Nessus is a remote security scanning tool that scans your computer. It should also be noted that Nessus warns of any vulnerabilities that malicious hackers can use to gain access to any computer you connect to the network. It does this by running more than 1,200 checks on a specific computer and testing whether any of these attacks can be used to infiltrate or damage a computer. In this article, we are going to teach you How to Install and Configure Nessus On Debian 11. You can see the packages available in Eldernode if you want to buy a Linux VPS server.

Introduction to Nessus and its Features

You may be wondering what benefits Nessus has over them. Unlike other scanners, Nessus does not presuppose the configuration of your server (assuming port 80 should be the only webserver), which can cause other scanners to lose real vulnerabilities.

It should also be noted that Nessus is highly extensible and provides you with a scripting language so that you can write your own system tests after becoming more familiar with the tool. Nessus has a plugin interface and many free plugins are available from the Nessus plugin site.

The Nessus team updates the list of vulnerabilities that should monitor daily to minimize the distance between an exploit that occurs in nature. So you will be able to recognize it with Nessus.
