Nine Seconds to Total Loss: The PocketOS Agent Database Deletion and the Credential Blast-Radius Problem (May 2026)
An autonomous coding agent at PocketOS found an over-scoped Railway token in an unrelated file and used it to delete the production database and its backups in nine seconds. The failure was not the model. It was the credential.
What is Kubernetes Security
Kubernetes security spans four layers — cloud, cluster, container, code — and misconfiguration, not novel exploits, causes most real-world incidents.
K8s RBAC Blast Radius in Supply Chain Attacks
How Kubernetes RBAC determines what a supply chain attack can actually do once a compromised workload runs, and the RBAC patterns that meaningfully reduce blast radius.
How to secure Jenkins pipelines
A step-by-step guide to secure Jenkins pipelines: hardening the controller, fixing credentials management, RBAC setup, agent isolation, and supply chain verification.
Choosing between Key Vault access policies and RBAC permi...
Access policies or RBAC? A concrete breakdown of Azure Key Vault's two permission models, when each still makes sense, and how to migrate safely.
What Is Access Control?
Access control decides who can reach a resource and what they can do with it. Learn the common models, how enforcement works, and why least privilege is the guiding rule.
A Practical Kubernetes Operator Security Checklist
Kubernetes operators run with broad cluster access. This checklist covers the controls that matter most in 2025, from RBAC scoping to image provenance.
Kubernetes secrets management vulnerability guide
Kubernetes Secrets are base64, not encrypted. Real CVEs and the Tesla breach show how attackers exploit that gap — and how to close it.
Kubernetes Security Breaches: What Actually Happened in Real Incidents
Real Kubernetes security breaches rarely start with an exotic zero-day — exposed dashboards, misconfigured RBAC, and default credentials show up again and again.
Kubernetes 1.33 Security Deep Dive
Kubernetes 1.33 shipped with meaningful security changes: stronger admission controls, expanded structured authorization, and several deprecations that will affect production clusters.
What Is RBAC (Role-Based Access Control)
RBAC grants permissions to roles, then assigns people to roles. Learn how this model simplifies access management, its core parts, and where it fits best.
Kubernetes RBAC Security Best Practices for Supply Chain Protection
Misconfigured Kubernetes RBAC is a common path to supply chain compromise. Here's how to lock down permissions in your clusters.
