Chapters¶

Nexus SecOps comprises 58 chapters organized into 7 parts. Each chapter is a hand-rewritten reference: opinionated, named recommendations, specific failure modes, no filler.

Part I -- Foundations (Ch 1-6)¶

The everyday SOC: telemetry, normalization, SIEM, detection engineering, triage, and threat intelligence. Start here if you are new to security operations.

Part II -- Automation, AI, and Operating Model (Ch 7-15)¶

SOAR done honestly, IR lifecycle, AI/ML in the SOC (and where it doesn't fit), LLM copilots and guardrails, compliance/privacy/AI-risk, threat modeling integration, operating model and SLAs, gamification.

Part III -- Architecture and Cryptography (Ch 16-22)¶

Penetration testing program design, network security architecture, applied cryptography, identity and access security, cloud attack and defense, container security.

Part IV -- Specializations and Sector Domains (Ch 23-29)¶

Mobile security, OT/ICS, malware analysis foundations, advanced incident response, threat hunting, deception, advanced threat hunting playbooks.

Part V -- Operations Engineering (Ch 30-37)¶

Method¶

All 58 chapters were rewritten by hand between sessions 36-43 against scripts/voice_quality_check.py. Average score 8 (target <50). Original ~58,500 lines reduced to ~12,650 (~78% reduction). Bias was always toward the named tool with the honest tradeoff over the comprehensive-sounding survey.
