Cyber Threat Intelligence

Cyber threat intelligence sharing has become a focal point for many organizations to improve resilience against cyberattacks. The objective lies in sharing relevant information achieved through automating as many processes as possible without losing control or compromising security. The intelligence may be crowdsourced from decentralized stakeholders to collect and enrich existing information. Trust is an attribute of actionable cyber threat intelligence that has to be established between stakeholders. Sharing information about vulnerabilities requires a high level of trust because of the sensitive information. Some threat intelligence platforms/providers support trust establishment through internal vetting processes; others rely on stakeholders to manually build up trust. The latter may reduce the amount of intelligence sources. This work presents a novel trust taxonomy to establish a trusted threat sharing environment. 30 popular threat intelligence platforms/providers were analyzed and compared regarding trust functionalities. Trust taxonomies were analyzed and compared. Illustrative case studies were developed and analyzed applying our trust taxonomy.

Cyber Threat Intelligence (CTI) is the emerging strategy of cyber defense which helps organizations to combat the latest and more sophisticated cyber threats. Gathering this threat information, analyzing and communicating it between the security teams is very difficult and challenging because of the heterogeneous aspects involved.  The necessity of sharing the intelligence related data collected by organizations is increasing day by day to counter the ever changing and highly dynamic threat landscape. In this paper an attempt is made to understand CTI concept and how it is collected and analyzed to form useful actionable intelligence are observed. The importance of Threat intelligence sharing, and various standards working in the area of TIS are also mentioned. Finally the primary challenges in TIS are given a light in a broad view
