What is Vulnerability Management?
Vulnerability management is the continuous process of identifying, classifying, prioritizing, remediating, and verifying security weaknesses in systems and software, reducing the exploitable attack surface before adversaries can leverage known flaws.

How Vulnerability Management Works
A mature program runs a continuous cycle: discovery (automated scanning with Tenable Nessus, Qualys, or Rapid7 InsightVM), assessment (distinguishing real vulnerabilities from false positives, assessing exploitability), prioritization (risk-ranking by CVSS score, exploitability, asset criticality, and compensating controls), remediation (patches, configuration changes, mitigations), and verification (re-scanning to confirm fixes).
Prioritization is the hardest challenge. Organizations have thousands of open vulnerabilities at any time. Risk-based prioritization considers: CVSS base score, temporal score (public exploits exist?), EPSS (probability of exploitation in 30 days), asset criticality (internet-facing? stores sensitive data?), and compensating controls (vulnerable port blocked at firewall?).
Vulnerability management integrates with patch management (applying fixes) and asset management (accurate inventory of what to scan).
Vulnerability Management in SOC Operations
You use vulnerability data as context for alert prioritization. An exploit attempt against a known-vulnerable, internet-facing, unpatched system is a critical alert. When a new zero-day drops, SOC teams conduct emergency scanning, implement temporary mitigations (WAF rules, network blocks), and track remediation. Vulnerability data in the SIEM enables correlation rules that fire when exploit attempts target confirmed-vulnerable hosts.
