How to Safeguard Apache Web Server on Ubuntu

Apache is the cornerstone of modern web servers and is a powerful software solution for a large percentage of today's internet economy.

According to a July 2018 research published by w3techs, Apache has a market share of around 45.9%. That being said, Apache web server is targeted by most hackers. The software is secure out-of-the-box but you can still harden it with some additional modules.

One of the most common methods of securing your Apache web server hosted on Alibaba Cloud is installing ModEvasive. This is a highly intelligent Apache module that provides evasive actions against Distributed Denial of Service and Brute Force attacks.

In this guide, we will show you how to safeguard your Apache web server hosted on Alibaba Cloud Elastic Compute Service (ECS) against DDoS and brute-force attacks.

Setup Apache Web Server

The next step is installing Apache web server. You can skip this command if you have already installed the software on your system.

$ sudo apt-get install apache2

Press Y and hit Enter when prompted to confirm the installation.

You can always check if Apache is working by entering your server's public IP address on a web browser.
