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.

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)
  • 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: username ALL=(ALL) NOPASSWD: ALL

  • 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 [email protected] export [email protected] export [email protected] $ 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 &lt;DELTA&gt;/tools/dev/app-agent-setup
$ ./floodlight-1.2-scp

> ONOS 1.1

$ cd &lt;DELTA&gt;/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 &lt;DELTA&gt;/tools/dev/app-agent-setup/onos
$ ./delta-setup-onos &lt;onos-version&gt;
* Supported ONOS version in the script: 1.6, 1.9

> OpenDaylight helium-sr3 (only JDK 1.7-supported)

$ cd &lt;DELTA&gt;/tools/dev/app-agent-setup
$ ./odl-helium-sr3-scp
(on the controller machine) $ ./odl-helium-sr3-setup

> OpenDaylight Carbon

$ cd &lt;DELTA&gt;/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
