How Linux kernel live patching works in 2026 with kpatch, Ubuntu Livepatch, and TuxCare KernelCare. Install commands, comparison table, and audit tips for zero-downtime CVE fixes.
Wolfi vs Distroless vs Alpine base images for 2026 Linux workloads, with CVE benchmarks, apko and cosign pipeline snippets, and real migration examples for Node.js and Python services.
OpenBao 2.5 vs HashiCorp Vault in 2026: licensing under BUSL vs MPL 2.0, what's free in OpenBao, a real migration recipe from Vault CE 1.14.x, Kubernetes patterns with ESO, and a hardening checklist from a pentester's view.
Deploy Keylime continuous remote attestation on Linux with TPM 2.0: registrar, verifier, Rust agent, IMA runtime policies, and revocation webhooks in 2026.
Auto-unlock LUKS2 volumes at boot using Tang and Clevis NBDE. Covers install, sss threshold pins with TPM2, safe key rotation, and boot troubleshooting for headless Linux servers.
VEX is the layer between your SBOM and your scanner that says this CVE doesn't apply to us, and here's why. Walks through OpenVEX, CSAF VEX, vexctl, Trivy --vex, Grype match exclusions, and the CI pipeline pattern I run on every Linux build.
Kata Containers and gVisor both sandbox Linux containers but use very different mechanisms. This 2026 guide compares their isolation models, performance overhead, Kubernetes RuntimeClass setup, and when to pick each runtime for production workloads.
A practical walkthrough of Linux memory forensics with Volatility 3 in 2026: capturing RAM with AVML or LiME, building ISF symbol tables, running the plugin chain that catches LKM, LD_PRELOAD, and eBPF rootkits, and mapping each detection back to a hardening control.
Use BPF LSM (KRSI) to write dynamic kernel security policies in eBPF. Enable it on Linux 6.x, ship your first enforcement program, and stage audit-to-enforce rollouts safely.
Build, sign, and enroll Unified Kernel Images on Linux: ukify, sbctl, systemd-boot, and TPM2 PCR policies for a measured, tamper-evident Secure Boot chain in 2026.
Compare structured outputs and function calling across OpenAI, Anthropic, and Gemini in 2026. Includes Python code, vendor matrix, and eval metrics that catch the failures schema validation misses.
SPIFFE and SPIRE give Linux workloads short-lived, verifiable identities (SVIDs) for mTLS and JWT auth, replacing long-lived API keys and secrets.
