# Performing Authenticated Scan with OpenVAS ## Overview OpenVAS (Open Vulnerability Assessment Scanner) is the scanner component of the Greenbone Vulnerability Management (GVM) framework. Authenticated scans use valid credentials (SSH for Linux, SMB for Windows, ESXi for VMware) to log into target systems, enabling detection of local vulnerabilities, missing patches, and misconfigurations that unauthenticated scans cannot identify. Authenticated scans typically find 10-50x more vulnerabilities than unauthenticated scans. ## When to Use - When conducting security assessments that involve performing authenticated scan with openvas - When following incident response procedures for related security events - When performing scheduled security testing or auditing activities - When validating security controls through hands-on testing ## Prerequisites - GVM 22.x+ installed (gvmd, openvas-scanner, gsad, ospd-openvas) - PostgreSQL database configured for gvmd - Redis configured for openvas-scanner - NVT feed synchronized (greenbone-nvt-sync or greenbone-feed-sync) - SSH credentials for Linux targets or SMB credentials for Windows targets - Network access to target hosts on scan ports ## Installation ### Install GVM on Kali Linux / Debian ```bash # Install GVM package sudo apt update && sudo apt install -y gvm # Run initial setup (creates admin account, syncs feeds) sudo gvm-setup # Check installation status sudo gvm-check-setup # Start all GVM services sudo gvm-start # A...
