摘要

在科学技术日新月异的今天，计算机已逐步渗入各个领域，随着网络的发展使我们进入了信息化时代，与此同时我们决不能忽略安全问题。尤其是校园网络安全问题更令我们头疼。为了解决这个问题，我们必须注重安全问题及应对的策略，校园网络安全管理是在防病毒软件、防火墙或智能网关等构成的防御体系下，对于防止来自校园网外的攻击。防火墙，则是内外网之间一道牢固的安全屏障。安全管理是保证网络安全的基础，安全技术是配合安全管理的辅助措施。学校建立了一套校园网络安全系统是必要的。

本文从对校园网的现状分析了可能面临的威胁，从计算机的安全策略找出解决方案既用校园网络安全管理加防火墙加设计的校园网络安全系统。通过以下三个步骤来完成校园网络安全系统：建设规划、技术支持、组建方案。

关键词：网络 安全 设计

Abstract

In science and technology are developing rapidly today, the computer has gradually

into every field, along with the development of the network into the information times, and at the same time we must not ignore safety problems. Especially the campus network security issues more make us a headache. In order to solve this problem, we must pay attention to safety problems and deal with strategy, campus network security management is the anti-virus software and a firewall or intelligent gateway of defense system, to prevent from outside the campus network attack. Firewall, is between inside and outside a strong safety net barrier. The safety management of network security is based, safety technology is the auxiliary measures with safety management. The school has established a set of campus network security system is necessary.

This paper, from the analysis of the status of the campus network may be threatened, from the computer security strategy find solutions with both campus network security management and firewall and design of the campus network security system. Through the following three steps to complete the campus network security system: construction planning, the technical support, the construction scheme.

Keywords: Network Security Design
