What is Vulnerability assessment?

Understanding Vulnerability assessment

A systematic evaluation process of identifying vulnerabilities in cybersecurity systems without exploiting those vulnerabilities. A vulnerability assessment is a methodical review of security weaknesses in information systems networks infrastructure applications or other IT assets. It identifies and prioritizes vulnerabilities without actively exploiting them differentiating it from penetration testing. Assessments provide a snapshot of security posture and guide remediation efforts. Vulnerability assessment methodologies are defined in standards like NIST SP 800-115 ISO 27001 and various security testing frameworks. Organizations conduct vulnerability assessments through automated scanning tools manual review security baseline comparison and configuration analysis. For example a retail company might implement a vulnerability assessment program including quarterly scans of all internet-facing systems monthly scans of internal systems automated daily scans of critical applications security baseline compliance checking configuration validation and trending analysis to track security posture improvement over time providing a foundation for risk-based remediation.
