面向攻击面收敛的网络安全风险治理研究OA
Research on network security risk governance oriented to attack surface convergence
针对组织网络攻击面动态变化和防御者视角不能有效识别黑客攻击手段的特点,基于多维攻击者视角构建以"资产管理、攻击面识别与风险值计算、攻击面修复与闭环验证、网络流量采集与实时监控分析"为流程的攻击面收敛管理体系,有效实现"安全左移".对已知资产、影子资产等计入纳管范围,融合风险量化分级与安全漏洞闭环验证,开启持续监控以实时感知资产异动并采取措施.实践结果证明,引入网络流量与威胁情报的协同分析后,威胁情报命中安全事件数量逐步下降;网址及端口非必要暴露面得到有效监控与响应,平均暴露时间显著缩短,从数天减少至1h以内.攻击面管理技术有效缓解了攻防不对称性问题,提升了组织在网络攻击面的全局可见性与风险控制效率.
In view of the dynamic changes of the organization's network attack surface and the fact that the defender's perspective can't effec-tively identify the hacker's attack means,based on the multidimensional attacker's perspective,an attack surface convergence management sys-tem with the process of"asset management,attack surface identification and risk value calculation,attack surface repair and closed-loop verifi-cation,network traffic collection and real-time monitoring and analysis"is constructed to effectively realize the"safe left shift".The known as-sets and shadow assets are included in the scope of custody,and the risk quantification and classification and closed-loop verification of security vulnerabilities are integrated.Continuous monitoring is enabled to detect asset changes in real time and take measures.The practice results show that after introducing the collaborative analysis of network traffic and threat intelligence,the number of security incidents hit by threat in-telligence has gradually decreased;the non essential exposure surfaces of websites and ports have been effectively monitored and responded to,and the average exposure time has been significantly shortened from several days to less than one hour.The attack surface management technol-ogy effectively alleviates the asymmetry of attack and defense,and improves the overall visibility and risk control efficiency of the organization in the network attack surface.
