How to Set Up a Firewall for a Game Server
Game servers need specific ports open and everything else shut. Configure UFW to expose only your game's ports, protect RCON, and cut attack surface.

How to Scan a Linux Server for Malware (rkhunter, ClamAV)
Even hardened servers get probed. Learn to scan for rootkits and malware with rkhunter and ClamAV, read the results, and respond to a real detection.

How to Manage Secrets and Environment Variables on a VPS
Hardcoded API keys and passwords in code are a breach waiting to happen. Learn to store secrets in env files, systemd, and vaults — the right way.

How to Secure Docker Containers
Containers aren't secure by default. Run as non-root, drop capabilities, limit resources, scan images and lock down the daemon on your VPS.

How to Secure a Self-Hosted WordPress Site
WordPress powers a huge share of the web, which makes it a huge target. Harden your self-hosted install at the server, app, and login layers.

How to Secure a MySQL Database
An exposed or default-configured database is a breach waiting to happen. Lock down MySQL/MariaDB: bind to localhost, strong users, least privilege and TLS.

How to Set Up Automatic Security Updates on Ubuntu
Unpatched software is the top cause of server compromise. Configure unattended-upgrades so security patches install themselves — safely and unattended.

DDoS Protection Basics for a VPS
What a DDoS attack actually is, what you can mitigate at the server level, and where you genuinely need upstream protection. A realistic primer.

How to Protect a VPS from Brute-Force Attacks
Bots relentlessly guess logins against every public server. Here's a layered playbook — keys, firewall, rate limits and bans — to make brute-forcing pointless.

How to Add Two-Factor Authentication to SSH
Add a time-based one-time code on top of your SSH key for defence in depth. Set up Google Authenticator PAM without locking yourself out.

How to Disable Root Login on a VPS
The root account is every attacker's first guess. Learn to create a sudo user and disable direct root login over SSH — safely, without locking yourself out.

How to Set Up a UFW Firewall on Ubuntu
UFW makes Linux firewalling approachable. Learn to allow only the ports you need, set default-deny, rate-limit SSH, and verify your rules.
Deploy your first server in under a minute.
Creating an account is free and takes no card details. Every guide here runs on a Nxeon VPS or game server.
