入侵检测技术是保证网络安全的重要内容,然而现有的入侵检测系统还存在一定的缺陷和漏洞,比如对于大规模信息攻击还束手无策等。移动代理技动态灵活性,以及云计算技术较强的存储能力和计算能力,可有效应对大规模信息攻击,对网络安全技术发展有重要意义。因此,本文基于云计算技术和移动代理技术,设计出云计算环境下联合移动代理技术的入侵检测系统,借助NS2应用软件对传统网络环境下和云计算环境下联合移动代理技术的DDo S节点入侵进行模拟实验,并以攻击强度为变量多次实验,得出云计算环境下联合移动代理技术的入侵检测系统对大规模信息入侵的预防有明显作用的结论。
Intrusion detection technology is an important part of ensuring network security. However, existing intrusion detection systems still have some flaws and flaws, such as being helpless for large-scale information attacks. The dynamic agility of mobile agent technologies and the strong storage and computing power of cloud computing technology can effectively deal with large-scale information attacks and are of great significance to the development of network security technologies. Therefore, based on the cloud computing technology and mobile agent technology, this paper designs a joint intrusion detection system based on mobile agent technology in the cloud computing environment. By using the NS2 application software to invade the DDoS node in the traditional network environment and the joint mobile agent technology under the cloud computing environment Simulation experiments are carried out. Taking the attack strength as a variable, many experiments are carried out to conclude that intrusion detection system based on the combined mobile agent technology in cloud computing environment has a significant effect on the prevention of large-scale information intrusion.
