Introduction
Greetings to all the tech enthusiasts! Today, we will be discussing a crucial topic that web developers encounter while creating and deploying cloud servers. When you develop a web application, you may want to hide the server’s name from visitors and clients for security reasons. However, Apache, a popular web server software, displays the server’s header information by default. This information can be a vulnerability for your cloud server as it gives away your server’s information to attackers. In this article, we will talk about how you can remove the DigitalOcean Apache Server header and its benefits and drawbacks.
What is DigitalOcean Apache Server Header?
Before understanding how to remove the DigitalOcean Apache Server header, let us first discuss what it is. When a user requests a web page from a server, the server sends a response containing various HTTP headers. These headers provide information about the server, the content type, the cookies, and more. One of these headers is the Server header, which displays the server’s name and version number. DigitalOcean uses Apache as its default web server software, which displays the server header by default.
Why Remove DigitalOcean Apache Server Header?
The server header information may seem harmless, but it can be a potential security vulnerability. If an attacker knows the server and its version number, they can target specific weaknesses or vulnerabilities in that server. This vulnerability can lead to data breaches, server downtime, or even complete server takeover. Keeping the server header hidden can help protect your server against such attacks.
How to Remove DigitalOcean Apache Server Header?
Now let’s dive into the process of removing the DigitalOcean Apache Server header. There are two ways to accomplish this task: using a web server module or modifying the Apache configuration file.
Method 1: Using a Web Server Module
You can use the mod_headers module in Apache to modify the headers sent in the HTTP response. Here are the steps:
Step |
Action |
|---|---|
Step 1 |
Login to your DigitalOcean droplet using SSH. |
Step 2 |
Type the following command to install the mod_headers module: sudo apt-get install libapache2-mod-headers. |
Step 3 |
Edit the Apache configuration file by typing sudo nano /etc/apache2/apache2.conf. |
Step 4 |
Add the following lines to the configuration file: Header unset Server |
Step 5 |
Save and close the file by typing Ctrl+X, then Y, and then Enter. |
Step 6 |
Restart the Apache server by typing sudo systemctl restart apache2. |
Method 2: Modifying the Apache Configuration File
You can also modify the Apache configuration file directly to remove the server header. Follow these steps:
Step |
Action |
|---|---|
Step 1 |
Login to your DigitalOcean droplet using SSH. |
Step 2 |
Type the following command to open the Apache configuration file: sudo nano /etc/apache2/conf-enabled/security.conf. |
Step 3 |
Under the <Directory /> section, add the following lines: ServerTokens Prod |
Step 4 |
Save and close the file by typing Ctrl+X, then Y, and then Enter. |
Step 5 |
Restart the Apache server by typing sudo systemctl restart apache2. |
