I will harden and configure your linux server for production use
About this Gig
Is your Linux server sitting exposed with default settings? I'll configure it the right way. What I do: - Initial server hardening: disable root SSH login, key-based auth only, change default SSH port - UFW firewall configuration (allow only what your app needs) - Create non-root sudo user for operations - Automatic security updates setup - fail2ban for brute-force protection - System audit and recommendations report I've hardened my own production home server running 6+ services continuously. I know what matters and what's just checkbox compliance. All work is documented. You get a written handover report of every change made and why.

FAQ
What do you need to get started?
Your server's SSH credentials (IP, port, username, and private key or password), the OS version, and a list of any services currently running. I'll handle the rest.
Will hardening break my existing services?
No. I audit what's running before touching anything. UFW rules are configured to keep your existing services accessible. I test connectivity after every change before closing the session.
What Linux distributions do you support?
Ubuntu 20.04 / 22.04 / 24.04 and Debian. These cover 90% of VPS deployments. If you're on CentOS or another distro, message me first.
Do you need root access?
Preferably yes for the initial setup. If you only have a sudo user, that works too — just let me know in the order requirements.
What do I get at the end?
A written summary of every change made, what it does, and how to maintain it. Not just a "done" message — a document you can reference later.
What if something stops working after delivery?
I offer free fixes for 3 days after delivery if something breaks as a direct result of my changes. Outside that window, message me and we'll work something out.
Can you harden a server that already has apps running on it?
Yes, and that's the more common scenario. I'll audit the existing setup first and won't touch anything that would disrupt running services without telling you.
