Deploying AcuSensor for Node.js - Docker

🔍 AcuSensor Network PreRequisites

AcuSensor makes use of the AcuSensor Bridge. Read more information here.

The most principled way of deploying AcuSensor in a Docker scenario is to simply layer the AcuSensor modifications onto your already existing container definition. This simple example will demonstrate how you can deploy AcuSensor together with your web application.

🔍 Supported Servers and Frameworks

See the manual page Deploying AcuSensor for .Node.js for information regarding supported servers and frameworks.

Create your Target in Acunetix

For this example, we will assume that the URL for your target is http://acunetixexample.com:60000. Create a target with your URL, enable AcuSensor, download the AcuSensor agent file node-acusensor.tar, and save this file for use later on.

Define the Web Application image

This simple web application will be defined through the following file structure:

/testnodejs-docker/

/testnodejs-docker/Dockerfile

/testnodejs-docker/src/app.js

/testnodejs-docker/src/package.json

Create your /testnodejs-docker/Dockerfile file to read as follows:

FROM node:12

#setup the web pages

COPY src/. .

#install npm and dependencies

RUN npm install

Create your /testnodejs-docker/src/app.js file to read as follows:

const app = require('express')();

const port = 60000;

app.get('/', function (req, res) {

  res.send(

  '<html><body>' +

  '<h1>AcuSensor Example for Node.JS</h1>' +

  '<br>' +

  'Hello World! - Main Page' +

  '<br>' +

  '<a href="/page1">Goto Page 1</a>' +

  '</body></html>'

  );

});

app.get('/page1', function (req, res) {

  res.send(

  '<html><body>' +

  '<h1>AcuSensor Example for Node.JS</h1>' +

  '<br>' +

  'Hello World! - Page 1' +

  '<br>' +

  '<a href="/">Goto Main Page</a>' +

  '</body></html>'

  );

});

app.listen(port, function(err){

  if (err) console.log(err);

  console.log("Server listening on port: ", port);

});

Create your /testnodejs-docker/src/package.json file to read as follows:

{

  "name": "testnodejs-docker",

  "version": "1.0.0",

  "dependencies": {

    "express": "*"

  }

}

Finally, build the image with:

cd /testnodejs-docker

docker build -t testnodejs-docker .

Define the AcuSensor layer image

The AcuSensor layer will be defined through the following file structure:

/testnodejs-docker-acusensor/

/testnodejs-docker-acusensor/Dockerfile

/testnodejs-docker-acusensor/node-acusensor.tar

Copy the node-acusensor.tar file you created in the first step to your docker host into the /testnodejs-docker-acusensor directory.

Create your /testnodejs-docker-acusensor/Dockerfile file to read as follows:

FROM testnodejs-docker

#setup and install AcuSensor

RUN mkdir /acusensor

COPY node-acusensor.tar /acusensor/node-acusensor.tar

#expose port and launch the app with AcuSensor

EXPOSE 60000

CMD [ "npx", "/acusensor/node-acusensor.tar", "app.js" ]

Build and run your image with:

cd /testnodejs-docker-acusensor

docker build -t testnodejs-docker-acusensor .

docker run -d -p 60000:60000 --name mytestnodejs testnodejs-docker-acusensor

Test and scan your web application

Point your browser to your web application - in this example http://acunetixexample.com:60000 to confirm it is running as intended; you will get the following:

Finally, run a scan on your target; the Activity panel will confirm that AcuSensor was detected and used for the scan.
