Recurrent Neural Network Language Models for Open Vocabulary Event-Level Cyber Anomaly Detection

1 code implementation2 Dec 2017 Aaron Tuor, Ryan Baerwolf, Nicolas Knowles, Brian Hutchinson, Nicole Nichols, Rob Jasper

By treating system logs as threads of interleaved "sentences" (event log lines) to train online unsupervised neural network language models, our approach provides an adaptive model of normal network behavior.

Faster Fuzzing: Reinitialization with Deep Neural Models

no code implementations8 Nov 2017 Nicole Nichols, Mark Raugas, Robert Jasper, Nathan Hilliard

We improve the performance of the American Fuzzy Lop (AFL) fuzz testing framework by using Generative Adversarial Network (GAN) models to reinitialize the system with novel seed files.
