MITRE Caldera™ for OT Plugins

A collection of plugins that extend MITRE Caldera™ to the Operational Technology (OT) environment.

It is built on the MITRE ATT&CK® for ICS framework.

This repository contains all the Caldera for OT plugins as git submodules. As described in each individual plugin README, it is also possible to git clone a specific protocol plugin directly into the Caldera plugins directory, following the "Installation" guidance.

Install Caldera for OT Plugins

To install all the Caldera for OT plugins, use the recursive flag while cloning this repository:

git clone https://github.com/mitre/caldera-ot.git --recursive

Note, that after performing the git clone, you will still need to:

1. Ensure the plugin(s) of interest are moved into the caldera/plugins directory of your caldera instance
2. Enable the plugin(s) by adding their names to the conf/local.yml or conf/default.yml (if running Caldera in insecure mode)

For example,

- bacnet
- dnp3
- modbus
- profinet
- iec61850

The OT plugins can also be setup individually:

• bacnet
• dnp3
• modbus
• profinet
• iec61850

Installing the IEC 61850 Payloads

Using the IEC 61850 plugin requires the additional step of installing the plugin's payloads by following these steps:

1. Download the appropriate compiled payload from the Releases section of the iec61850-payloads repository.
2. Save the downloaded payload file(s) in the caldera/plugins/iec61850/payloads directory of your Caldera installation.

What are the Caldera for OT plugins?

The Caldera for OT plugins unify and expose open-source OT protocol libraries in the form of protocol specific plugins:

• bacnet - for the Building Automation and Control Networks (BACnet) protocol
• dnp3 - for the Distributed Network Protocol 3 (DNP3)
• modbus - for the Modbus protocol
• profinet - for the Profinet protocol - Basic Discovery and Configuration Protocol (DCP) only
• iec61850 - for the IEC 61850 series of communication protocols - Manufacturing Message Specification (MMS) only

Each plugin contains the following documentation:

• High-level README.md
• Source code specific README.md (located under /src)
• Caldera Field Manual documentation (located under /docs)

What is the motivation for the plugins?

The Caldera for OT plugins enable adversary emulation in the OT environment, which supports traditional Caldera use cases. For example, training and testing of operators and defenses.
