Your server contains your website, emails, and critical business information. If not secure, hackers can hack your data, slow down your site, or take it offline. Any business, whether small or large, should take server security seriously.

You don’t need to handle everything on your own — securing a server requires the right technical support. A professional team can manage server updates, monitor performance, and protect against security threats, so you can focus on running your business without worrying about technical issues. Services like ServerManagement.lk offer expert server management and 24/7 monitoring to keep your data safe and your business online.

Simple Guidelines to Secure Your Server

1. Keep Your Software Updated

Always have your server's operating system, control panel (cPanel or Plesk, for example), and site software (WordPress, Drupal, Joomla, etc.) updated to the current version.

Security patches fix security problems. Spammers target older or outdated software servers. Keeping everything current drastically lowers the spammers' and crackers' chances of getting in.

2. Use a Firewall

A firewall blocks unwanted traffic and helps protect your server from intrusions.

You need to use both a network-level firewall (like iptables) and an application-level firewall (like ModSecurity). A firewall gives an added layer of protection and keeps hackers from accessing your server.

3. Secure Remote Access (SSH)

If a hacker remotely accesses your server, he can try to hack it. To make it secure:

  • Use public key authentication instead of passwords.

  • Disable root login.

  • Use tools like Fail2ban to block repeated login attempts.

This makes it much harder for hackers to access your server.

4. Use Strong Passwords and Two-Factor Authentication

Always use strong, unique passwords for all accounts on your server. Avoid easy or repeated passwords.

Enable two-factor authentication (2FA) wherever possible, especially for admin accounts. 2FA makes it much harder for hackers to log in, even if they know your password.

5. BackUp Your Data Periodically

Periodically backup your server data. Test backups to make sure you can restore them in a timely way as needed.

Backup data in a secure offsite location and encrypt it so that your data is safe. Periodic backups protect your website and business in the event something goes wrong.

6. Restrict User Access

Grant users only the access they need. Don't give admin access to general users.

Limit user access to reduce risk in the event that an account is hacked. Each user must only be able to view the files and operations they need in order to perform their work.

7. Protect Your Website from Attacks

Your website can be hacked using methods like SQL injection or cross-site scripting (XSS). To protect your website:

  • Implement input validation to validate user input.

  • Use prepared statements when querying a database.

  • Use a Web Application Firewall (WAF).

These actions keep information thieves from stealing data or crashing your site.

8. Monitor Your Server

Review server logs consistently for abnormal activity.

Create alerts for such as:

  • High CPU usage

  • Repeated failed attempts at login

  • Unrecognized processes running

Monitoring keeps you from catching problems late, when hackers can cause huge amounts of harm.

9. Use Encryption

Utilize SSL/TLS (HTTPS) for your website to encrypt data received and sent by users.

Encrypt sensitive data on your server. Encryption secures your data, even if someone tries to read it without permission.

10. Security Scans

Scan your server for vulnerabilities to determine weak points. Hire experts to conduct penetration tests.

The scans allow you to fix problems before hackers find them. Security testing on a regular basis keeps your server secure and immune.
