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。

It is the change that virtual technology gives birth to a great influence on the human's cognitive activities. First of all, virtual technology has caused obvious change of cognitive relation between subject and object, which includes the change of interaction between subject and object, digitization of cognitive resonance and scene of cognitive model, etc. secondly, virtual technology has improved the subject's cognitive ability and level: the ability of esthesia of the subject has been strengthened, the change of the cognitive structure and the way to obtain information of the subject has been caused and the regulation and control ability of the subject has been improved by virtual technology.

正是这种转向使得虚拟技术对于人类的认识活动产生了重大影响：首先，虚拟技术导致了主客体之间的认识关系发生明显的变化，主要包括主客体作用的方式的变化、认识中介的数字化以及认知模型的情景化等；虚拟技术提高了主体认识能力和水平：虚拟技术增强了主体的感知能力，引起了主体认识结构的变化，认识主体获取信息的方式发生了变革，提高了主体对认识活动的调控能力，张扬了主体在认识活动中的能动性与创造性；虚拟技术拓展了主体的认识领域，即它扩展了主体的认识空间、丰富了主体的认识来源。
