How Does OpenVAS Work?

Using OpenVAS for vulnerability assessment open source tasks is simple, even for beginners. Here’s a step-by-step guide to get you started:

1. Install OpenVAS: Download and install OpenVAS on a Linux system like Ubuntu. The official website (www.openvas.org) provides detailed instructions.
2. Set Up Your Scan: Add your target—such as a website URL, internal IP address, or even a wireless network for wifi scanner purposes—and select a scan type (e.g., full scan or web-specific scan).
3. Run the Scan: OpenVAS uses its extensive database to check for vulnerabilities like outdated software, open ports, or risks to data privacy that could expose sensitive information.
4. Review the Report: After the scan, you’ll get a detailed report with actionable steps, such as updating a plugin or securing a server, making it an effective website scanner for your online presence.

For example, if you’re using OpenVAS as a website vulnerability scanner, you can input your site’s URL, choose a web-focused scan profile, and quickly identify risks like SQL injection vulnerabilities. It also doubles as a web scanner, ensuring your online assets are free from hidden threats.

Use Cases

OpenVAS is versatile and can be applied in various scenarios, especially for small businesses:

• Website Security: A small e-commerce store used OpenVAS as a website scanner to find an outdated plugin that could have led to a data breach. Fixing it saved them from potential fines and customer loss, while also acting as a website checker to ensure ongoing safety.
• Network Protection: A startup with a small IT team used OpenVAS for open source vulnerability management, scanning their internal servers and wireless networks with its wifi scanner capabilities to ensure no open ports were exposed to hackers.
