Jared Chandler


I'm a PhD candidate at Tufts University working under the supervision of Dr. Kathleen Fisher. My research focuses on automatic protocol reverse engineering, network security, and cyber-deception. My work leverages artificial intelligence (AI), programming languages (PL), and machine learning (ML) to tackle difficult computer security problems. I also have an extensive background in visualization and data science.

Current Research Projects

Automatic Protocol Reverse Engineering
I am currently exanding my approaches to automatic protocol reverse engineering. My goal is a fully automated approach to infering semantic descriptions using only passively collected network traces. This work is valuable for identifying security vulnerabilities in proprietary and adversary systems, for uncovering the specifications of legacy equipment, and for validating that an on-the-wire format is faithful to a given specification.

Botnet Scanning Countermeasures
I am currently exploring network counter-measures to delay, deter, and defeat scanning by malicious botnets. Described succinctly as "Anti-Botnet Network Landmines".

Usable Tools for Protocol Reverse Engineering
I am developing user-facing tools to assist reverse engineers with analyzing unknown protocol data. While tools such as GHIDRA and IDA Pro exist for reverse engineering binary executables, specialized tools for binary protocols do not currently exist.

Synthesizing Network Attack Traffic
I am actively exanding my approaches for generating synthetic network attack traffic. This line of research builds on my earlier work leveraging intrusion detection system (IDS) rules as a cook-book for creating look-alike traffic.

Visualizations

While my current work is focused on applied research for computer security, I have an extensive background in visualization, design, human computer interfaces (HCI) and user-interfaces (UX). Below are a few examples. A larger portfolio is here.


Parallel coordinates interface with adjustable error bounds.


Scalable squarified treemaps for reasoning about file permissions.


Interactive SQL query visualization.


3D printed tangible grammars.



Music

In my free time I experiment with electronic music. Modular analog synthesizers allow control and audio signals to be interchanged in a manner analagous to how computers can intepret binary data either as instruction (code) or data to be operated on. I enjoy the parallels between modular synthesizers and functional programming.
