重新思考信息共享以实现可操作的威胁情报

Rethinking Information Sharing for Actionable Threat Intelligence

Aziz Mohaisen, Omar Al-Ibrahim, Charles Kamhoua, Kevin Kwiat, Laurent Njilla

摘要:

在过去十年中,信息安全和威胁形势显著增长,使得单个防御者难以同时防御所有攻击。这需要引入信息共享,这是一种在信任社区中共享威胁指标以促进防御的范例。在文献中提出了指标的表示、交换和消费的标准,尽管各种问题被削弱了。在本文中,我们通过强调值得进一步探讨的各种问题,重新思考可操作情报的信息共享。我们认为,信息共享可以受益于定义良好的使用模型,威胁模型,通过测量和鲁棒的评分,良好理解和保存的指标的隐私和质量,以及鲁棒的机制,以避免搭便车行为的自私代理。我们呼吁利用数据和社区结构的差异性来优化共享。

英文摘要:

In the past decade, the information security and threat landscape has grown significantly making it difficult for a single defender to defend against all attacks at the same time. This called for introduc- ing information sharing, a paradigm in which threat indicators are shared in a community of trust to facilitate defenses. Standards for representation, exchange, and consumption of indicators are pro- posed in the literature, although various issues are undermined. In this paper, we rethink information sharing for actionable intelli- gence, by highlighting various issues that deserve further explo- ration. We argue that information sharing can benefit from well- defined use models, threat models, well-understood risk by mea- surement and robust scoring, well-understood and preserved pri- vacy and quality of indicators and robust mechanism to avoid free riding behavior of selfish agent. We call for using the differential nature of data and community structures for optimizing sharing.
