The Defensible Stack Audit: CodeVelo's October Security Checklist
The Defensible Stack Audit reviews trust, access lifecycle, containment, evidence, and recovery across infrastructure and software.
CodeVelo Journal
Operational clarity for the systems behind fast digital work.
Practical writing on infrastructure, web engineering, observability, automation, and the physical systems that keep software reliable.
Infra
Networks, power, physical resilience
Dev
Fast frontends and maintainable systems
Hybrid
Where hardware, workflows, and code meet
Service pillars
Read by operational problem
Infra
Physical systems that protect uptime
Network design, power planning, cabling, monitoring, recovery, and small business infrastructure hardening.
DevSoftware that stays fast under pressure
Frontend performance, delivery workflows, observability, progressive enhancement, and maintainable engineering practices.
HybridThe operating layer between code and hardware
Automation, audits, runbooks, digital twins, telemetry, and the handoff points where systems usually fail.

Recent field notes
Tabletop Exercises That Test Decisions, Not Theatre
Useful tabletop exercises expose decision gaps, authority conflicts, missing evidence, and untested recovery assumptions.
Security Logging Without Building a Surveillance System
Security logs should answer operational questions with the minimum personal data required and clearly controlled access.
Tamper Evidence for Racks, Cabling, and Edge Equipment
Tamper evidence helps teams detect and investigate physical changes without pretending that seals alone prevent access.
Authorization Drift: When Permissions Outlive Their Purpose
Authorization drifts when roles, grants, service accounts, and exceptions remain after the work that justified them ends.
Vendor Remote Access Without Permanent Trust
Vendor access should be named, scoped, approved, observed, time-limited, and removed when the work is complete.
Dependency Admission Policies for the Build Pipeline
Dependency admission policies evaluate source, maintenance, license, integrity, and risk before packages enter the trusted build path.
Securing Out-of-Band Management Before You Need It
Out-of-band management must remain isolated, attributable, and available when the production network cannot be trusted.
Secrets Have Lifecycles Too
Secrets should be requested, issued, scoped, delivered, observed, rotated, revoked, and destroyed through a controlled lifecycle.
