网络安全方案设计和实现的文档

摘要

随着计算机技术突飞猛进的发展，互联网的应用也越来越广泛，在网络环境下运行的各种应用系统越来越多，通过网络传输的各种信息也在不断增加。从目前中小型企业计算机技术的应用情况来看也是如此，目前中小型企业已经建立了企业网站，电子邮件等系统，并且已经实施了ERP、电子商务、IJR等信息系统，许多重要信息都存储在网络服务器中，因此网络系统的安全至关重要。这就要求我们对安全问题进行深入分析研究，在整个中小型企业建立多层次的网络安全体系。

本文立足于中小型企业网络安全的规划设计与实施，对中小型企业网络系统方面存在的安全问题进行了深入分析，针对这些问题给出了总体解决方案并在中小型企业内进行了实施。

通过中小型企业网络安全的规划设计和实施，提高了中小型企业网络系统的安全性和稳定性。同时随着计算机技术的不断发展，对网络系统的安全性提出了更高的要求，因此中小型企业会根据网络系统不断发展的要求，进一步规划设计出更加适合中小型企业发展的网络安全系统，满足中小型企业信息化建设不断发展的要求。

Abstract

With the rapid development of the computer technology, the Internet is more and more widely, more and more application systems running in network environment, through a variety of information network transmission is also increasing. The application of computer technology in small and medium-sized enterprises at present is so, the small and medium-sized enterprises have established enterprise website, email system, and have implemented ERP, e-commerce, IJR and other information systems, many important information are stored in the network server, so the security of network system. This requires us to study on security issues, the establishment of network security in the multi-level system of small and medium enterprises.

Planning design and Implementation Based on the small and medium-sized enterprise network security, security problems of the small and medium-sized enterprise network system are analyzed, in order to solve these problems are given the general solution and in the small and medium-sized enterprises in the implementation of.

Through the planning design and implementation of small and medium-sized enterprise network security, improve the small and medium-sized enterprise network system security and stability. At the same time, with the continuous development of computer technology, put forward higher requirements on the security of the network system, so small and medium-sized enterprises will be based on the development of the network system, further planning and design of network security system is more suitable for the development of small and medium enterprises, informatization of small and medium enterprises to meet the demand of the development of.
