Wendigo Code Breakdown

The Wendigo code consists of the following sections:

• attack: The code and results used to run the DoS impact evaluation which utilized the found query to perform a mock DoS attack.
• environments: The environment is broken down into a parent and subclass.
  • GraphQLEnv.py: handles the docker and connection,
  • GraphQLDoSEnv.py: performs handles the mappings between agent's state/action and queries.
• models: This directory contains the code for PPO and Random.
  • PPO.py: Contains the PPO code utilized for the evaluation of the paper and is a modified version of cleanrl's PPO implementation.
  • Random.py: Contains the implementation used for random evaluation of the paper (note: greedy is a setting in the attack settings).
• results: This directory contains pickles of the results presented in the paper.
• schemas: This contains the DVGA schema used to inform the environment for state to query space mappings.
• settings: This directory contains the settings files used in the evaluation (Has its own read me for clarity on the settings).
• utils: Contains helper functions and functions to interface between the agent and environment.
• main.py: This file is used to run the application by specifying the variables below the application will load the appropriate setting file and run the experiment.
  • MODEL: 'PPO' or 'Random'
  • TEST: currently only 'DoS' is supported
  • DESC: 'Regular', 'Large', 'Greedy-Regular' or 'Greedy-Large'
