gym-idsgame is a reinforcement learning environment for simulating attack and defense operations in an abstract network intrusion
game. The environment extends the abstract model described in (Elderman et al. 2017). The model constitutes a
two-player Markov game between an attacker agent and a defender agent that face each other in a simulated computer
network. The reinforcement learning environment exposes an interface to a partially observed Markov decision process
(POMDP) model of the Markov game. The interface can be used to train, simulate, and evaluate attack- and defend policies against each other.
Moreover, the repository contains code to reproduce baseline results for various reinforcement learning algorithms, including:
- Tabular Q-learning
- Neural-fitted Q-learning using the DQN algorithm.
- REINFORCE with baseline
- Actor-Critic REINFORCE
- PPO

ABSTRACT="We present a method to automatically find security strategies for the use
case of intrusion prevention. Following this method, we model the
interaction between an attacker and a defender as a Markov game and let
attack and defense strategies evolve through reinforcement learning and
self-play without human intervention. Using a simple infrastructure
configuration, we demonstrate that effective security strategies can emerge
from self-play. This shows that self-play, which has been applied in other
domains with great success, can be effective in the context of network
security. Inspection of the converged policies show that the emerged
policies reflect common-sense knowledge and are similar to strategies of
humans. Moreover, we address known challenges of reinforcement learning in
this domain and present an approach that uses function approximation, an
opponent pool, and an autoregressive policy representation. Through
evaluations we show that our method is superior to two baseline methods but
that policy convergence in self-play remains a challenge."

A rich set of configurations of the Markov game are registered as openAI gym environments.
The environments are specified and implemented in gym_idsgame/envs/idsgame_env.py see also gym_idsgame/__init__.py.
This is an environment where the agent is supposed to play the attacker in the Markov game and the defender is following the defend_minimal baseline defense policy.
The defend_minimal policy entails that the defender will always defend the attribute with the minimal value out of all of its neighbors.

This is an environment where the agent is supposed to play the defender and the attacker is following the attack_maximal baseline attack policy.
The attack_maximal policy entails that the attacker will always attack the attribute with the maximum value out of all of its neighbors.

This is an environment where neither the attacker nor defender is part of the environment, i.e. it is intended for 2-agent simulations or RL training. In the experiments folder you can see examples of using this environment for training PPO-attacker vs PPO-defender, DQN-attacker vs REINFORCE-defender, etc..
