Learn how to securely verify Elasticsearch snapshots without using manage_snapshot, using a minimal API key, Prometheus-compatible script, and hardened monitoring practices. Includes a GitHub tools repo for automation.

Hardening Kubernetes workloads goes beyond RBAC tweaks or image scans. This post shares field-tested pod-level guardrails—like non-root containers, dropped Linux capabilities, and read-only filesystems—aligned with the Pod Security Standards (Restricted profile).

In memory-constrained environments, the Linux OOM Killer decides what lives and what gets killed. This guide shows how to protect critical processes like sshd and mysqld using oom_score_adj values, with a script that applies them reliably and securely. Make memory pressure predictable and survivable.

In 2012, I uncovered a state-aligned Twitter proxy tied to Venezuela’s ruling party. It mimicked Twitter, redirected traffic, and risked phishing user credentials.
