Agent, Scan or Beyond: Modern Methods for Comprehensive Infrastructure Vulnerability Scanning
The eighth installment in the Vulnerability Management for Beginners series explains why traditional scanning approaches no longer cover today's dynamic environments. It details three classic methods—Host Discovery, Pentest, and Audit—alongside agent-based scanning, cloud snapshot techniques, passive traffic analysis, container and SCA tools, and integrations with existing IT systems. The guide stresses that agents from Tenable and Qualys complement but do not replace network scanning, while Orca Security and Wiz pioneered disk snapshot analysis for short-lived cloud instances. It also covers container image scanning with Trivy and Grype before deployment, passive monitoring for OT environments, and the importance of combining multiple data sources to eliminate blind spots. Practical recommendations include scanning frequency by asset type and six post-scan steps for effective remediation.
