Vulnerability Assessment

A vulnerability assessment is an automated process of identifying security weaknesses in systems, networks, and applications without actively exploiting them.

Vulnerability assessments systematically identify security weaknesses in IT systems. Unlike penetration testing, they focus on discovery and classification without exploitation.

Types of assessments: - Network Scanning: Identifying vulnerable services - Web Application Scanning: Finding web vulnerabilities (OWASP Top 10) - Database Scanning: Checking database configurations - Host-Based Assessment: Evaluating system configurations - Cloud Configuration Review: Assessing cloud settings

Common tools: - Nessus, Qualys, Rapid7 (network) - OWASP ZAP, Burp Suite (web) - AWS Security Hub, GCP Security Command Center (cloud)

Vulnerabilities are scored using CVSS (0-10 scale), with 7+ considered high severity.

Why It Matters

Vulnerability assessments provide continuous visibility into your attack surface, identifying weaknesses before attackers do. Compliance frameworks require regular vulnerability scanning—typically quarterly—with documented remediation timelines. Organizations that run continuous scans and remediate critical vulnerabilities within 14 days significantly reduce their breach risk compared to those relying on annual assessments.

Key Points

Identifies vulnerabilities without exploiting them

Should be performed at least quarterly

CVSS scoring helps prioritize remediation

Automated scans need expert analysis

Different from pen testing which involves exploitation

Applicable Compliance Frameworks

SOC 2 ISO 27001 HIPAA PCI DSS NIST CSF

Penetration Testing

Penetration testing is a simulated cyberattack on your systems performed by security professionals to identify exploitable vulnerabilities.

Risk Assessment

A risk assessment is a systematic process of identifying, analyzing, and evaluating potential threats to an organization's information assets.

Patch Management

Patch management is the process of acquiring, testing, and deploying software updates to fix vulnerabilities, improve functionality, and ensure system security.
