OpenVAS is widely recognized for its flexibility and effectiveness in identifying security weaknesses across different network environments. Its open-source nature makes it a valuable tool for both individual users and organizations aiming to enhance their security posture.
Before starting the installation process, ensure that your system is fully updated to avoid any compatibility issues during the setup.
In this guide, we'll walk you through the steps to install and configure OpenVAS on Kali Linux. From updating your system to running your first scan, you'll learn everything you need to get started with this essential security tool.
Preparing Your System
Before installing OpenVAS, it's important to ensure that your Kali Linux system is up to date. This step helps to prevent any issues related to outdated packages or dependencies during the installation process.
Update System Packages
Running system updates ensures that all software packages are current, which can help prevent compatibility issues.
sudo apt-get update sudo apt-get dist-upgrade
These commands will refresh your package lists and upgrade any outdated packages to their latest versions. It's a good practice to perform this step regularly to keep your system secure and running smoothly.
Installing OpenVAS
With your system updated, you're ready to install OpenVAS. This step involves downloading and setting up the OpenVAS software package on your Kali Linux system.
Install OpenVAS
Make sure to have a stable internet connection during the installation process to avoid interruptions.
sudo apt-get install openvas
This command will download and install the OpenVAS package along with its dependencies. The installation process might take a few minutes, depending on your internet speed and system performance.
Configuring OpenVAS
After installing OpenVAS, the next step is to configure it to ensure it’s ready for use. This involves running the setup script to initialize the OpenVAS environment.
Run Setup Script
Depending on your system configuration, you might need to install additional components like an SQLite database.
sudo gvm-setup
This command initiates the setup process for OpenVAS. During this process, you might be prompted to configure various settings and, in some cases, to install additional components such as SQLite if they are not already present on your system.
Starting OpenVAS Services
Once OpenVAS is configured, you'll need to start its services to begin using the tool. This step will activate the OpenVAS services on your Kali Linux system.
Start OpenVAS Service
Ensure that OpenVAS services are running to be able to access the web interface and perform scans.
sudo gvm-start
Running this command starts the OpenVAS services. It may take a few moments for the services to fully initialize. Once started, you’ll be able to access OpenVAS through your web browser and begin configuring your scans.
Troubleshooting Installation Issues
If you encounter any problems during or after the installation of OpenVAS, this section provides solutions for common issues that may arise. Ensuring all necessary services and dependencies are properly installed can resolve many problems.
Install and Start Required Services
Ensure that all services are running to avoid errors during setup or scanning.
sudo apt-get install postgresql sudo service postgresql start sudo apt-get install sqlite3 sudo service sqlite3 start sudo apt install gvm –y sudo gvm-feed-update
The commands above will install and start PostgreSQL and SQLite3, which are often required for OpenVAS. Additionally, running sudo gvm-feed-update will ensure that the OpenVAS feed is up-to-date with the latest vulnerability data.
Accessing OpenVAS Web Interface
With OpenVAS installed and running, you can now access its web interface to manage vulnerabilities and perform scans. This section will guide you on how to navigate to the OpenVAS web UI and log in using your credentials.
Open Web UI
Ensure your browser allows access to local addresses to view the OpenVAS web interface.
To access the OpenVAS web interface, open your web browser and navigate to the following URL:
[http://localhost:9392](http://localhost:9392)
Log in using the username admin and the password generated during the setup process. This will take you to the OpenVAS dashboard where you can begin configuring your scans and managing targets.
Using OpenVAS
Now that OpenVAS is set up and running, you can start using it to perform security scans and manage targets. This section covers the basic tasks you need to know to effectively use OpenVAS.
Add a Target
Defining targets is crucial for scanning specific devices or IP ranges within your network.
To add a target for scanning:
- Navigate to the Configuration menu and select Targets.
- Click the blue icon to enter the details for the new target.
Create a Scan Task
Creating tasks allows you to schedule and perform scans on defined targets.
To create a new scan task:
- Navigate to Scans and select Tasks.
- Click the left-hand icon to create a new task.
- Provide the necessary details for the scan task and click Create.
Run a Scan Task
Running the scan task will initiate the vulnerability assessment on your selected targets.
To start a scan task:
- Locate the task in the task list.
- Click the Play icon at the bottom left of the task list.
Add Users
Adding users can help manage access and permissions within OpenVAS.
To add new users:
- Navigate to Administration and click on Users.
- Select the Add New icon and enter the user information.
