Multi-Dimensional Trust Model: Towards Multi-Layered Secure Architecture for Enhanced Threat Information Sharing
The trust concept has become more and more popular by paving its way gradually into the modern field. Thus, it becomes a more alluring and attractive solution to secure and protect information sharing against attackers. Indeed, malicious entities can launch intentionally or unintentionally very harmful attacks against the information-sharing process causing network paralysis. In this paper, we propose composite trust-based schemes from the perspective of direct experience and entities’ recommendations to enhance the shared threat information in the public and private communities. Therefore, we introduce a first trust-based model defined by several specific dimensions to improve the security of private/targeted communities. Furthermore, a second trust-based scheme is proposed for the public community where the concept of zero-trust is introduced to enhance the shared critical data inside this open environment. Thus, our proposal reveals a new level of defense against the misbehaving entities by introducing a penalty scheme to punish malicious and suspicious users and to exempt the attackers with continuous misbehaving from participating in the information-sharing process. Extensive simulations demonstrate that the proposed trust-based model provides high stability and resistance in a heavily hostile environment for the public and private communities.
