analyzer-d4-passivedns

analyzer-d4-passivedns is an analyzer for a D4 network sensor. The analyser can process data produced by D4 sensors (in passivedns CSV format (more to come)) and ingest these into a Passive DNS server which can be queried later to search for the Passive DNS records.

Features

• A D4 analyzer which can be plugged to one or more D4 servers to get a stream of DNS records
• A compliant Passive DNS ReST server compliant to Common Output Format
• A flexible and simple analyser which can be configured to collect the required records from DNS records

Overview

Requirements

• Python 3
• Redis >5.0
• Tornado
• iptools

Install

./install_server.sh

All the Python 3 code will be installed in a virtualenv (PDNSENV).

Running

Start the redis server

Don't forget to set the DB directory in the redis.conf configuration. By default, the redis for Passive DNS is running on TCP port 6400

./redis/src/redis-server ./etc/redis.conf

Start the Passive DNS COF server

. ./PDNSENV/bin/activate
cd ./bin/
python3 ./pdns-cof-server.py

Configure and start the D4 analyzer

cd ./etc
cp analyzer.conf.sample analyzer.conf

Edit the analyzer.conf to match the UUID of the analyzer queue from your D4 server.

[global]
my-uuid = 6072e072-bfaa-4395-9bb1-cdb3b470d715
d4-server = 127.0.0.1:6380
# INFO|DEBUG
logging-level = INFO

then you can start the analyzer which will fetch the data from the analyzer, parse it and populate the Passive DNS database.

. ./PDNSENV/bin/activate/
cd ./bin/
python3 pdns-ingestion.py
