Chapter 11 Further Reading: Vulnerability Assessment

Essential Books

"The Art of Software Security Assessment" by Mark Dowd, John McDonald, and Justin Schuh (Addison-Wesley, 2006) While focused on code-level assessment, this remains one of the most rigorous treatments of vulnerability identification ever published. It teaches the analytical mindset required to understand why vulnerabilities exist, which deepens your ability to validate scanner findings.

"Tribe of Hackers: Red Team" by Marcus J. Carey and Jennifer Jin (Wiley, 2019) A collection of interviews with leading red team and vulnerability assessment professionals discussing their methodologies, career paths, and lessons learned. Valuable for understanding how experienced practitioners approach assessment in diverse environments.

"Hacking Exposed 7" by Stuart McClure, Joel Scambray, and George Kurtz (McGraw-Hill, 2012) A classic reference that systematically catalogs vulnerability categories and assessment techniques across network, system, and application layers. While some specific tools have evolved, the assessment methodology remains relevant.

"The Web Application Hacker's Handbook" by Dafydd Stuttard and Marcus Pinto (Wiley, 2nd Edition, 2011) The definitive guide to web application vulnerability assessment. Covers methodology for identifying injection, authentication, session management, and access control vulnerabilities through both automated and manual testing.

"Practical Vulnerability Management" by Andrew Magnusson (No Starch Press, 2020) Bridges the gap between assessment and management. Covers vulnerability scanning, prioritization, remediation tracking, and program maturity — essential reading for professionals responsible for ongoing vulnerability management programs.

Standards and Frameworks

NIST SP 800-115: Technical Guide to Information Security Testing and Assessment The official NIST guide covering vulnerability scanning methodology, assessment planning, and result analysis. Freely available at csrc.nist.gov. Provides the authoritative framework for federal vulnerability assessments and is widely adopted in the private sector.

PTES: Penetration Testing Execution Standard — pentest-standard.org The PTES defines the vulnerability analysis phase of penetration testing, including active and passive testing, validation, and research. It provides a structured methodology that aligns vulnerability assessment with the broader pentest lifecycle.

OWASP Testing Guide v4.2 — owasp.org/www-project-web-security-testing-guide/ The most comprehensive guide to web application vulnerability assessment, with detailed test cases for every category of web vulnerability. Essential for any assessment involving web applications.

OWASP Risk Rating Methodology — owasp.org/www-community/OWASP_Risk_Rating_Methodology A detailed framework for rating vulnerability risk that goes beyond CVSS to incorporate threat agent factors and business impact. Useful for developing risk-adjusted prioritization methodologies.

CVE, CVSS, and Vulnerability Intelligence

National Vulnerability Database (NVD) — nvd.nist.gov The primary source for CVE enrichment data, CVSS scores, CPE configurations, and CWE classifications. The NVD API enables programmatic access for integrating vulnerability data into assessment tools and dashboards.

FIRST CVSS Calculator — first.org/cvss/calculator/3.1 The official CVSS v3.1 calculator from FIRST (Forum of Incident Response and Security Teams). Essential for understanding and manually calculating CVSS scores. Also hosts the CVSS v4.0 calculator for those transitioning to the latest standard.

CVSS v4.0 Specification — first.org/cvss/v4-0/ The latest version of the Common Vulnerability Scoring System, released in late 2023. Introduces refinements including additional metrics for Supplemental and Environmental considerations. Important for professionals preparing for the industry transition from v3.1 to v4.0.

CISA Known Exploited Vulnerabilities Catalog — cisa.gov/known-exploited-vulnerabilities-catalog A curated, continuously updated list of vulnerabilities known to be actively exploited in the wild. Any vulnerability on this list warrants immediate prioritization. The catalog is available as an API feed for integration into vulnerability management platforms.

Exploit Database — exploit-db.com The Offensive Security-maintained repository of public exploits. Cross-referencing scanner findings against Exploit-DB reveals which vulnerabilities have available proof-of-concept code, significantly affecting prioritization.

VulnCheck — vulncheck.com A modern vulnerability intelligence platform that provides enriched vulnerability data including exploit intelligence, EPSS (Exploit Prediction Scoring System) scores, and comprehensive reference linking. The EPSS model predicts the likelihood that a vulnerability will be exploited in the wild within 30 days.

Research Papers and Reports

"The Equifax Data Breach" — U.S. Government Accountability Office (GAO-18-559) The official GAO report on the Equifax breach, providing detailed analysis of the vulnerability management failures that led to the compromise. Essential reading for understanding the consequences of assessment failures.

"Log4Shell: A Retrospective" — CISA and CSRB (Cyber Safety Review Board), July 2022 The Cyber Safety Review Board's comprehensive analysis of the Log4Shell vulnerability and response. Includes recommendations for improving organizational vulnerability response capabilities.

"Prioritizing Vulnerability Remediation" — Carnegie Mellon SEI Blog Research from the Software Engineering Institute on evidence-based vulnerability prioritization, including the SSVC (Stakeholder-Specific Vulnerability Categorization) framework that provides an alternative to CVSS for prioritization decisions.

Tools and Platforms

FIRST EPSS — first.org/epss/ The Exploit Prediction Scoring System uses machine learning to predict the probability that a vulnerability will be exploited in the wild. EPSS scores complement CVSS by adding an empirical exploitability dimension to prioritization.

Tenable Nessus Documentation — docs.tenable.com/nessus/ Comprehensive documentation for the industry-leading commercial vulnerability scanner. Covers scan configuration, plugin development, credentialed scanning, and integration with vulnerability management platforms.

Greenbone OpenVAS Documentation — greenbone.github.io/docs/ Documentation for the leading open-source vulnerability scanner. Includes installation, configuration, and scan management guides.

Nuclei Templates Repository — github.com/projectdiscovery/nuclei-templates Over 8,000 community-contributed vulnerability detection templates. Studying these templates teaches both vulnerability patterns and detection techniques.

Vulners — vulners.com A comprehensive vulnerability intelligence search engine that aggregates data from CVE, NVD, Exploit-DB, and dozens of vendor advisories. Useful for rapid vulnerability research during assessments.
