Cyber Security Essentials

Every security control an organization buys is, in the end, an instrument that has to be played. SOC Operations: Running an Effective Security Operations Center is the practitioner's guide to playing it well.

This book walks aspiring and current SOC analysts, team leads, and managers through the twelve areas that determine whether a SOC actually reduces risk: mission and operating models, roles and tiers, the SIEM/XDR/SOAR technology stack, log onboarding, alert triage, detection engineering, tuning, automation, shift operations, metrics, working with adjacent teams, and building and maturing the function over time.

This isn't a theory book. Every chapter pairs concepts with artifacts you can use immediately: Sigma and KQL detection examples you can adapt to your own environment, a full triage checklist, a shift handoff template, an escalation matrix, a metrics dashboard description, and a complete worked phishing incident traced from ingestion to closure.

Three principles run through the book: process precedes technology, detection is a software engineering discipline, and automation is a force multiplier, not a substitute for analysts. Whether you're triaging your first alert or building a SOC roadmap for the year ahead, this book gives you the patterns that work.

CSIRT Operations is a working handbook for security managers, team leads, and senior analysts who have been asked to stand up, mature, or rationalize a Computer Security Incident Response Team. It assumes you already understand networks, endpoints, malware, and basic detection concepts, but have never had to write a charter, fight for headcount, design an on call rotation, defend a budget, run a war room, or sit across the table from a regulator.

Across twelve chapters, you'll learn how to define a constituency, choose an organizational model, build a service catalog grounded in the FIRST CSIRT Services Framework, structure and staff a team, write policy and playbooks aligned to NIST SP 800-61 Rev. 3 and ISO/IEC 27035, design the tooling stack, run the incident handling workflow, coordinate externally using TLP 2.0, manage major incidents, exercise the team, measure what matters, and roadmap growth toward threat hunting and intelligence.

Every chapter ships with practical, ready to adapt artifacts: charter outlines, service catalogs, skills matrices, on call schedules, severity matrices, executive briefing templates, a full tabletop scenario, and a worked example of standing up a CSIRT in a mid size company from charter to first major incident.

The literature on incident response is full of breach postmortems and tool reviews. This book is different. It's for the people who have to defend a budget, hire a forensic lead, write a charter the general counsel will actually sign, and run a tabletop that doesn't waste everyone's afternoon, and who would like to do those things well the first time.

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.
