Security Policy Conflict Detection in SDN

This project dynamically detects the con-compliant security flow rules based on user Intents.

Contributor

Neha Vadnere

System Requirements

  • OS: Ubuntu 18.04
  • SDN Controller: ONOS
  • Data-plane emulation: Mininet
  • Supporting Software Packages: Python2.7, python-3.6, git, zip, curl, unzip, bazel-3.0.0, mavel-3.3.9, karaf-3.0.5, java-11

Installation

Install required software packages first. Start ONOS controller and run a sample mininet topology.

To run ONOS controller server in localhost -

bazel run onos-local -- clean build

To start given mininet topology, run this command in separate terminal.

sudo ./run.sh

Start ONOS cli in a new terminal.

cd $ONOS_ROOT (where you have installed ONOS)
./tools/test/bin/onos onos@localhost
(Default password: rocks)

Start required packages to start openflow services and basic l2 forwarding services in ONOS cli window.

onos > app activate org.onosproject.openflow
onos > app activate org.onosproject.fwd

Add any required intent request in onos cli. (Example given below)

onos > add-host-intent 00:00:00:00:00:01/None 00:00:00:00:00:02/None 

This will add a new Intent from host h1 to h2. (00:00:00:00:00:01/None si host h1's id and 00:00:00:00:00:02/None is host h2's id.

Add some flowrule to drop the packets based on specific criteria. One example is given below.

python3 DefaultDropApp_poc.py

Run some functions to start off the applications.

python3 main.py

You can see the results of the reports generated in "Results" folder. report.txt will display consolidated report of number of conflicts detected and details of that conflict.
