When you operate a Linux server, ensuring you are running a healthy, safe, and secure server should make it to the top of your primary list of objectives. There are many ways hackers and unscrupulous individuals can compromise servers, and you want to prevent an attack on yours.
Rootkits and How they Malign Your Servers
One of the most effective techniques hackers use to gain unauthorized access to your servers is through the installation of rootkits. Designed to hide malicious content, files, and processes within a server, a rookit provides attackers a way to connect to and utilize servers for conducting activities like phishing, enforcing botnet controller, and launching DDoS attacks.
How to Check Your Servers for Rootkits
Scanning your servers regularly for any potential rootkit installation will keep things going smoothly, and more importantly, safely. Fortunately, in today’s time and age wherein rootkits have affected so many servers, you will now find several scanners designed particularly to hunt these malicious processes down. One of them is The Rootkit Hunter project, more commonly referred to simply as rkhunter.

You can also run separate or bulk tests with the tool. Created originally by Michael Boelen back in the year 2006, a 3 person development team now manages this rootkit scanner.
The rkhunter Advantage
As mentioned above, there are several tools you can download to scan your machines and servers for rootkits. So why choose rkhunter? First and foremost, is because of its speed and ease of use. It provides you with a solution to keep your assets free of rootkit and other threatening, malicious programs.
