Definition
OpenVAS, or the Open Vulnerability Assessment System, is a comprehensive framework of open-source software designed for detecting security vulnerabilities in computer systems and networks. It operates by performing authenticated and unauthenticated scans to identify known weaknesses, misconfigurations, and potential security flaws. By systematically probing systems for these issues, OpenVAS helps organizations understand their attack surface and prioritize remediation efforts. For instance, a security analyst might use OpenVAS to scan a web server for outdated software versions or common injection vulnerabilities before they are exploited. Unlike a penetration test that actively attempts to exploit vulnerabilities, OpenVAS focuses on identification and reporting. This tool and its concepts are frequently encountered in cybersecurity certifications such as CompTIA Security+ and CySA+.
