This project is a basic implementation of the controller module for a Software Defined Perimeter (SDP). This code has been tested on *nix type systems only.

For more information on SDP, see the following sites:




To use this module:

  1. Install Node.js on your system. For details, see https://nodejs.org/en/download/

  2. Install the node package manager (npm) if it was not automatically installed in step 1. Check by opening a terminal and entering:


  3. Clone this project.

  4. Install the node packages that this project requires. Do this by navigating to this project folder in a terminal and entering:

    npm install

  5. Install MySQL.

  6. In MySQL, import the sample database provided with this project in file ./setup/sdp.sql

  7. In MySQL, setup a user with write privileges for this new database.

  8. In MySQL, populate the relevant tables with controller, gateway, and client information. At a minimum, a basic setup would have at least one controller, gateway, and client, requiring the following tables to be populated:

    a. sdpid – at least one entry for each of the three required components

    b. service – the controller should be included as an entry in this table

    c. service_gateway – for each active service, there should be at least one entry declaring the gateway(s) by which it is protected. There can be multiple instances of a service and/or multiple gateways protecting a service instance.

    d. sdpid_service – which SDP IDs have access to a service. Remote gateways must have an entry here, providing access to the controller if the controller is behind another gateway.

    The controller can also use ‘groups’ to provide access to services. In this scenario, rather than adding an entry for a SDP ID in the sdpid_service table above, the administrator can create entries in the following additional tables:

    a. user

    b. group

    c. user_group

    d. group_service

    The following tables are currently placeholders that may prove important later:

    a. controller

    b. gateway

    c. gateway_controller

  9. In the SDPcontroller project, edit ./config.js based on previous steps. The options are explained throughout the configuration file.

  10. If not already installed, install openssl

  11. Create a certificate authority key and certificate using the following command in the terminal:

    openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:4096 -keyout ca.key -out ca.crt

  12. Generate sample keys and certs for each SDP component. This step assumes that a complete set of information about each SDP ID (the controller, gateway(s), and client(s)) was entered into the database. In a terminal, navigate to the SDP controller source code directory and execute:

    node ./genCredentials.js SDPID

    where SDPID is an existing ID in the database such as 12345. This command will create three new files in the current directory: 12345.crt, 12345.key, and 12345.spa_keys. The program will store the SPA keys in the controller database automatically. The crt and key files must be transferred to the device in question. The spa_keys file is only for added convenience in copying the SPA key material to the intended device. The file itself is not used by any of the components. The SPA key material must be entered into the respective device’s .fwknoprc file and sdp_ctrl_client.conf file.

  13. To start the controller, in a terminal enter:

    node ./sdpController.js

  14. See the following sites for more information about the other required SDP components, namely the SDP gateway and SDP client. Both are provided via the github project at:
