【摘要】：在制定網(wǎng)絡(luò)攻擊策略時(shí),目標(biāo)網(wǎng)絡(luò)信息存在不確定性,攻擊方缺乏綜合、可靠、實(shí)時(shí)的攻擊依據(jù),難以達(dá)到攻擊效果,為此提出一種科學(xué)的復(fù)雜網(wǎng)絡(luò)攻擊方法。對(duì)網(wǎng)絡(luò)攻擊中攻擊方收益、損耗、代價(jià)和遇到的風(fēng)險(xiǎn)進(jìn)行分析,建立指標(biāo)體系,利用動(dòng)態(tài)貝葉斯網(wǎng)絡(luò)對(duì)網(wǎng)絡(luò)節(jié)點(diǎn)的攻擊效果進(jìn)行綜合評(píng)估,克服了傳統(tǒng)節(jié)點(diǎn)重要度評(píng)估方法依靠網(wǎng)絡(luò)拓?fù)鋯我恢笜?biāo)或者對(duì)目標(biāo)節(jié)點(diǎn)進(jìn)行靜態(tài)評(píng)估的缺點(diǎn)。仿真實(shí)驗(yàn)表明該方法在攻擊時(shí)綜合了更多節(jié)點(diǎn)關(guān)系和觀測(cè)信息,避免了依靠靜態(tài)評(píng)估手段實(shí)施攻擊時(shí)實(shí)際攻擊效果與理論期望的差距,同時(shí)在攻擊精度上更加準(zhǔn)確,攻擊效能更高。
[Abstract]:When formulating the network attack strategy, the target network information is uncertain, and the attacking party lacks the comprehensive, reliable and real-time attack basis, so it is difficult to achieve the attack effect. Therefore, a scientific and complex network attack method is proposed. This paper analyzes the gains, losses, costs and risks encountered in network attacks, establishes an index system, and evaluates the attacking effect of network nodes by using dynamic Bayesian networks. It overcomes the disadvantage of traditional evaluation method of node importance which depends on single index of network topology or static evaluation of target node. The simulation results show that the method integrates more node relations and observation information, avoids the gap between the actual attack effect and the theoretical expectation when the attack is carried out by static evaluation method, and at the same time, it is more accurate in attacking precision. Attack is more effective.
