Did you know your VPS receives unauthorized access attempts from the first minute you turn it on? 😅
The first time I deployed my own server, I ran this:
grep "Failed password" /var/log/auth.log
Hundreds of login attempts — bots scanning port 22 nonstop 🔥. That's when I understood that an exposed, unconfigured server is an open door.
These are the configurations I always apply:
🔒 𝗗𝗶𝘀𝗮𝗯𝗹𝗲 𝗿𝗼𝗼𝘁 𝘃𝗶𝗮 𝗦𝗦𝗛 — never let root in directly.
🔑 𝗦𝗦𝗛 𝗸𝗲𝘆 𝗮𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰𝗮𝘁𝗶𝗼𝗻 — eliminate password-based access.
🛡️ 𝗨𝗙𝗪 𝗲𝗻𝗮𝗯𝗹𝗲𝗱 — only open the ports you actually need.
🚫 𝗙𝗮𝗶𝗹𝟮𝗯𝗮𝗻 𝗿𝘂𝗻𝗻𝗶𝗻𝗴 — bans IPs that fail login multiple times.
🔄 𝗦𝘆𝘀𝘁𝗲𝗺 𝘂𝗽𝗱𝗮𝘁𝗲𝗱 — updates close real vulnerabilities.
It's not glamorous. It's not what they teach you first. But it's what separates a server that lasts from one that ends up mining cryptocurrency 💻.
If you have a VPS, run that command right now and tell me what you see 👇
