Applied Cybersecurity Practices: Practical Principles for Assessing Risks, Protecting Systems, and Responding to Security Threats

By Thom Haagenrud

Build a cybersecurity program that works in the real world-not just on paper.

Cybersecurity is more than firewalls, scanners, encryption, and alerts. Strong defense comes from knowing what matters, understanding how failures can occur, choosing controls that reduce meaningful exposure, and being prepared when prevention fails.

Applied Cybersecurity Practices takes a practical, risk-based approach to defensive security for students, IT professionals, administrators, security practitioners, and technical leaders who need to turn cybersecurity concepts into repeatable operational practices.

Inside, you'll learn how to:

- Identify critical assets, threats, vulnerabilities, and business risks
- Build practical risk registers and prioritize remediation beyond severity scores
- Establish governance, policies, standards, controls, and accountability
- Strengthen identity, authentication, privileged access, and least-privilege models
- Harden endpoints, manage vulnerabilities, patch effectively, and reduce exposure
- Design network segmentation and apply zero-trust principles
- Protect sensitive data through access controls, encryption, backup, and recovery testing
- Build useful logging, monitoring, detection, and security metrics
- Defend against phishing, social engineering, account compromise, and human-centered risks
- Address cloud configuration, application security, software supply-chain, and secrets-management risks
- Prepare for incidents through triage, containment, evidence preservation, recovery, and lessons learned
- Assess control effectiveness and create measurable improvement plans

This book goes beyond theory with practical scenarios, exercises, templates, checklists, tabletop workshops, and a 90-day cybersecurity improvement program. The exercises are designed to build operational confidence: identify what matters, reason about risk, select proportionate controls, interpret evidence, document decisions, and improve continuously.

Whether you're entering the field, moving from IT into security, managing infrastructure or cloud workloads, or leading a technical team, this book provides a structured way to connect governance, protection, detection, response, recovery, and continuous improvement.

The goal isn't perfect security. It's informed, defensible, resilient security practice.
