Recent Research
Network Detection of Interactive SSH Impostors Using Deep Learning
Impostors who have stolen a user's SSH login credentials can inflict significant harm to the systems to which the user has remote access. We consider the problem of identifying such imposters when they conduct interactive SSH logins by detecting discrepancies in the timing and sizes of the client-side data packets, which generally reflect the typing dynamics of the person sending keystrokes over the connection.
GGFAST: Automating Generation of Flexible Network Traffic Classifiers
When employing supervised machine learning to analyze network traffic, the heart of the task often lies in developing effective features for the ML to leverage. We develop GGFAST, a unified, automated framework that can build powerful classifiers for specific network traffic analysis tasks, built on interpretable features. The framework uses only packet sizes, directionality, and sequencing, facilitating analysis in a payload-agnostic fashion that remains applicable in the presence of encryption.
