+# Gitea Hardening Notes
+
+## Minimum Hardening
+- Put Gitea behind reverse proxy (nginx/Traefik) with TLS
+- Disable public registration if not needed
+- Enforce 2FA for admin/org owners
+- Restrict SSH to known networks or require VPN/tunnel
+- Back up the data dir regularly (repos + config + sqlite/db)
+
+## Backups
+If using sqlite, backing up `/data/gitea/gitea.db` plus repos is enough.
+For Postgres/MySQL, dump database + repos.
+
+## Next Skills
+- container-registry (self-hosted with signatures)
+- dns-sovereign (PowerDNS + Cloudflare hybrid)
