Vulnerability Management

Every security team inherits the same problem: a scanner that never stops finding things, a spreadsheet that never stops growing, and a patch queue that grows faster than anyone can work it. Vulnerability Management: From Scanning to Risk-Based Remediation is the practical, end-to-end guide for security engineers, analysts, and managers who are ready to replace the "patch everything" instinct with a defensible, risk-driven program.

This book walks the full lifecycle of a modern vulnerability management program, from asset discovery and scanning through risk-based prioritization, remediation workflows, cloud and container security, application vulnerability management, and zero-day emergency response. You'll learn how to combine CVSS, EPSS, and CISA's KEV catalog into a scoring formula that actually reflects real-world risk, how to build an SLA matrix by severity and asset class, how to structure a defensible exception process, and how to run a patch ring deployment strategy that keeps your fleet current without causing outages.

The book doesn't stop at theory. It includes concrete, ready-to-adapt artifacts: an exception request template, a sample prioritization scoring formula with worked examples, a patch ring strategy document, and a full case study tracing Log4Shell from disclosure to verified remediation, showing exactly where most programs fail and how to avoid it.

Whether you're standing up a program from scratch or trying to mature an existing one, this book gives you the vocabulary, the workflows, and the operating model to turn scanner output into a measurable reduction in real exposure, not just a shorter spreadsheet.
