It took 32 minutes from downloading the package to Nessus updating all its plugins before we were able to perform our first scan. We used our StationX email to complete the registration. It’s worth noting that a Gmail address was rejected as it had to be a “work” email. We needed to provide an email address to register an account and receive an activation key.

Once downloaded, we had to install it through the command line.Īfterward, we selected the Essentials version (which is the free version). We needed to go to the Tenable website and download the program. There were several steps to getting Nessus ready to go. Simply type “nmap” followed by the flags you wish to use in your scan, and your target. Since it is a command line tool, there is no bootup or login. Nmap comes pre-installed and configured in Kali Linux. In this section, we will set up each scanner to determine how easily and quickly we can have them up and running on our Kali Linux instance. GVM remains open-source but is not included by default on Kali Linux. GVM, much like the other scanners on this list, will perform a port scan on the target systems and check them for known vulnerabilities. GVM allows for authenticated and unauthenticated vulnerability scanning of individual targets or networks. While many still call it OpenVAS, we will use the new name, GVM.

The software began as a fork of Nessus after Nessus changed from open source to closed source. Until recently, OpenVAS used to be its own framework but is now part of the Greenbone Vulnerability Manager (GVM). OpenVAS (Open Vulnerability Assessment Scanner) was a vulnerability scanner managed by Greenbone Networks. This tool is not included by default on Kali Linux. It can scan individual targets or multiple targets in a network. Nessus offers a wide range of options to customize your scanning, including the intensity of the scan, the types of vulnerabilities to look for, and the ability to schedule a scan for a specific time and date. Tenable advertises Nessus as the number one tool for vulnerability assessment, scanning for over 75,000 CVEs (Common Vulnerabilities and Exposures).

Nessus is a vulnerability assessment tool made by Tenable, available as a free version, professional version, and expert version. There are outside repositories that can greatly increase the number of vulnerabilities Nmap can scan for, such as Vulners. Nmap has a powerful scripting engine that includes scanners for a wide range of known vulnerabilities. It comes preinstalled on Kali Linux and is often the first tool penetration testers use to enumerate their target. It has the ability to discover hosts on a network and provide a wealth of information on them, including the hostname, operating system, open ports, running services and service versions, and more.

Short for Network Mapper, Nmap is a free and open-source tool used for network discovery and security auditing.
