【摘要】：如今智能手机越来越普及,功能也变得逐渐强大起来,传统的互联网已经远远满足不了现代人们对于网络的实时需求了,除了在家里或者在办公室以外,人们更多的时间是通过智能手机来访问移动互联网,人们在享受移动互联网带来便捷的同时,也不能忽略其伴随而来的安全问题。手机病毒层出不穷,让使用智能手机的用户饱受其苦,手机作为人们的贴身物品,里面有很多的个人隐私信息,一旦被病毒入侵,后果将不堪设想。针对这一现状,本论文研究并设计了基于智能手机的入侵检测系统来提高智能手机防御入侵的能力。入侵检测是在防火墙之后对网络安全的进一步把关,在传统互联网领域已经发展得较为成熟了,但是在移动互联网领域的研究却才刚刚起步。本论文首先分析了移动互联网的安全问题,其中数Android智能手机面临的安全问题最为严重。接着介绍了入侵检测技术的相关知识,为研究基于智能手机的入侵检测系统打好理论基础。然后针对该系统中需要用到的关键技术做了详细研究,数据包捕获技术、模式匹配技术、协议分析技术,考虑到手机的特性,本文决定将模式匹配技术和协议分析技术结合起来进行入侵攻击的检测。之后还加入了行为检测方法检测未知的入侵攻击。最后在Android平台上对系统进行了实现和模拟,结果表明基于智能手机的入侵检测系统能及时有效的检测到入侵攻击,有较好的识别入侵攻击并向用户发出告警的功能,可以大大改善用户的体验。
[Abstract]:Nowadays, smartphones are becoming more and more popular and functions are becoming more and more powerful. The traditional Internet is no longer able to meet the real-time needs of modern people, except at home or in the office. People more time to access the mobile Internet through smartphones, people enjoy the convenience of mobile Internet, but also can not ignore its accompanying security problems. Mobile phone viruses emerge in endlessly. Let smartphone users suffer, mobile phone as a close object, there is a lot of personal privacy information, once the virus invasion, the consequences will be unthinkable. In view of this status quo. This paper studies and designs an intrusion detection system based on smart phone to improve the capability of smart phone intrusion prevention. Intrusion detection is a further check on network security behind the firewall. In the field of traditional Internet has been developed more mature, but in the field of mobile Internet has just started. Firstly, this paper analyzes the security of mobile Internet. Among them, several Android smart phones face the most serious security problems. Then, the related knowledge of intrusion detection technology is introduced. In order to study the intrusion detection system based on smart phone, it lays a good theoretical foundation. Then, the key technologies used in the system are studied in detail, such as packet capture technology, pattern matching technology, protocol analysis technology. Considering the nature of the phone. This paper decides to combine pattern matching technology with protocol analysis technology to detect intrusion attack, and then adds behavior detection method to detect unknown intrusion attack. Finally, the system is tested on Android platform. Implementation and simulation are carried out. The results show that the intrusion detection system based on smart phone can detect intrusion attack in time and effectively, and has the function of recognizing intrusion attack and sending out alarm to user, which can greatly improve the user's experience.
