chkrootkit Linode Ubuntu | An Introduction

With cybersecurity being of utmost importance, we need to have proactive measures to protect our digital assets.

One such tool is the chkrootkit tool. We can deploy it on our virtual server hosted on Linode and run the Ubuntu Linux distribution.

At its core, chkrootkit is a powerful security tool. It is designed to root out rootkits that can grant unauthorized access to our server and compromise its integrity. In other words, with this tool, we can boost our server’s defenses.

How to install and deploy chkrootkit

1. First, we have to start a secure connection to our Linode server via SSH.
2. Then, we must update our package lists with this command:

   sudo apt update
3. Now, it is time to install chkrootkit as seen here:

   sudo apt install chkrootkit
4. After that, we have to start a scan with chkrootkit to identify potential rootkit threats.
   We have to run this command for seamless access to system files:

   sudo chkrootkit

   This command runs a complete scan of our system and looks for known rootkit signatures and suspicious files. The outcomes of this scan will be displayed on the terminal.
5. This step is optional. We can automate the scanning process by creating a cron job that schedules chkrootkit to run at fixed intervals.
6. Finally, we have to save the changes and exit the editor.
