When you manage your own VPS, keeping it secure goes far beyond setting up a strong password or using SSH keys. One of the most important — and often overlooked — tasks is monitoring login attempts and file changes.
If someone tries to brute-force their way into your server or modifies system files without authorization, you need to know immediately. In this post, we’ll walk you through simple tools and methods to keep an eye on your VPS security 24/7.
For automation, schedule this via cron and configure it to email alerts.
🔁 Real-Time File Monitoring with
inotify-tools
For lightweight, real-time file monitoring (e.g., for specific web directories), use inotify-tools.
🔧 Install:
sudo apt install inotify-tools -y
Example: Watch for changes in
/var/www/html
:
inotifywait -m -r /var/www/html
This tool is great for developers and sysadmins wanting immediate feedback on file activity.
✉️ Optional: Email Alerts for Login & File Events
Combine these tools with email notifications or integrate them with your external monitoring system (Zabbix, Prometheus, or even a simple bash + mail setup) for real-time alerting.
🧠 Best Practices
🔐 Use SSH keys instead of passwords
🔒 Disable root login via SSH
🚫 Change default SSH port
📉 Monitor logs daily or automate alerting
🧾 Keep audit trails and backups

When managing your VPS or Virtual Dedicated Server (VDS), security should always come first. While many users rely on traditional passwords for remote access, SSH keys offer a far more secure and convenient alternative.
At Hosteons, we strongly recommend using SSH key authentication to secure your VPS access — and here’s why.
🔐 What Are SSH Keys?
SSH (Secure Shell) keys are a pair of cryptographic keys used to authenticate with a remote server:
Public Key: Stored on your VPS (e.g., in ~/.ssh/authorized_keys)
Private Key: Stored securely on your local device (e.g., ~/.ssh/id_rsa)
When you try to connect, your device proves ownership of the private key — no need to transmit a password.
🚫 The Problem with Passwords
Easily guessed or brute-forced
Often reused across multiple accounts
Susceptible to phishing or keylogging
Require manual entry each time
If your password is weak or exposed, your server is vulnerable.
✅ Benefits of Using SSH Keys
1.
Stronger Security
SSH keys are typically 2048-bit or 4096-bit, which are practically uncrackable by brute force.
2.
No Password Transmission
No password is sent over the network, making it immune to interception.
3.
Convenience
You can set up password-less login using your key, often combined with an SSH agent or passphrase.
4.
Script-Friendly
Automated deployments and Git-based workflows rely on SSH keys for secure, non-interactive authentication.
5.
Block Brute-Force Attacks
Once password authentication is disabled, bots and attackers can no longer guess credentials.
🛠️ How to Set Up SSH Key Authentication
Generate a Key Pair (on your local machine):
ssh-keygen -t rsa -b 4096
Upload the Public Key to Your VPS:
ssh-copy-id user@your-vps-ip
Or manually place the public key into ~/.ssh/authorized_keys
Disable Password Authentication:Edit /etc/ssh/sshd_config on your VPS:
PasswordAuthentication no
Then restart the SSH service:
systemctl restart sshd
🔒 Combine with Fail2Ban and Firewall
For maximum protection:
Use Fail2Ban to block repeated failed login attempts
Limit access to port 22 using UFW or CSF firewall
Change the default SSH port (optional)
🧠 Summary
Using SSH keys instead of passwords is one of the simplest yet most powerful steps you can take to secure your VPS or VDS.
Managing a new VPS can be overwhelming, especially when starting with a fresh Linux installation. That’s why we at Hosteons created a smart, interactive script to help new VPS users quickly set up their server with best practices in place—regardless of whether you’re using Ubuntu, Debian, AlmaLinux, CentOS, or Rocky Linux.
Here’s a complete WordPress blog post draft to promote your Fail2Ban Auto-Installer script from GitHub:
🔐 Automatically Install Fail2Ban with Smart Jail Detection on Your VPS (Script by Hosteons)
At Hosteons, we’re committed to making server security easier for everyone. Whether you’re running a small VPS or managing a fleet of Linux servers, protecting against brute-force attacks is critical.
That’s why we’ve created a Fail2Ban Auto-Installer Script that not only installs Fail2Ban but also auto-detects and enables jails for common services like SSH, Apache, and Nginx — all in one click.
This script runs perfectly on our KVM VPS and Ryzen VPS plans. Visit hosteons.com to explore secure hosting powered by NVMe SSD and DDoS protection — with native support for IPv6, WireGuard VPN, and more.
Secure Your Linux VPS in One Click with Our Rootkit & Malware Scanner
Running a VPS or dedicated server? One of the most overlooked but critical steps is making sure your system is free of rootkits and malware.
To simplify this task, we at Hosteons have released a free and open-source script that automatically installs, updates, and runs malware and rootkit scans using two of the most trusted tools in the Linux ecosystem:
ClamAV – an open-source antivirus engine
RKHunter – a rootkit scanner that checks for backdoors, local exploits, and suspicious files
🔧 What the Script Does
Detects your Linux distribution (Ubuntu, Debian, CentOS, AlmaLinux)
Installs ClamAV and RKHunter
Automatically updates malware and rootkit signature databases
Fixes common errors like WEB_CMD=”/bin/false” in RKHunter config
Runs full ClamAV scan
Executes a complete RKHunter rootkit check
Compatible with minimal or fresh VPS installations
📥 Download and Run
Run the following commands to download and execute:
All actions run with user confirmation and are fully transparent
⚠️ Note
This script is non-destructive – it only scans and reports. It does not automatically delete or quarantine any files. Always review flagged files before taking any action.
🎯 Why Use This?
Ideal for hosting providers and system admins
Perfect for VPS users looking for a quick, effective scan
Good first step after initial OS setup
🙌 Contribute or Report Issues
You can fork, improve, or report bugs directly on GitHub:
Managing a Windows VPS often requires securing RDP (Remote Desktop Protocol) access. One of the most effective and simplest ways to harden your Windows Server is to change the default RDP port (3389). But doing it manually via the registry and firewall can be tedious and risky.
That’s why we at Hosteons created an open-source, one-click PowerShell script that simplifies the process.
⚠️ Important: Make sure your port is not blocked by external firewalls (such as cloud provider rules). Also, ensure you have console/VNC access in case the new port is misconfigured.
🤖 Automation Friendly
This script can be integrated into automation flows for server provisioning or batch management. Perfect for sysadmins managing multiple Windows VPS instances.
🔐 Why Change Your RDP Port?
Reduces brute-force attacks from bots scanning port 3389
Hides your RDP service from default port scanners
Adds an extra layer of obscurity in your defense

Hosteons is a VPS and dedicated server provider offering services in multiple global locations. We’re committed to open-source and providing useful automation tools for system administrators and developers.
Managing a Linux server? Whether you’re running Ubuntu, Debian, CentOS, or AlmaLinux — one of the first steps after setup should be hardening your system against attacks.
At Hosteons, we’ve created a powerful yet easy-to-use Linux Hardening Script that automates the most essential security tasks. Best of all — it’s completely open-source under the MIT License.
🔧 What Does the Script Do?
Our script walks you through an interactive setup process that includes:
✅ Changing the default SSH port
✅ Disabling root SSH login (optional)
✅ Creating a new sudo-enabled user (if root login is disabled)
✅ Installing and configuring Fail2Ban to block brute-force attacks
✅ Installing and initiating a Lynis audit for best practices
✅ Enabling and configuring UFW (Ubuntu/Debian) or Firewalld (CentOS/AlmaLinux)
✅ Handling SELinux if enabled
✅ Updating all system packages
All steps are automated and clearly explained during the process.
🚀 Why Harden Your Server?
Running a public-facing server without basic security is like leaving your front door open. Common exploits target:
Default SSH ports
Password-authenticated root logins
Unpatched packages
Open ports and misconfigured firewalls
This script helps new VPS users and sysadmins apply battle-tested security practices without manual work.
Follow the prompts — it’s fully interactive and safe
💡 Disclaimer: Changing SSH ports and disabling root login may lock you out if you’re not careful. Always have VNC, IPMI, or another form of console access ready.
