计算机网络安全策略

计算机网络安全策略摘要计算机网络是一种利用通信网络进行信息传递的系统，主要是指通过一个或多个信息处理中心（称为主机）来完成信息传递。它可以处理和控制各种类型的数据，包括文字、数据、图像等多媒体数据。在计算机网络中，主要用于传递和处理两个方面：一是传递各种计算机软件程序和硬件设备的指令：二是控制主机的某些功能，如读写硬盘、进行网络连接等。为了使计算机能在广域网上正常运行，必须使其与网络相连。网络的安全性对于计算机网络来说是至关重要的。随着计算机技术的飞速发展，计算机网络在人们社会生活中发挥着越来越重要的作用，已经成为一个国家信息化建设的基础，是经济和社会发展的重要标志之一，它已渗透到社会生产、生活以及科学技术的各个领域中，成为现代信息社会不可缺少的重要基础设施。在当今世界政治经济形势下，信息技术更成为各国各领域关注和竞争的焦点。为了提高综合国力、增强竞争力、掌握和发展新一代信息技术，在国际范围内大力推进信息基础设施建设已成为世界各国政府和产业界共同关注的重要议题。随着互联网及多媒体技术的迅速发展，互联网已经从一个简单的资源共享平台演变成为一个功能复杂、服务广泛、开放灵活、资源丰富、内容繁多、应用广泛和具有巨大商业潜力和价值的网络。从互联网诞生之日起，它就面临着各种各样安全问题。由于网络具有开放性、自治性等特点，所以使得网络攻击和破坏变得更为容易，其安全隐患也更为突出。关键词：计算机网络：信息安全：黑客：网络入侵AbstractComputer network is a system that uses communication networks for informationtransmission,mainly refers to the completion of information transmission through one or moreinformation processing centers (called hosts).It can process and control various types of data,including multimedia data such as text,data,images,etc.In computer networks,it is mainly usedto transmit and process two aspects:one is to transmit instructions for various computer softwareprograms and hardware devices;The second is to control some functions of the host,such asreading and writing hard disks,network connections,etc.In order for a computer to functionproperly on a wide area network,it must be connected to the network.The security of thenetwork is crucial for computer networks.With the rapid development of computer technology,computer networks play an increasingly important role in people's social life,have become thefoundation of a country's information construction,is one of the important symbols of economicand social development,it has penetrated into social production,life and science and technologyin various fields,has become an indispensable important infrastructure of modern informationsociety.In today's world political and economic situation,information technology has becomethe focus of attention and competition in various fields of various countries.In order to improvecomprehensive national strength,enhance competitiveness,master and develop a new generationof information technology,vigorously promoting the construction of information infrastructureon an international scale has become an important issue of common concern to governments andindustries around the world.With the rapid development of the Internet and multimediatechnology,the Internet has evolved from a simple resource sharing platform to a network withcomplex functions,wide range of services,open and flexible,rich resources,rich content,wideapplication and huge business potential and value.Since its inception,the Internet has faced avariety of security issues.Because the network has the characteristics of openness and autonomy,it makes it easier to attack and sabotage the network,and its security risks are more prominent.Key Words:Network;Information security;Hacker;Network intrusion
