OpenVAS installation from sources for Kali Linux (rolling-release) systems.

This script automates the installation and configuration of OpenVAS (Greenbone Community Edition) from source on Debian 12 systems. It follows the Greenbone Community Edition guidelines to set up a secure and fully functional vulnerability scanning environment, adhering to principles of secure-by-design, least privilege, and defense-in-depth.

Description

The openvas_install.sh script installs OpenVAS and its dependencies, configures required system services (Redis, PostgreSQL), and sets up the Greenbone Security Assistant (GSA) web interface. Key features include:

• Automatic fetching of the latest component versions from GitHub.
• Structured logging with INFO, WARN, and ERROR levels.
• GPG signature verification for source packages.
• Creation of a dedicated gvm user and group for running services.
• Generation of self-signed SSL certificates for secure web access.
• Configuration of systemd services for OpenVAS components.
• Setup of feed synchronization and PostgreSQL database for vulnerability data.
• Secure permission settings.

Usage

1. Prerequisites:

• A clean, fully updated Kali Linux system with internet access.
• Root privileges (the script must be run as root).
• At least 1GB of free disk space in $HOME/source, $HOME/build, and $HOME/install directories.

2. Login as root:

sudo su

3. Download the Script:

curl -f -L https://raw.githubusercontent.com/Kastervo/OpenVAS-Installation/master/openvas_install.sh -o openvas_install.sh

4. Make the Script Executable:

chmod +x openvas_install.sh

5. Run the Script:

./openvas_install.sh

6. Access the Web Interface:

• After successful execution, the script outputs login details (username: admin, password, and URL).
• Access the OpenVAS web interface at https://<host_ip>:9392.
• For security, change the admin password using:

/usr/local/sbin/gvmd --user=admin --new-password=<new_strong_password>

Make sure the TCP port 9392 is open on your firewall.

7. Logs:

Installation logs are stored in /var/log/openvas_install.log for troubleshooting.

Note: Replace the self-signed SSL certificate with a trusted one for production environments. Ensure network connectivity to GitHub and Greenbone servers for version checks and feed synchronization.

Troubleshooting

Verify the services are running without errors:

sudo systemctl status ospd-openvas
sudo systemctl status gsad
sudo systemctl status gvmd
sudo systemctl status openvasd

Update the Openvas feeds:

/usr/local/bin/greenbone-feed-sync

Create a user:

/usr/local/sbin/gvmd --create-user=<username>

Reset a user password:

/usr/local/sbin/gvmd --user=<username> --new-password=<password>

Setting the Feed Import Owner:

/usr/local/sbin/gvmd --modify-setting 78eceaec-3385-11ea-b237-28d24461215b --value `/usr/local/sbin/gvmd --get-users --verbose | grep admin | awk '{print $2}'`
