As with any vulnerability analysis , we start by identifying the components and their external communication paths 與任何漏洞分析一樣,我們從確定組件及其外部通信路徑開始。

4 ) combining the scene simulation technology based pc with the simulation model for seismic damage illustration , the buildings earthquake damage illustration system ( embryo ) is estabished . we adopted a mixed - language programming model using visual basic , visual c + + and vba and provided good files management and powerfully database supporting . with the functions of vulnerability analysis , automatic documents processing and earthquake damage illustration , the software can be used for the seismic damage forecast and earthquake damage illustration for sevarel types of common buildings 4 )利用基于pc的視景仿真技術(shù),結(jié)合房屋震害的仿真模型,開發(fā)了房屋震害演示系統(tǒng)(雛形) 。該系統(tǒng)采用了visualbasic + vba + visualc + +的混合編程模型,具有完善的文件管理功能和強(qiáng)大的數(shù)據(jù)庫支持。該系統(tǒng)兼具易損性分析、自動(dòng)文檔處理和震害特征演示三項(xiàng)功能,既可以用于常見房屋的單體震害預(yù)測(cè),亦可用于常見房屋單體震害特征的直觀演示。
The following are the main achievements : distributed network measurement and analysis infrastructure ( dnmai ) , the cooperant result of all the researchers of our workgroup , is discussed in detail , and also the important status of the network intrusion detection and network vulnerability analysis in dnmai 研究成果如下:系統(tǒng)地介紹了本項(xiàng)目組全體成員共同創(chuàng)作的一種分布式網(wǎng)絡(luò)測(cè)量與分析基礎(chǔ)架構(gòu)dnmai ( distributednetworkmeasurementandanalysisinfrastructure )及網(wǎng)絡(luò)入侵檢測(cè)系統(tǒng)和網(wǎng)絡(luò)脆弱性分析系統(tǒng)在其中的重要地位和作用。
Representation , classification and global reference name standard of the common security knowledge , are summarized . then a new model of system security trend analysis is presented , which combines vulnerability analysis ( using privilege graph analysis method ) and attack knowledge analysis ( using goal tree analysis method ) 本論文首次從信息對(duì)抗的角度分析了公共知識(shí)獲取和安全趨勢(shì)分析的意義,系統(tǒng)總結(jié)了公共知識(shí)分類、標(biāo)準(zhǔn)與知識(shí)描述等方面問題,給出動(dòng)態(tài)防御系統(tǒng)中公共知識(shí)獲取的方法,提出了權(quán)限圖與攻擊樹相結(jié)合的目標(biāo)系統(tǒng)安全趨勢(shì)分析方法。
According to working process of terminal - sensitive projectile using capturing rule of detector , on the basis of vulnerability analysis to self - mechanized gun , a model of injuring target about terminal - sensitive projectile is established in this paper . and on the basis of it , using monte - carlo method , numerical simulating computation is done . according to result analysis , the maximum sensitive factor of terminal - sensitive projectile ' s performance is found , the scientific foundations supplied for determining structural parameter and performance parameter of terminal - sensitive projectile are provided 在此基礎(chǔ)上,根據(jù)末敏彈工作過程和探測(cè)器采用的捕獲準(zhǔn)則,在對(duì)自行火炮進(jìn)行易損分析基礎(chǔ)上,建立了末敏彈毀傷目標(biāo)模型,并在此基礎(chǔ)上,采用了蒙特卡羅法進(jìn)行大量的數(shù)值模擬計(jì)算,對(duì)結(jié)果進(jìn)行分析,找出了影響末敏彈的最敏感因素,為末敏彈結(jié)構(gòu)參數(shù)、性能參數(shù)的優(yōu)化提供了依據(jù)。
Fifthly , one agent - based network vulnerability analysis system ( briefly named anvas ) is designed , and some key technologies of the anvas are studied and analyzed . the mpi - based algorithm for vulnerability information quick collection and relation model - based method for vulnerability analysis are proposed 設(shè)計(jì)一個(gè)基于主體網(wǎng)絡(luò)脆弱性分析系統(tǒng)anvas ,并研究分析anv人s中的關(guān)鍵技術(shù),提出了基于mpi的脆弱信息快速采集算法和基于關(guān)系模型的脆弱性關(guān)聯(lián)分析方法。
