DELTA - SDN Security Evaluation Framework

enter image description here
DELTA is a penetration testing framework that regenerates known attack scenarios for diverse test cases. This framework also provides the capability of discovering unknown security problems in SDN by employing a fuzzing technique.
  • Agent-Manager is the control tower. It takes full control over all the agents deployed to the target SDN network.
  • Application-Agent is a legitimate SDN application that conducts attack procedures and is controller-dependent. The known malicious functions are implemented as application-agent functions.
  • Channel-Agent is deployed between the controller and the OpenFlow-enabled switch. The agent sniffs and modifies the unencrypted control messages. It is controller-independent.
  • Host-Agent behaves as if it was a legitimate host participating in the target SDN network. The agent demonstrates an attack in which a host attempts to compromise the control plane.
Prerequisites In order to build and run DELTA, the following are required:
  • An agent manager based on Ubuntu 14.04 LTS 64 bit
    • Ant build system
    • Maven v3.3.9
    • Vagrant
    • JDK 1.7 and 1.8
  • Target Controller (for application agent)
    • Floodlight: 0.91, 1.2
    • ONOS: 1.1, 1.6, 1.9
    • OpenDaylight: Helium-sr3, Carbon
  • Cbench (for channel agent)
  • Mininet 2.1+ (for host agent)
  • (in the case of All-In-One Single Machine) Three virtual machines based on Ubuntu 14.04 LTS 64 bit.
    • VM-1: Target controller + Application agent
    • VM-2: Channel agent
    • VM-3: Host agent
Installing DELTA DELTA installation depends on maven and ant build system. The mvn command is used to install the agent-manager and the agents. DELTA can support an All-In-One Single Machine environment via virtual machines as well as a real hardware SDN environment.
STEP 1. Get the source code of DELTA on the agent manager machine
$ git clone
STEP 2. Install DELTA dependencies
$ cd <DELTA>/tools/dev/delta-setup/
$ ./delta-setup-devenv-ubuntu
STEP 3. Install DELTA using maven build
$ cd <DELTA>
$ source ./tools/dev/delta-setup/bash_profile
$ mvn clean install
STEP 4-a. (All-In-One Single Machine) Install three virtual machines using vagrant system
$ cd <DELTA>/tools/dev/delta-setup/
$ ./delta-setup-vms-ubuntu
$ cd vagrant/
$ vagrant up
STEP 4-b. (All-In-One Single Machine) Add NAT to VM3 (mininet)

In the case of all-in-one single machine, the test environment is automatically setup as below:

Configuring your own experiments Execute sudo without the password
$ sudo visudo
In the bottom of the file, type the follow:
Configure passwd-less ssh login for the agents
$ vi <DELTA>/tools/dev/delta-setup/bash_profile
(by default, the addresses are set as vms)
export DELTA_APP=vagrant@
export DELTA_CHANNEL=vagrant@
export DELTA_HOST=vagrant@
$ source <DELTA>/tools/dev/delta-setup/bash_profile

$ cd ~
$ ssh-keygen -t rsa
(Press enter)
$ ssh-copy-id -i ~/.ssh/ $DELTA_APP
$ ssh-copy-id -i ~/.ssh/ $DELTA_CHANNEL
$ ssh-copy-id -i ~/.ssh/ $DELTA_HOST

Check if you can access the VMs without having to enter the password.
The agent-manager automatically reads a configuration file and sets up the test environment based on the file. DELTA/tools/config/manager.cfg contains the All-In-One Single Machine configuration by default. If you want to test a real SDN environment, you should specify your own configuration file.
Floodlight 1.2
$ cd <DELTA>/tools/dev/app-agent-setup
$ ./floodlight-1.2-scp
ONOS 1.1
$ cd <DELTA>/tools/dev/app-agent-setup/onos
$ ./onos-1.1.0-scp
(on the controller machine) $ ./onos-1.1.0-setup
ONOS 1.6 or 1.9
$ cd <DELTA>/tools/dev/app-agent-setup/onos
$ ./delta-setup-onos <onos-version>
* Supported ONOS version in the script: 1.6, 1.9 
OpenDaylight helium-sr3 (only JDK 1.7-supported)
$ cd <DELTA>/tools/dev/app-agent-setup
$ ./odl-helium-sr3-scp
(on the controller machine) $ ./odl-helium-sr3-setup
OpenDaylight Carbon
$ cd <DELTA>/tools/dev/app-agent-setup
$ ./odl-carbon-scp
(on the controller machine) $ ./odl-carbon-setup
The app-agent (on the controller machine) needs 'agent.cfg' file to connect to the agent-manager.
Running DELTA STEP 1. Distribute the executable files to VMs
$ cd <DELTA>
$ source ./tools/dev/delta-setup/bash_profile
$ ./tools/dev/delta-setup/delta-agents-scp
STEP 2. Execute Agent-Manager first
$ cd <DELTA>
$ bin/run-delta tools/config/<configuration file> # e.g., manager_vm.cfg
DELTA: A Penetration Testing Framework for Software-Defined Networks
 [pP] - Show all known attacks
 [cC] - Show configuration info
 [kK] - Replaying known attack(s)
 [uU] - Finding an unknown attack
 [qQ] - Quit

STEP 3. Connect Web-based UI (port number is 7070)
