Abstract

Network Behavior Anomaly Detection (NBAD) and User and Entity Behavior Analytics (UEBA) are heralded as machine learning fueled messiahs for finding advanced attacks. The data collection and processing methodologies of these approaches create a series of new exploitable vectors that can allow attackers to navigate network and systems undetected. In this session, methods for poisoning data, transforming calculations and preventing alerts will be examined. Proof of concept code will be demonstrated and made available. Approaches to harden against these attacks will also be discussed as well as outlining needed changes in detection standards.

Co-founder & Chairman, WitFoo

I started WitFoo in 2016 to make information and operations shareable across the craft of cybersecurity — between companies, law enforcement, national security and insurers, who mostly cannot see what each other sees. Before that I was at Lancope and Cisco, and I began in 2002 as Network Security Officer for the Naval Postgraduate School.

I lead research and development on a platform that ingests trillions of messages a day across hundreds of clusters. It is sold as Conductor, Reporter and Analytics, licensed flat per appliance with unlimited data — because a team charged by the gigabyte ends up making coverage decisions on a spreadsheet, months before the incident that needed the logs they dropped.

Everything here is mine, not the company's, and it wanders. Corrections are genuinely welcome — I would rather be right than consistent.

A note on how this was written: I use artificial intelligence tools to help me research, check facts, and edit these posts. The ideas, the arguments, and any mistakes are mine. I read the sources, I check the claims, and I take full responsibility for what I publish here. The views are my own and the writing is my intellectual property.
