OpenVAS Vulnerability Scanner by Hacker Target is a comprehensive vulnerability assessment system that detects security issues in servers and network devices. It is a hosted version of the OpenVAS software designed to test Internet infrastructure. OpenVAS Vulnerability Scanner analyzes open network services for security vulnerabilities using a database of over 20,000 known vulnerabilities. It initially conducts a port scan to find open services, then tests these services for known vulnerabilities and misconfigurations using a database of over 53,000 NVT checks. The results are compiled into a report with detailed information on each vulnerability and notable issues. OpenVAS Vulnerability Scanner is configured to run using the 'Full and Fast Scan' profile.
