PRAT is a Protocol Representation and Analysis Toolkit developed at Northeastern University and Worcester Polytechnic Institute. In its current form, it assists an analyst in determining lines of code associated with build-time features. The goal is to debloat network protocol implementations (such as Mosquitto and OpenDDS) and other IoT-related software, by removing features that are not deemed necessary for a particular application.
For a description of what PRAT does, find the paper at: https://web.cs.wpi.edu/~ldecarli/docs/papers/tosem21-debloat.pdf (to appear in the ACM Transactions on Software Engineering and Methodology).
Developed by Ryan Williams (Northeastern) and Tongwei Ren (WPI) under the supervision of Long Lu (Northeastern) and Lorenzo De Carli (WPI).
PRAT is a proof-of-concept provided in the form of a Docker container. The container includes PRAT source code and software artifacts to test PRAT's functioning.
To build the container for PRAT, just run the following command under PRAT/ directory.
sudo docker build -t prat/prat .
PRAT's development was generously funded by the Office of Naval Research under grant N00014-18-1-2660 "Automated Protocol Specialization and Diversification for Individualized Defense".
