Paradise: Real-Time, Generalized, and Distributed Provenance-Based Intrusion Detection

Identifying intrusion from massive and multi-source logs accurately and in real-time presents challenges for today's users. This article presents Paradise, a real-time, generalized, and distributed provenance-based intrusion detection method. Paradise introduces a novel extract strategy to prune and extract process feature vectors from provenance dependencies at the system log level, and it stores them in high-efficiency memory databases. Using this strategy, Paradise does not depend on the specific operating system type or provenance collection framework. Provenance-based dependencies are calculated independently during the detection phase, thus, Paradise can negotiate all detection results from multiple detectors without extra communication overhead between detectors. Paradise also employs an efficient load-balanced distribution scheme that enhances the Kafka architecture to efficiently distribute provenance graph feature vectors to the detectors. The experimental results demonstrate that our method has a high detection accuracy with a low time overhead.
