# Defectdojo for Pentesters

## Section 1: Installation and Configuration on Kali Linux

### Introduction to Defectdojo

Defectdojo is an open-source application vulnerability management tool that allows pentesters to manage security findings in a centralized manner. It serves as a bridge between vulnerabilities discovered during testing and the development lifecycle, enabling teams to prioritize and resolve issues effectively. In this section, we will delve into the installation, configuration, and practical use cases of Defectdojo on Kali Linux.

### Prerequisites

Before we start with the installation, ensure you have the following prerequisites:

– A Kali Linux installation (preferably the latest version)
– Basic understanding of Linux command line
– Docker installed and running (for containerized installation)
– Python 3.x (if opting for a non-Docker installation)

### Installation

#### Step 1: Installing Docker

Defectdojo can be easily deployed using Docker, which simplifies the installation process. If you haven't installed Docker yet, you can do so by following these commands:

"`bash
sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add –
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce
"`

After installation, ensure that Docker is running:

"`bash
sudo systemctl start docker
sudo systemctl enable docker
"`

#### Step 2: Pulling the Defectdojo Image

Now that Docker is installed, we’ll pull the Defectdojo Docker image:

"`bash
docker pull defectdojo/defectdojo-django
"`

#### Step 3: Running Defectdojo

You can run Defectdojo using the following Docker command:

"`bash
docker run -d -p 8000:8080 defectdojo/defectdojo-django
"`

This command maps port 8000 on your host to port 8080 in the container where Defectdojo runs. You can access Defectdojo by navigating to [http://localhost:8000](http://localhost:8000) in your web browser.

#### Step 4: Initial Configuration

After accessing the web application, you will need to configure the initial settings:

1. **Create an Admin User**: You’ll be prompted to create an admin user during the first-time setup. Fill in the required fields such as username, email, and password.

2. **Configure Settings**: After logging in, navigate to the settings area to configure items such as integrations with CI/CD tools, email notifications, and more.

### Step-by-Step Usage

Once you have Defectdojo up and running, let’s explore how to use it effectively for pentesting purposes.

#### Step 1: Creating a New Engagement

1. **Log in to Defectdojo**: Open your browser and access [http://localhost:8000](http://localhost:8000).
2. **Navigate to Engagements**: Click on “Engagements” in the main menu.
3. **Create New Engagement**: Click on the “Add Engagement” button. Fill in details such as Name, Description, and Type (e.g., Pentest, Audit).
4. **Engagement Dates**: Set the start and end dates for the engagement.

#### Step 2: Importing Findings

You can import findings from various tools like OWASP ZAP, Nmap, Burp Suite, etc. Here is an example of how to import findings from an OWASP ZAP report.

"`bash
# Assuming you have an OWASP ZAP report in JSON format

curl -X POST http://localhost:8000/api/v2/import_zap/
-H "Authorization: Token "
-F "engagement="
-F "file=@path_to_zap_report.json"
"`

Replace `` with your Defectdojo API token and `` with the ID of your engagement.

#### Step 3: Managing Findings

After importing the findings, you can manage them as follows:

1. **View Findings**: Click on “Findings” in the main menu. This will display a list of all imported findings.
2. **Filter Findings**: Use the filters to narrow down the results based on severity, status, etc.
3. **Edit Findings**: Click on a finding to view its details. You can edit its status, assign it to a team member, and add notes.

### Real-World Use Cases

#### Use Case 1: Continuous Integration/Continuous Deployment (CI/CD) Integration

Defectdojo can be integrated with CI/CD pipelines to automate vulnerability management. For instance, you can use a webhook to trigger Defectdojo when a new build is created in Jenkins.

Example Jenkins Pipeline Snippet:

"`groovy
pipeline {
agent any
stages {
stage('Build') {
steps {
// Build steps here
}
}
stage('Test') {
steps {
script {
// Trigger OWASP ZAP scan and generate report
sh 'zap.sh -quickurl http://your-app -quickout zap_report.json'
}
}
}
stage('Upload Findings') {
steps {
script {
// Upload findings to Defectdojo
sh "'
curl -X POST http:///api/v2/import_zap/
-H "Authorization: Token "
-F "engagement="
-F "file=@zap_report.json"
"'
}
}
}
}
}
"`

#### Use Case 2: Vulnerability Tracking and Reporting

Defectdojo provides robust reporting features that can be utilized to keep stakeholders informed about the security posture of the application. You can generate reports in multiple formats such as PDF, HTML, etc.

To generate a report, navigate to the “Reports” section, choose the desired report type, select the engagement, and click on “Generate Report”.

### Detailed Technical Explanations

Defectdojo allows you to customize it according to your specific needs. Here are key areas you might want to explore:

1. **API Usage**: Defectdojo has a comprehensive REST API that allows you to automate tasks such as imports, exports, and finding management. You can access the API documentation here: [Defectdojo API Documentation](https://defectdojo.readthedocs.io/en/latest/api.html).

2. **Webhooks**: Utilize webhooks to connect Defectdojo with other tools. This is particularly useful for automating notifications or updates when findings are created or modified.

3. **User Roles and Permissions**: Manage who can access what within Defectdojo through customized roles and permissions.

4. **Integrations**: Explore integrations with tools such as Jira, Slack, and others to streamline communication and workflow.

### Example Code in Markdown

For the convenience of documenting your process, here's a sample markdown snippet you might include in your WordPress posts or documentation:

"`markdown
# Import Findings to Defectdojo

To import findings from OWASP ZAP, use the following curl command:

"`bash
curl -X POST http://localhost:8000/api/v2/import_zap/
-H "Authorization: Token "
-F "engagement="
-F "file=@path_to_zap_report.json"
"`
"`

### Conclusion

In this section, we covered the installation and configuration of Defectdojo on Kali Linux, along with step-by-step usage scenarios and real-world applications of the tool. By effectively utilizing Defectdojo, pentesters can manage vulnerabilities efficiently and contribute towards improving the security posture of applications.
