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
