Introduction

This project consists of 3 developments:

  1. XACML_PAP. Offers a web environment to manage subjects, actions and resources and policies.

  2. XAML_ServletPDP. Offers an endpoint to verify if a subject can perform an action over a specific resource through the policies.

  3. XACML_PDP_SunXACML. Contains dependencies needed by XAML_ServletPDP.

Each development corresponds with a subfolder.

Deploying XACML_PAP_PDP (docker-compose)

Configure docker-compose environment variables

Access to XACML_PAP_PDP directory and edit docker-compose to verify environment variables.

  • If you don't need blockchain integration you can remove the "environment" section or define BlockChain_integration=0.

  • If you need blockchain integration (BlockChain_integration=1), you have two ways to configure the integration:

    • Using a configuration file (./PAP/ConfigData/blockchain.conf) : BlockChain_configuration=0

    • Using the environment variables of docker-compose.yml file : BlockChain_configuration=1.

      • BlockChain_protocol=http # Optional: Default value : http
      • BlockChain_domain=testdomain # Required
      • BlockChain_IP=# # Required
      • BlockChain_port=8000 # Optional Default value : 8000
      • BlockChain_get_resource=/policy/testdomain # Optional : Default value : /policy/<BlockChain_domain>
      • BlockChain_post_resource=/policy/register # Optional : Default value : /policy/register
      • BlockChain_update_resource=/policy/update # Optional : Default value : /policy/update

Build the proyect image and run

To build the proyect image and once docker-compose file is reviewed, access to XACML_PAP_PDP directory and run:

./build.sh

When the image was created run it using:

docker-compose up -d

Testing XACML_PAP_PDP

you must obtain a response like this (status=200):

You have to send a POST message with the XACML Request
  • To test a PDP request (policies) you can run:
curl --location --request POST 'http://<XACML-PublicIP>:8080/XACMLServletPDP/' \
--header 'Content-Type: text/plain' \
--data-raw '<Request xmlns="urn:oasis:names:tc:xacml:2.0:context:schema:os">
