Sanitized Case Study
NodeZero
A systems case study spanning Linux, containers, service boundaries, security posture, documentation, and recovery thinking. Operational details stay private.
Positioning
Owner-Produced Documentation of a Real System
NodeZero is a self-hosted Debian-based Linux environment. The public account covers how the system was documented and assessed; topology and operational evidence remain private.
Overview
System Scope & Goals
Goals
Document a running self-hosted environment honestly: services, boundaries, posture, and recovery readiness.
Architecture
Linux host with containerized services behind explicit service boundaries, with configuration and documentation discipline.
Engineering Decisions
Segmentation, secure configuration baselines, and recovery thinking treated as first-class engineering work.
Methodology
Evidence before claims. The case study reports what the material supports: documented services, observed posture, and gaps — without exposing operational detail.
Document services
Inventory active container services and network boundaries.
Assess boundaries
Review service isolation, access controls, and exposure.
Review posture
Evaluate configuration baselines, patch state, and risk factors.
Plan recovery
Define disaster recovery protocols, backup frequency, and restoration readiness.
Status & Boundaries
NodeZero is a sanitized case study. Network topology, live operational evidence, and internal service detail are intentionally excluded from this page and its build data.
