The major difference between the two is that you can only scan up to 16 IP addresses per scanner, and you won’t be able to perform compliance checks and content audits with Nessus Home. It has two versions: Nessus Home and Nessus Professional. Nessus is a vulnerability scanner developed by Tenable. In this blog, I will guide you through the process of performing a VA against your network using Tenable Nessus. However, average home users should also conduct vulnerability assessment against their network. It is recommended that you conduct a VA against your organization’s network every quarter, and if your organization follows certain policy and standards, such as PCI DSS or ISO 27001, VA is a mandate. The results of the scan will show how an application, website or other system is vulnerable, but it doesn’t provide details on what would happen if the vulnerability was exploited. Imagine a burglar looking for and identifying different entrances to your building, but not entering. VA is a process of identifying security vulnerabilities in a system. If you work in the field of Infosec, you have probably heard of Vulnerability Assessment (VA).

NESSUS BASIC NETWORK SCAN INSTALL

For this scan there’s nothing incredibly interesting as the machine I scanned is a basic CentOS install with no open services, so I didn’t expect to find anything. Once the scan completes you can review the results.Īs you can see, Nessus identified 14 potential vulnerabilities that can be investigated further. For that, you’ll need to configure Nessus further, possibly even installing agents on the host that can probe deeper into the system. The basic network scan will only scan the host from the outside and can’t determine an extensive amount of details. Please note though that this basic scan is not going to be a thorough list of all vulnerabilities on the host. Nessus will then kickstart a basic network scan to identify vulnerabilities on the host.

Type the IP address of the potentially vulnerable host you wish to scan and click ‘Submit’ followed by ‘Run Scan’. Once setup has completed you’ll be presented with the dashboard and a prompt to create your first scan.įor the purposes of this demo, I’ve got another virtual machine running CentOS Linux that I’ll scan. Nessus needs to download and install plugins and initialise the installation before it can be used, this can take a while depending on the resources available on your machine. Once you’ve activated Nessus you’ll have to wait for a few minutes for setup to complete. I just filled in the form and pasted the key into the next page.

Note: There are a number of ways to install a package in Linux. Next open a terminal window and install the package. As I’m using Kali Linux, I’ll download the latest Debian amd64 version.

Using Nessus you can scan hosts across your network and generate reports on the vulnerabilities discovered so that they can be remediated before an incident occurs.įirst thing’s first, head over to the Nessus downloads page and download the package appropriate for the machine you’ll be using. Having knowledge of the vulnerabilities present in your environment is critical in defending against Cyber attack. In this article I’ll describe setting up Nessus in Linux to scan remote hosts.

I’ve also had the opportunity to deploy Nessus agents across a fleet of hundreds of Linux servers and run extensive scans from Tenable cloud.
