【Abstract】: With the gradual improvement of Internet technology, the complexity of the network environment is also increasing. At this time, the assessment of the network service situation can effectively help people to judge the current network service situation and predict the possible security problems in advance, which is conducive to improving the quality of network service and network security in an all-round way. For this reason, this paper will start with a brief description of the basic connotation of network situation assessment. On the basis of constructing the index system of network situation assessment, it will make a brief analysis and Research on the method of network service situation assessment based on fuzzy mathematics.
【Key words】: Fuzzy mathematics; Network services; Situation assessment
0 ?引言
在模數(shù)數(shù)學(xué)[1]思想當(dāng)中,其重點(diǎn)對不確定性事物進(jìn)行研究。而由于網(wǎng)絡(luò)服務(wù)態(tài)勢也存在一定模糊性和不確定性,各項(xiàng)網(wǎng)絡(luò)服務(wù)態(tài)勢評估指標(biāo)并非固定不變,因此可有效引入模數(shù)數(shù)學(xué)的概念進(jìn)行網(wǎng)絡(luò)服務(wù)態(tài)勢評估。通過采用基于模糊數(shù)學(xué)的網(wǎng)絡(luò)服務(wù)態(tài)勢評估[2]方法,可以在準(zhǔn)確評估網(wǎng)絡(luò)服務(wù)態(tài)勢情況的同時(shí)為相關(guān)決策提供重要參考依據(jù)。
1 ?網(wǎng)絡(luò)態(tài)勢評估的基本內(nèi)涵
在網(wǎng)絡(luò)態(tài)勢感知當(dāng)中,網(wǎng)絡(luò)態(tài)勢評估占據(jù)著毋庸置疑的核心地位。所謂的網(wǎng)絡(luò)態(tài)勢評估指的就是基于大規(guī)模網(wǎng)絡(luò)[3]環(huán)境中,于level1初步處理融合獲取的所有網(wǎng)絡(luò)監(jiān)測數(shù)據(jù)后,依照領(lǐng)域知識與歷史數(shù)據(jù),通過靈活運(yùn)用相應(yīng)的數(shù)據(jù)工具或數(shù)學(xué)模型,在分析推理的基礎(chǔ)上合理解釋目前網(wǎng)絡(luò)具體運(yùn)行狀態(tài)。簡單來說,網(wǎng)絡(luò)態(tài)勢評估即為態(tài)勢因子集合到態(tài)勢空間的映射。……
