Set up fail2ban for SSH and Nginx with AbuseIPDB reporting, incremental bans, and daily blacklist imports from AbuseIPDB, Bitwire, and Spamhaus — a layered defense that catches bots before they reach your application.

A practical guide to locking down SSH access: Ed25519 keys, sshd_config hardening, fail2ban, port changing, and key management for single-admin servers.

Basic authentication in Nginx is a quick way to gate a directory, an admin area, or an entire staging site behind a username and password. It's not a replacement for a full login system, but for internal tools, dev environments, or adding a second layer in front of something already protected, it does the job with almost no overhead.
