Peer-to-peer networks offer an alternative for sharing threat intelligence but face challenges in verifying the trustworthiness of participants, including potential malicious actors. +The Fides Module, based on [research](https://github.com/stratosphereips/fides/tree/bfac47728172d3a4bbb27a5bb53ceef424e45e4f) by Lukáš Forst, addresses these challenges by providing a trust model for peer-to-peer networks. It evaluates peer behavior, considers membership in trusted organizations, and assesses incoming threat data to determine reliability. Fides aggregates and weights data to enhance intrusion prevention systems, even in adversarial scenarios. Experiments show that Fides can maintain accurate threat intelligence even when 75% of the network is controlled by malicious actors, assuming the remaining 25% are trusted. ## How to use ### **Communication** The module uses Slips' Redis to receive and send messages related to trust and P2P connection and data evaluation.
