The harm of worms' outbreak becomes greater and greater. Such make worm detection and defense technology face an increasingly tough challenge. Attack Signature Automatically Generation technology is one of the key technologies, this paper focuses on the ASAG technology for research, its main jobs include: 1）Analyzed the research status of ASAG technology from the overall, described its design goals and evaluation criteria, and the current approaches' limitations is given. 2） After deeply researching and analyzing a various of ASAG systems, a basic framework for the network ASAG system is presented, and the detailed analysis of the main function of the components in the framework is also presented. 3）An attack capture model based on distributed honey-pots system is presented. This mode integrates the anomaly detection which based on the mode of dubiety score in the honey-pots, can do a second filter for the samples in honey-pots, and improve the purity of the samples captured. 4） A simple noise-resilience ASAG algorithm is presented, which used the behavioral characteristics of the worm outbreak to generate efficient signatures of samples in the suspicious dataset, which contains large amounts of noisy data, under the complex environment.

攻击特征自动提取技术是网络蠕虫防御技术的关键技术，本文围绕攻击特征自动提取技术开展研究工作，其主要工作包括： 1）对攻击特征自动提取技术的研究现状进行了综述，介绍其设计目标与评价标准，并指出了现有方法存在的局限性； 2）在深入研究与分析各种攻击特征提取系统的基础上，提出基于网络的攻击特征自动提取系统的基本框架，并详细分析框架中各部件的主要功能； 3）提出了基于分布式蜜罐系统的攻击样本捕获模型，该模型在分布式蜜罐系统的基础上，结合基于可疑度模型的异常检测，对蜜罐中的样本进行二次过滤，较好地提高了捕获样本的纯净度； 4）提出一种简单抗噪的攻击特征自动提取算法，该算法利用蠕虫爆发时的行为特征，在复杂环境下含有大量噪声数据的可疑样本训练集中提取有效的特征，降低对样本纯净度的依赖。
