Zero trust: what it means, what it isn't, where to start
What zero trust actually means, where it came from, and how to start: a practitioner's orientation to the model, the ecosystem, and the first moves.
Topic
Cybersecurity
Cybersecurity architecture is the practice of designing systems so that compromise is hard, contained, and recoverable. This section covers security architecture, defensive engineering, identity, segmentation, incident readiness, and securing emerging surfaces such as AI systems.
- Security architecture and design review
- Identity and access
- Defense in depth and segmentation
- Incident readiness and recovery
- AI and supply-chain security

Pillar Guide
Ransomware defense: a lifecycle map, not a product list
Ransomware defense mapped as a lifecycle — prevent, contain, survive, recover — and the engineering decisions at each stage that decide the outcome.
Articles & guides
Network Segmentation That Survives the Real World
How to design network segmentation an enterprise can operate: zone models, enforcement points, identity integration, and a migration path from flat networks.
Operational Resilience: Engineering Systems That Survive
Operational resilience as an engineered property: failure domains, degraded-mode design, tested RTO over dashboard uptime, and real failover discipline.
Zero Trust Architecture: What It Is and What It Isn't
Zero trust architecture explained by a practitioner: the policy decision model, identity as control plane, migration sequencing, and what it won't fix.
How I Run a Security Architecture Review (With Checklist)
A working security architecture review method: data-flow-first analysis, trust boundary mapping, the questions that expose real risk, and a usable checklist.
Incident Response From the Infrastructure Seat
Incident response for infrastructure teams: the preparation artifacts that matter, containment calls under pressure, and balancing evidence with recovery.
Identity Security: Defending the Perimeter You Actually Have
Identity security in practice: the tiered admin model, where MFA belongs, taming service accounts, conditional access, and surviving an IdP compromise.
Backup Security: Protecting the Last Line From Attackers
Backup security design for the era when attackers hunt backups first: isolation architectures, immutability options, air gaps, and restore testing that counts.
Architecture that survives ransomware
How to design for ransomware resilience: tiered identity, isolated and immutable backups, recovery-time engineering, and lessons from the ESXiArgs campaign.
