[GUIDE] 5 Critical Steps to protect your VPS from Hacks and Bans

🛡️ PROTECT YOUR INFRASTRUCTURE: A BEGINNER'S PROTOCOL

Hi everyone,
I see many beginners starting with their first VPS for nodes or wallets, but they often forget that a server is a magnet for hackers. With my professional background in Quality & Safety Audit (QHSE), I want to share a simple but powerful protocol to protect your digital assets.
In 2022, I learned that prevention is always cheaper than recovery. Here are the 5 Golden Rules you should apply right now:

1. 🚪 Change your SSH Port
Never leave it on port 22. Hackers use automated bots to scan this port 24/7. Use a random port (e.g., between 10000 and 60000). It stops 90% of basic attacks.
2. 🚫 Disable Root Login
Login as 'root' is a huge security risk. Create a new user with sudo privileges and disable root login in your sshd_config.
3. 🛡️ Install Fail2Ban
This tool is mandatory. It automatically bans any IP address that tries to guess your password more than 3 times. It's like having a digital security guard for your server.
4. 🔍 Check your IP Reputation
Before installing any wallet, check if your VPS IP is already Blacklisted (check Spamhaus or Barracuda). A "dirty" IP will get your exchange accounts banned instantly.
5. ⚙️ Regular Maintenance
Rigor is key. Run:

Code:

sudo apt update && sudo apt upgrade -y

at least once a week to patch security vulnerabilities.

Conclusion:
Security is not a product, it's a habit. If you are unsure about your current setup or if you think your IP might be flagged, feel free to ask.
