Brute-Force Attacks Explained and How to Prevent Them

Leave a Comment on Brute-Force Attacks Explained and How to Prevent Them

One of the most common threats faced by servers and websites today is the brute-force attack. Whether you’re hosting a blog, an e-commerce store, or applications on a VPS, understanding brute-force attacks is essential for keeping your data and users safe.

At Hosteons, we take server security seriously and encourage all customers to harden their VPS right after deployment. Here’s everything you need to know about brute-force attacks — and how to prevent them.

🔎 What Is a Brute-Force Attack?

A brute-force attack is when hackers try to guess login credentials by repeatedly attempting different combinations of usernames and passwords. They use automated tools that can test thousands (even millions) of combinations in minutes.

The goal is simple: gain unauthorized access to your VPS, control panel, CMS (like WordPress), or email accounts.

⚠️ Why Brute-Force Attacks Are Dangerous

  • Unauthorized Access – Hackers can gain root or admin access.
  • Data Theft – Sensitive customer or business data may be stolen.
  • Malware Installation – Attackers may install ransomware or backdoors.
  • Resource Overload – Constant login attempts can overload your server.

🛡 How to Prevent Brute-Force Attacks

1. Use Strong, Unique Passwords

Avoid simple or repeated passwords. Use a password manager to generate and store complex credentials.

2. Enable SSH Key Authentication

For VPS access, disable password logins and use SSH keys instead. This makes brute-force attempts nearly impossible.

3. Change Default Ports

Move services like SSH (default port 22) or RDP (default port 3389) to non-standard ports to reduce automated attack attempts.

4. Install Fail2Ban or CSF

These tools monitor login attempts and automatically ban IPs showing suspicious activity.

5. Limit Login Attempts

Configure your CMS or control panel to lock accounts after too many failed attempts.

6. Enable Two-Factor Authentication (2FA)

Adding an extra verification step ensures attackers can’t get in even if they guess the password.

7. Monitor Logs Regularly

Check your server logs to detect unusual login attempts early.

8. Keep Software Updated

Outdated software often has vulnerabilities that brute-force bots exploit.

🚀 How Hosteons Helps Keep You Secure

When you choose Hosteons VPS or VDS hosting, you get:

  • Full root access to configure strong security
  • Ability to install Fail2Ban, CSF, or WAFs
  • Support for 10Gbps ports to handle high traffic securely

  • Global server locations with reliable infrastructure

✅ Conclusion

Brute-force attacks are one of the oldest tricks in the hacker’s playbook, but they remain a serious threat. The good news? With a few proactive steps like using SSH keys, enabling firewalls, and monitoring logs, you can effectively protect your VPS and websites.

At Hosteons, we provide the tools and flexibility to secure your hosting environment from day one.

How to Protect Your VPS from Hackers in 2025

Leave a Comment on How to Protect Your VPS from Hackers in 2025

A Virtual Private Server (VPS) gives you power, control, and flexibility for hosting your websites, apps, or projects. But with great control comes great responsibility — and in 2025, cyberattacks are more sophisticated than ever. To keep your VPS safe, you need to apply strong security measures right after deployment and maintain them regularly.

At Hosteons, we encourage all VPS users to take security seriously. Here’s how to protect your VPS from hackers in 2025.

🔑 1. Use Strong Authentication

  • Change the default SSH port from 22 to something less predictable.
  • Disable password-based logins and switch to SSH key authentication.
  • Use strong, unique passwords for all accounts if passwords are unavoidable.

🔒 2. Keep Software Updated

Hackers often exploit outdated software. Run regular updates on your VPS:

apt update && apt upgrade -y   # Ubuntu/Debian  
yum update -y                  # CentOS/AlmaLinux

Enable automatic security updates where possible.

🛡 3. Configure a Firewall

Set up firewalls like UFW (Uncomplicated Firewall) or CSF to allow only necessary traffic and block everything else. Combine it with Fail2Ban to automatically block suspicious IPs.

🚨 4. Monitor and Audit Logs

Use tools like Logwatch, GoAccess, or external monitoring systems to watch login attempts, unusual traffic, and system resource spikes. Early detection helps prevent breaches.

👤 5. Limit Root Access

  • Create a separate user with sudo privileges.
  • Disable direct root login via SSH.
  • Use role-based access if multiple people manage the server.

🔐 6. Secure Applications and Databases

  • Keep web apps, CMS platforms (like WordPress), and plugins up to date.
  • Restrict database access to localhost unless remote access is absolutely required.
  • Use strong credentials for MySQL/MariaDB and any control panels.

📦 7. Enable Regular Backups

Even with the best defenses, no system is 100% secure. Automated backups ensure you can recover quickly in case of a hack, data corruption, or accidental deletion.

🌐 8. Consider a WAF or DDoS Protection

Adding a Web Application Firewall (WAF) or enabling DDoS mitigation can stop malicious traffic before it reaches your VPS. Cloudflare and other providers offer affordable protection options.

Top Security Steps You Should Take After Buying a VPS

Leave a Comment on Top Security Steps You Should Take After Buying a VPS

A Virtual Private Server (VPS) gives you power, flexibility, and control over your hosting environment. But with that control comes responsibility — especially when it comes to security. Right after you deploy a VPS, there are essential steps you should take to protect it from hackers, malware, and unauthorized access.

At Hosteons, we want our customers to stay secure from day one. Here’s a checklist of the top security steps you should take after purchasing a VPS.

🔑 1. Change the Default SSH Port

Most VPS servers use port 22 for SSH access by default, which makes it an easy target for brute-force attacks. Change it to a non-standard port for better protection.

🔒 2. Set Up SSH Keys Instead of Passwords

Using passwords alone is risky. Instead, configure SSH key authentication. This ensures only devices with the correct private key can access your VPS.

🛡 3. Configure a Firewall

Install and configure a firewall like UFW (Uncomplicated Firewall) or CSF (ConfigServer Security & Firewall) to block unauthorized traffic and allow only the services you need.

🚨 4. Install Fail2Ban

Fail2Ban helps prevent brute-force attacks by banning IPs that show malicious behavior, such as repeated failed login attempts.

📦 5. Keep Your System Updated

Always run system updates regularly:

apt update && apt upgrade -y   # Ubuntu/Debian  
yum update -y                  # CentOS/AlmaLinux

This ensures you have the latest security patches.

👤 6. Create a Non-Root User

Running everything as root is risky. Create a regular user account with sudo privileges to reduce exposure if compromised.

🔐 7. Secure Critical Services

  • Disable unused services to reduce entry points.
  • Restrict database access to localhost unless remote access is absolutely necessary.
  • Use strong, unique passwords for all accounts.
