Talos Linux removes SSH, the shell, and mutable state from Kubernetes nodes entirely. Here's how it works, how it compares to Flatcar, Bottlerocket, and Fedora CoreOS, and why it's changing how serious teams run Kubernetes in production.
A principal cloud architect's guide to detecting leaked credentials in git history, CI logs, and container images using Gitleaks, TruffleHog, and GitGuardian. Includes pre-commit setup, CI integration, and how to handle the scary historical scan.
Most container images are unnecessarily bloated and packed with vulnerabilities that will never get patched. Here's how to use distroless images, Chainguard, and multi-stage builds to shrink your attack surface to what actually matters.
How to build a certificate management system that doesn't wake you up at 3am. cert-manager, Vault PKI, Smallstep, CA hierarchy design, short-lived certs, and the operational patterns that prevent certificate-expiry cascades.
gVisor and Kata Containers solve the isolation problem containers were never designed to solve. Here is how to sandbox untrusted workloads in Kubernetes before a kernel exploit does it for you.
Non-human identities now outnumber human identities 45-to-1 in modern enterprises. Service accounts, API keys, OAuth tokens, and AI agent credentials are proliferating faster than anyone can track. Here is how to govern them before they become your next breach.
SPIFFE and SPIRE give every workload a cryptographic identity without static secrets. Learn how the standard works, how to deploy it in production, and why it's the missing piece in most zero-trust architectures.
A principal cloud architect breaks down DNSSEC, DNS over HTTPS, DNS over TLS, and the real-world attacks that exploit unprotected DNS infrastructure.
A practical guide to migrating cloud infrastructure to post-quantum cryptography. Covers NIST ML-KEM and ML-DSA standards, hybrid TLS deployment, PKI migration, and a phased roadmap for engineering teams facing real 2026 compliance deadlines.
A deep-dive into Firecracker, the open-source microVM technology that powers AWS Lambda, Fargate, and Bedrock AgentCore. Learn how it balances security isolation with serverless performance.
AI agents face a new class of security threat that breaks every assumption from traditional application security. A principal cloud architect's guide to prompt injection defense, tool access controls, output filtering, and the layered guardrails architecture that actually protects production AI systems.
CNAPP converges CSPM, CWPP, and CIEM into a single security platform covering your entire cloud attack surface. Here's what it actually covers, how the major vendors compare, and what to look for when you evaluate one.
Stop putting AWS access keys in environment variables. Workload Identity Federation via OIDC (IRSA on EKS, GKE Workload Identity, Azure Workload Identity) eliminates static credentials from your services entirely. Here is how it works and how to migrate.
Static image scanning isn't enough. Container runtime security with Falco, seccomp profiles, and AppArmor catches threats that image scanners miss. Here's how to implement it.
A practical guide to Kubernetes RBAC: how Roles, ClusterRoles, RoleBindings, and ServiceAccounts work, common misconfigurations that get teams compromised, and how to design least-privilege access that survives contact with your developers.
Learn how confidential computing and trusted execution environments (TEEs) protect data while it's being processed, with practical guidance on Intel SGX, AMD SEV, and cloud provider implementations.
RBAC breaks down at scale. Learn how Google Zanzibar's relationship-based model works, how OpenFGA and SpiceDB implement it, and when your app needs a dedicated authorization service.
A practitioner's guide to security groups and network ACLs in cloud environments, covering how each works, key differences, and how to layer them for defense in depth.
Practical deep dives on infrastructure, security, and scaling. No spam, no fluff.
