Security Test with OWASP ZAP
Security is an important aspect for software applications. ASP.NET Zero includes ready to use files for testing the security of its web application using OWASP ZAP Tool.
To test the web application, you need to install following tools;
After installing the Docker, be sure that you enabled the Kubernetes on Docker by following https://docs.docker.com/desktop/kubernetes/.
Deploying App to Kubernetes
The security test will be runned on an instance of the app which works in Kubernetes. To run our application on Kubernetes, ASP.NET Zero includes Helm charts out of the box. To run our web application on Kubernetes, we must create a Docker image first. To do that, go to folder which contains *.Web.sln file and execute the command below (Don't forget to replace MyCompanyName.AbpZeroTemplate with your project name);
docker build -t abpzerotemplate-mvc -f src\MyCompanyName.AbpZeroTemplate.Web.Mvc\Dockerfile .
This command will create a Docker image for the web application. Our application also needs to connect to a database. We will be using the *.Migrator project to create and seed our app's database. So, we need to create a docker image for our Migrator app as well. To do that, run the command below in the same directory (Don't forget to replace MyCompanyName.AbpZeroTemplate with your project name);
docker build -t abpzerotemplate-migrator -f src\MyCompanyName.AbpZeroTemplate.Migrator\Dockerfile .
Now, we have both Docker images we need to run our application.
Open a command prompt and go to "aspnet-core\etc\k8s\helm-chart" under your project directory and execute the Helm command below;
helm upgrade --install anz abpzerotemplate-mvc
This command will create 3 pods on Kubernetes, 1 for SQL Server, 1 for web application and 1 for the migrator app. The default Helm chart uses SQL Server but you can change it if your app uses a different database provider.
To access your app from your local computer, go to your Host file and add the entry below. You can use a different URL if you wish but don't forget to use that URL in the following steps.
127.0.0.1 abpzerotemplate-www
If you are not using Windows OS, you need to do the same for your OS.
Now, if you go to a browser and type https://abpzerotemplate-www, you can visit your published application.
Preparing ZAP for Testing
Open the OWASP ZAP application and load the script from "aspnet-core\etc\owasp\abpzerotemplate-mvc\abpzertemplate-mvc-login-script.zst" by clicking the scripts area and then load icon as shown below;
This script will be used to automatically login to the application as the Host user. After that, go to Sites section and load test context from "aspnet-core\etc\owasp\abpzerotemplate-mvc\abpzerotemplate-mvc.context" as shown below;
Sometimes, OWASP Tool doesn't load the context correctly, so check its important items as shown below;
Include Context
This section must contain the website URL which will be scanned;
Authentication
ZAP Tool will be use the Zest script we loaded above for login operation. So, it must be loaded correctly as shown below. If it is not set correctly, please load this script and set the fields marked in red as shown below;
Users
ZAP Tool requires a user to be defined for executing the login operation. So, a user must be defined as shown below;
Forced User
Finally, set the forced user as shown below;
Testing the App
Spider
To add your app to ZAP's Sites list, click on the Firefox icon on ZAP Tool and visit the https://abpzerotemplate-www on opened Firefox app. Then, right click on the your site and Click Attack > Spider as shown below;
Select the context we imported before and user we created/imported. This operation will find scan URLs in our application for testing with an authenticated user.
Test
Finally, we can start testing the app. To do that, right click on the your site and Click Attack > Active Scan and select the context we imported before and user we created/imported on the opened dialog and click "Start Scan" button.
Report
The test process might take a long time depending on the page count. When the test finishes, you can go to Report menu on ZAP Tool and generate a report as you wish.
