Enabling cooperative, multi-domain DDoS defense by distributing attack reports through Ethereum among participating autonomous systems.
The entire system consists of three main components:
Stalk monitors the network traffic of the underlying networking infrastructure
Pollen encapsulates all communication-related tasks, handling the database and Ethereum
BloSS is the core component which receives mitigation requests and signals ongoing attacks through Pollen and stops attack traffic through Stalk
The entire BloSS is written in Python 2.7, so you need to have a working Python installation as well as the required packages, which can be found in python_requirements.txt and can be installed through pip (you can get pip for example through apt-get install python-pip):
pip install -r python_requirements.txt
Create your custom config.ini file by looking at the default_config.ini template.
You need a working instance of InfluxDB for statistical data to be stored and an Ethereum blockchain for the mitigation to work.
The current implementation does not yet support deploying the relay contract automatically. This means, you first need to deploy the relay.sol contract by hand, for example through the Remix IDE. Afterwards, you need to configure the relay contract in the config.ini of each controller by replacing the line from the default config:
RELAY_CONTRACT_ADDRESS = 0xDEADBEEFFEED
with the actual contract address obtained through Remix.
A small initial setup script will soon be provided that automatically deploys the relay contract.
After setting up all relevant components, you can directly start the entire system by issuing:
$ python runner.py --controller stalk/simple_router.py --controller stalk/controller.py
Which starts both a simple packet-forwarding Ryu manager called SimpleRouter as well as the Stalk controller monitoring the network traffic.
