According to using easy company network safe expert introduces: According to the frangibility of Web application process that OWASP organization released 2007 the statistical result of 10 big ranks makes clear, the flaw of the script that cross a station, infuse, request that cross a station is forged, information divulges the problem that waits for a respect to remain the hacker's at present popular attack way, and be atttacked with SQL infuse especially among them and cross station script attack to attach most importance to, the lawful sex that infuse of so called SQL is atttacked even if uses programmer to do not have pair of user data-in when writing code undertakes judging, bring about the person that inbreak to be able to command through insert and carrying out baleful SQL, obtain data to read the attributive; that take and revises and attack of the script that cross a station is join baleful code through be in the webpage, when the person that visit browses a webpage, the administrator of means prevail on that baleful code can be carried out or ceases through giving an administrator post a letter is browsed, win administrator limits of authority thereby, control whole website.

据动易公司网络安全专家介绍：根据2007年 OWASP 组织发布的 Web 应用程序脆弱性10大排名的统计结果表明，跨站脚本、注入漏洞、跨站请求伪造、信息泄露等方面的问题仍然是现在黑客流行的攻击方式，而其中尤以SQL注入攻击和跨站脚本攻击为重，所谓的SQL注入攻击就是利用程序员在编写代码时没有对用户输入数据的合法性进行判定，导致入侵者可以通过插入并执行恶意SQL命令，获得数据读取和修改的权限；而跨站脚本攻击则是通过在网页中加入恶意代码，当访问者浏览网页时，恶意代码会被执行或者通过给治理员发信息的方式诱使治理员浏览，从而获得治理员权限，控制整个网站。

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.

After discussion of the relation of MR〓 and ALT, an algorithm proposed by Zhongping Qin and Huanguo Zhang, two conclusions are obtained: if a weak key can be successfully attacked by the method of reduced echelon matrix, it can also be successfully attacked by a linear R〓R〓 transformation; meanwhile, there exists such a weak key that can be successfully attacked by the algorithm MR〓 or linear R〓R〓 transformation, but this key can not be successfully attacked by the algorithm ALT. For a NFA, according to the number of solutions for the image equation of its R〓R〓 transformation, there exist two sufficient criteria about its weak invertibility and weak inverse.

通过比较MR〓与覃中平和张焕国提出的攻击FAPKC加密情形的算法ALT，证明了如下结果：凡用约化梯阵方法能攻击成功，用线性R〓R〓变换也能攻击成功；同时，存在着用算法MR〓或线性R〓R〓变换攻击成功的弱密钥，用算法ALT攻击失败。

The intersexual aggression of male was significantly higher than the intersexual aggression of female and the intrasexual aggression of male. There was significant difference about male's aggression between two groups; but for female, there was no significant difference. The combat occurred intensely when two females met whether in male vs female or female vs female, but were both higher than the intrasexual aggression of male. With the increasing of meeting time, the male and female in female vs female decreased their aggression; the female in female vs male kept its aggression in high level. The component of aggression was resembled to the exhibition of aggression in every group.

同性个体间雄性动物的攻击水平显著高于同性个体间雌性动物的攻击水平和异性个体间雄性动物的攻击水平；同性个体间雌性动物的攻击水平和异性个体间雌性动物的攻击水平没有差异，但两者均高于异性个体间雄性动物的攻击水平；雄性动物和雌雌组中雌性动物的攻击行为均随着熟悉程度的增加而减弱；雌雄组中雌性动物的攻击行为在各时间段的差异不大。

If someone increases his aggressive behaviors, the aggression of the whole group will increase; 5 the aggressive behaviors of juvenile delinquents are rectifiable. It is effective by means of group training .

个体攻击行为的增多会带动整个群体攻击行为的增多，个体攻击行为的减少会带动整个群体攻击行为的减少；（5）越轨少年的攻击行为是可以矫治的，团体训练是一种比较有效的方法。
