A dataflow system for anomaly detection and analysis

This paper proposes DeADA, a dataflow architecture incorporating an automated, unsupervised and online learning algorithm. Compared with 24 core software implementations, DeADA achieves up to 6.17 times lower data drop rate and 10.7 times higher power efficiency. More importantly, experimental results for the Heartbleed case study suggest that DeADA is capable of detecting unknown attacks under network speeds of at least 18Mbps, a feature which is essential for modern network intrusion detection.
