摘要：伴随着智能终端设备的不断普及以及各大运营商的宽带大提速，无线已经成为家庭组网的首选，越来越多的公司单位以及个人用户开始使用无线路由器，来在局部范围部署无线网络。然而，无线路由器应用愈加广泛、与我们的生活联系愈加密切的同时，安全问题也日渐凸显出来，无线路由器常常会因为固件BUG、设置错误、系统漏洞等因素，引起一些安全问题，要是这些问题被恶意用户利用，便很有可能会造成无线路由器被非法攻击，出现如网银被盗、隐私暴露、数据丢失等问题。甚至这些恶意用户可以通过入侵的无线路由器，威胁整个无线网络的运行安全。无线路由器的安全问题现在还处于启蒙发展阶段，但是它的重要性却是不言而喻的。现在网上论坛经常爆出各种各样的漏洞，正是由于我们对无线路由器安全缺乏重视，才导致安全问题频频发生。当然我们在研究过程中，必须要保证在不侵害他人信息安全的前提下进行，绝对要杜绝利用他人的信息安全来进行我们的实验测试。本论文以斐讯PSG718为研究对象，该路由器是一个智能无线双频路由器，可以同时发射长波和短波两种无线AP信号，既可以进行短距离强力穿透障碍物的无线覆盖，又可以在无阻碍的情况下进行大范围的无线覆盖。本路由器几乎包含了所有家用无线路由器需要的功能，非常适合作为本次论文的研究对象。通过对路由器内部的配置研究调试，对现有漏洞的问题进行分析以及开展系列的漏洞测试和加固，更好地去发觉新的安全漏洞，同时我们还将自主编程对路由器进行小测试，这些测试包含对该路由器的攻击以及安全性测试。在平常生活中，我们会由于没有对路由器进行安全配置，从而导致漏洞被利用，而发生各种安全隐患。为了避免此类事情，本文也将对我们平常路由器的配置操作进行研究，用以改善我们平常生活中大部分人对于路由不会安全配置的事情。77509

Security Detection and Reinforcement Design Of Wireless Router

Abstract: With the popularity of intelligent terminal equipment and the improvement of broadband speed of the operators, wireless has become the first choice for home networking。 More and more users began to use wireless routers to deploy wireless networks in the local scope。 However, the security issues are increasingly highlighting when wireless routers are used widely day by day and closely linked to our lives。 Wireless routers often cause some security problems because of firmware bugs, wrong settings, system vulnerabilities and other factors。 If these problems were used by malicious users, it is likely to cause illegal attacks to the wireless routers, such as information leak of the online bank account, privacy exposure, data loss and other issues。 Through these wireless routers which were been invaded, the malicious users can even threaten the operation of the entire wireless network。 The security settings of wireless routers are still in the stage of development, but its importance is self-evident。 Now online forums often point out a variety of vulnerabilities, it is because of our lack of attention to the safety of wireless routers which led to frequent security problems。 Certainly, we must on the premise of ensuring that do not infringe others’ information security during the research process, and we need absolutely put an end to the use of other people's information security to carry out our experimental test。 This paper is based on the research of Phicomm PSG718, which is an intelligent wireless dual-band router。 It can transmit two kinds of wireless AP signals at the same time: long wave and short wave。 Not only can PSG718 carry out wireless coverage in short range and with strong penetration through the obstacles, but also achieve a wide range of wireless coverage in the case of without obstacles。 This router contains almost all the functions that a home wireless router needed, and it is very suitable for being a research object of this paper。 Through the research and internal debugging of the router configuration, the analysis of existing vulnerabilities, and series of vulnerability testing and reinforcement, it is better for us to find new security vulnerabilities。 And we will also program the router for some small tests which include attacks on the router and security testing。 In daily life, we will face various security risks due to the lack of security configurations of the router which was caused by vulnerabilities。 In order to avoid such things, this thesis will also study the configuration of our common routers to improve the situation that in our daily life most people cannot finish the security configuration of the routers。
