Cyber threat intelligence is a relatively new field that has grown from two distinct fields, cyber security and intelligence. As such, it draws knowledge from and mixes the two fields. Yet, looking into current scientific research on cyber threat intelligence research, it is relatively scarce, which opens up a lot of opportunities. In this paper we define what cyber threat intelligence is, briefly review some aspects for cyber threat intelligence. Then, we analyze existing research fields that are much older that cyber threat intelligence but related to it. This opens up an opportunity to draw knowledge and methods from those older field, and in that way advance cyber threat intelligence much faster than it would by following its own path. With such an approach we effectively give a research directions for CTI.

网络威胁情报研究方向

网络威胁情报是一个相对较新的领域，它从两个不同的领域发展而来，网络安全和情报。因此，它从两个领域汲取知识并将其混合在一起。然而，纵观当前关于网络威胁情报研究的科学研究，它相对稀缺，这开辟了很多机会。在本文中，我们定义了什么是网络威胁情报，简要回顾了网络威胁情报的一些方面。然后，我们分析了比网络威胁情报更古老但与之相关的现有研究领域。这为从那些较旧的领域汲取知识和方法提供了机会，从而比走自己的路更快地推进网络威胁情报。通过这种方法，我们有效地为 CTI 提供了研究方向。
