# Performing Authenticated Vulnerability Scan ## Overview Authenticated (credentialed) vulnerability scanning uses valid system credentials to log into target hosts and perform deep inspection of installed software, patches, configurations, and security settings. Compared to unauthenticated scanning, credentialed scans detect 45-60% more vulnerabilities with significantly fewer false positives because they can directly query installed packages, registry keys, and file system contents. ## When to Use - When conducting security assessments that involve performing authenticated vulnerability scan - 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 - Vulnerability scanner (Nessus, Qualys, OpenVAS, Rapid7 InsightVM) - Service accounts with appropriate privileges on target systems - Secure credential storage (vault integration preferred) - Network access from scanner to target management ports - Written authorization from system owners ## Core Concepts ### Why Authenticated Scanning Unauthenticated scanning can only assess externally visible services and banners, often leading to: - Missed vulnerabilities in locally installed software - Inaccurate version detection from banner changes - Inability to check patch levels, configurations, or local policies - Higher false positive rates due to inference-based detec...
