防火墙技术研究报告 防火墙技术 摘要：随着计算机的飞速发展以及网络技术的普遍应用，随着信息时代的来临，信息作为一种重要的资源正得到了人们的重视与应用。因特网是一个发展非常活跃的领域，可能会受到黑客的非法攻击，所以在任何情况下，对于各种事故，无意或有意的破坏，保护数据及其传送、处理都是非常必要的。比如，计划如何保护你的局域网免受因特网攻击带来的危害时，首先要考虑的是防火墙。防火墙的核心思想是在不安全的网际网环境中构造一个相对安全的子网环境。文介绍了防火墙技术的基本概念、原理、应用现状和发展趋势。 Abstract: along with the universal application of the rapid development of computer and network technology, with the advent of the information age, information as an important resource is paid attention to and used by people. The Internet is a development of very active domain, may be illegally attacked by hackers, so in any case, for a variety of accident, accidental or intentional damage, protection of data and transfer, processing is very necessary. For example, plans to protect your network from the hazards brought by Internet attack, firewall is the first consideration. The core idea of firewall is the relative safety of the structure of a network environment in the insecure Internet environment. This paper introduces the basic concept of firewall technology, principle, application status and development trend.
