Apache Hide Server Token: Protecting Your Website from Hackers

Introduction

Greetings, fellow website owners! As you know, keeping your website safe and secure from hackers is crucial. One often overlooked aspect of website security is hiding the server token on your Apache web server. This simple step can go a long way in preventing malicious attacks. In this article, we’ll dive deep into what server tokens are and how to hide them on your Apache web server.

What is a Server Token?

When a browser connects to a website, the web server responds with a header that contains information about the server. This header is called the server token. It typically contains information such as the web server name, version number, and operating system.

Here’s an example of what a server token might look like:

Server	Version	Operating System
Apache	2.4.41	Ubuntu

While this information might seem harmless, it can be used by hackers to identify vulnerabilities in your web server. By hiding your server token, you can make it more difficult for attackers to gather information about your website and server.

How to Hide Server Tokens on Apache

Fortunately, hiding server tokens on an Apache web server is a simple process. Here are the steps:

Step 1: Edit Apache Configuration File

Open the Apache configuration file in a text editor. This file is typically located in the /etc/httpd/conf/httpd.conf directory.

Step 2: Locate the ServerTokens Directive

Search for the ServerTokens directive in the configuration file. This directive specifies what information is included in the server token. By default, the directive is set to Full, which includes all the information about the server.

Step 3: Change ServerTokens Directive

Change the ServerTokens directive to Prod. This will only include the essential information in the server token, such as the server name.

Step 4: Restart Apache

Restart the Apache web server for the changes to take effect. This can be done using the following command:

sudo systemctl restart httpd

The Advantages and Disadvantages of Hiding Server Tokens

While hiding server tokens can help improve website security, it also has its drawbacks. Let’s take a look at some of the advantages and disadvantages:

Advantages

1. Increased Security: Hiding server tokens can make it more difficult for attackers to gather information about your web server and website.
2. Compliance: Some regulatory requirements, such as PCI DSS, require hiding server tokens.
3. Better User Experience: Server tokens can take up unnecessary space in response headers, which can slow down website performance. Hiding server tokens can help improve website speed and user experience.

Disadvantages

1. Server Identification: Hiding server tokens can make it more difficult to identify what web server is being used, which can cause issues when troubleshooting or updating the server.
2. False Sense of Security: Hiding server tokens alone is not enough to protect your website from attacks. It should be used in conjunction with other security measures, such as firewalls and SSL.
3. Compatibility Issues: Hiding server tokens can cause compatibility issues with some web applications that rely on the server information in the header.

A: The ServerSignature directive is another Apache directive that controls whether the server version and operating system information is included in error messages generated by the server. This directive should also be set to Off for improved website security.

Q: Will hiding server tokens affect website performance?

A: Hiding server tokens can actually improve website performance by reducing the size of response headers.

Q: How can I test if my server token is hidden?

A: You can use a tool such as SecurityHeaders.com to check if your server token is hidden.

Q: Can hiding server tokens cause issues when updating Apache?

A: No, hiding server tokens should not cause any issues when updating Apache.

Q: Do other web servers have server tokens?

A: Yes, other web servers, such as Nginx and IIS, also have server tokens.

Q: Can I customize the server token?

A: Yes, you can customize the server token using the ServerTokens directive.

Q: Do all web hosts allow hiding server tokens?

A: It depends on the web host. Some web hosts may not allow users to modify their Apache configuration files, while others may provide tools to easily hide server tokens.

Q: Is hiding server tokens a requirement for GDPR compliance?

A: No, hiding server tokens is not a requirement for GDPR compliance.

Q: Can hiding server tokens prevent all attacks?

A: No, hiding server tokens should not affect SEO.

Q: What other security measures should I use in addition to hiding server tokens?

A: Other security measures to consider include implementing a firewall, using SSL, and regularly updating software and security patches.

Q: Is it difficult to hide server tokens?

A: Hiding server tokens is a simple process and can be done by editing the Apache configuration file.

Q: How often should I hide my server tokens?

A: Server tokens only need to be hidden once and should persist even after updating Apache.

Q: Can hiding server tokens be reversed?

A: Yes, hiding server tokens can be reversed by changing the ServerTokens directive back to Full.

Q: How long does it take for server token changes to take effect?

A: Server token changes should take effect immediately after restarting the Apache web server.

Conclusion

As website owners, it’s our responsibility to ensure the security of our websites and protect our users’ information. Hiding server tokens on our Apache web servers is a simple step we can take to improve website security. While there are some drawbacks to hiding server tokens, the benefits outweigh them.
