A Novel Trust Taxonomy for Shared Cyber Threat Intelligence

A Novel Trust Taxonomy for Shared 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...
