    摘要:

    當前網(wǎng)絡(luò )技術(shù)迅猛發(fā)展,網(wǎng)絡(luò )安全問(wèn)題日益突出,尤其是訪(fǎng)問(wèn)控制安全性。為了解決目前網(wǎng)絡(luò )系統中存在的威脅檢測精度和安全訪(fǎng)問(wèn)控制問(wèn)題,引入SPEA-II算法,提出一種新的網(wǎng)絡(luò )多層次安全訪(fǎng)問(wèn)控制方法。深入分析網(wǎng)絡(luò )多層次訪(fǎng)問(wèn)控制機制原理,明確安全訪(fǎng)問(wèn)控制目標。結合網(wǎng)絡(luò )邊界區域、傳輸信道區域、移動(dòng)終端設備區域,建立邊界訪(fǎng)問(wèn)控制目標函數、安全威脅檢測目標函數、用戶(hù)身份認證目標函數,提高網(wǎng)絡(luò )系統安全威脅檢測精度。利用SPEA-Ⅱ算法對聯(lián)合目標函數進(jìn)行求解,獲取網(wǎng)絡(luò )多層次安全訪(fǎng)問(wèn)控制機制最佳方案。通過(guò)迭代逐漸接近近似最優(yōu)解集,建立最優(yōu)安全策略組合,計算攻擊流量因子完成網(wǎng)絡(luò )多層次安全訪(fǎng)問(wèn)控制。實(shí)驗結果表明,所提方法的網(wǎng)絡(luò )多層次威脅檢測精度為94%,安全評估為0.96。由此證明,所提方法的網(wǎng)絡(luò )多層次安全訪(fǎng)問(wèn)控制效果較好,具有較強的安全性和適應性,能夠為中移互聯(lián)網(wǎng)領(lǐng)域的網(wǎng)絡(luò )安全策略提供技術(shù)支持。

    Abstract:

    At present, with the rapid development of network technology, network security issues are increasingly prominent, especially access control security. In order to solve the problems of threat detection accuracy and security access control in current network systems, SPEA-II algorithm is introduced, and a new network multi-level security access control method is proposed. In-depth analysis of the principle of network multi-level access control mechanism, clear security access control objectives. Combined with the network boundary area, transmission channel area and mobile terminal equipment area, the boundary access control objective function, security threat detection objective function and user identity authentication objective function are established to improve the security threat detection accuracy of the network system. SPEA-II algorithm is used to solve the joint objective function, and the best scheme of network multi-level security access control mechanism is obtained. Through iteration, the approximate optimal solution set is gradually approached, the optimal security policy combination is established, and the attack traffic factor is calculated to complete the multi-level security access control of the network. The experimental results show that the detection accuracy of the proposed method is 94% and the security assessment is 0.96. This proves that the multi-level network security access control effect of the proposed method is good, with strong security and adaptability, and can provide technical support for the network security strategy in the field of China Mobile Internet.
