Container and Kubernetes scanning in agent-driven DevOps, without new trust boundaries
Autonomous agents that rebuild and redeploy containers can patch a CVE in under an hour — or become a new privileged path to production if scanning isn't gated.
Writing a Container Security Policy That Actually Holds
Most container security policies get written once, ignored during the next sprint, and rediscovered during an audit — here's how to write one that engineers actually follow.
Container Runtime Security Monitoring: Catching the Breach in Progress
Scanning tells you what could go wrong before deploy. Runtime monitoring tells you what is going wrong right now. Here is how to detect container attacks as they happen.
Defense-in-depth for a modern cloud-native application stack
Log4Shell and the XZ backdoor were caught two different ways — one by patching, one by a developer noticing 500ms of extra SSH latency. Neither alone is a strategy.
The GitOps security model: risks and controls
GitOps turns a Git repo into a deploy button — Argo CD's own CVE-2022-24348 path traversal proved what happens when that button isn't locked down.
Implementing mTLS in Kubernetes clusters: a hands-on guide
Kubernetes ships zero built-in encryption for pod-to-pod traffic — here's how cert-manager and service meshes fix that, and the five misconfigurations that quietly undo it.
Rego for security engineers: a beginner's guide to OPA policy
Rego graduated from Styra research project to a CNCF-graduated standard in under five years. Here's how to write your first real OPA/Conftest policy.
Hardening Amazon EKS With Native AWS Controls
AWS secures the EKS control plane and etcd — everything else, from IAM to security groups to node OS patching, is on you under the shared responsibility model.
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.
Container runtime security (containerd/CRI-O) vulnerability roundup
Container runtime CVEs like the runc Leaky Vessels flaw and CRI-O's cr8escape show how containerd and CRI-O bugs turn into full host takeovers.
Securing Managed Kubernetes: EKS, AKS, and GKE Compared
A cross-cloud guide to hardening managed Kubernetes — the shared responsibility line, cloud IAM-to-pod integration, network policy, Pod Security Standards, and node hardening across EKS, AKS, and GKE.
Containers Not Dropping Default Linux Capabilities
Docker grants every container 14 Linux capabilities by default. Here's why NET_RAW, SYS_CHROOT, and friends turn contained compromises into breakouts—and how to drop them safely.
