audit logging

Practical, Bash-first guide to hardening Model Context Protocol servers on Linux: treat MCP as a new security perimeter against prompt injection, exfiltration, and lateral movement using least‑privilege systemd sandboxes, bubblewrap/Podman, Unix sockets + tight firewalls, TLS/nginx or SSH/WireGuard, strict secrets handling, auditd + allowlists/fail2ban, and step‑by‑step configs—plus a real-world case and 4-step checklist.

Practical guide to securely installing and hardening Ollama on Linux: keep the API bound to localhost and blocked by firewalls; if exposing, use a reverse proxy with TLS, auth, CORS limits and rate limiting; verify and pin model digests with locked-down permissions; avoid secrets in prompts and logs; update, monitor and back up routinely; and optionally isolate with a rootless container for extra defense.
