In 1998 Renaud Deraison created The Nessus Project as a free remote security scanner.[2] On October 5 2005, with the release of Nessus 3, the project changed from the GNU Public License to a proprietary license.[3]
Nessus is one of the many vulnerability scanners used during vulnerability assessments and penetration testing engagements, including malicious attacks. This article will focus on this vulnerability scanner, discussing the fundamentals that one needs to have before getting started with the tool, the different scanning capabilities that it provides, what it takes to run the tool and how results appear once scans are complete.
The Nessus user interface is primarily made up of two main pages: the scans page and the settings page. These pages allow you to manage scan configurations and set up the scanner according to how you would like it to perform within your system. You access these pages from the tab panel shown below.
This page will allow you to create your new scans and manage them. You will also note that at the bottom left section of your screen, you have sections that allow you to configure policies that will apply to your scans, define plugin rules and monitor your scanners and agents as well. When you create a new scan or policy, a Scan Template or Policy Template appears.
Assessment: This setting allows you to determine the type of vulnerability scan to perform and how they are performed. Nessus will check the susceptibility of Web applications to attacks and other systems to brute-force attacks as well. This setting has sections that allow you to customize general scans to Windows, SCADA, Web applications, and even brute-force checks.
Nessus can be installed on a virtual machine that meets the same requirements. If your virtual machine is using Network Address Translation (NAT) to reach the network, many of the Nessus vulnerability checks, host enumeration, and operating system identification are negatively affected.
Tenable Network Security specializes in continuous monitoring and vulnerability assessment products. Tenable's Nessus vulnerability scanner product line includes Nessus Cloud, which is a software as a service offering; Nessus Manager, an on-premises physical or virtual appliance for vulnerability management; Nessus Professional, which is software that runs on a client device such as a laptop; and Nessus Home is a free version that's aimed at consumers.
The Tenable Nessus product line is one of the most comprehensive in the vulnerability management space and has been an established presence in the market for years. In addition to vulnerability scanning of the infrastructure with automatic scan analysis for remediation prioritization, Nessus includes web application, cloud environment and mobile device scanning. The Nessus vulnerability scanner family also provides malware detection, auditing of control systems such as SCADA and embedded devices, and configuration auditing and compliance checks.
The Nessus scanning engine uses plug-ins to detect new vulnerabilities. Tenable pushes plug-ins that contain the latest information to customer systems within 24 hours after a vulnerability has gone public. Because new vulnerabilities appear nearly every day, customers receive daily plug-in feeds to stay current.
Nessus Cloud and Nessus Manager easily integrate with CyberArk for credential management, with patch management systems such as those from Dell, IBM, Microsoft and Red Hat, and with mobile device management systems like those from AirWatch, MobileIron, Apple, Microsoft and others. All Nessus vulnerability scanner products work with the RESTful API to integrate Nessus into an organization's overall workflow.
In addition to the Nessus vulnerability scanner line, Tenable also offers SecurityCenter, a unified network monitoring and vulnerability management analytics control center, and SecurityCenter Continuous View, a monitoring product with real-time threat detection.
The Nessus vulnerability scanner products are annual subscription-based products sold through a sales partner or directly through the online Tenable Store. Nessus Cloud and Nessus Manager subscriptions are priced the same per number of hosts or agents; 128 hosts or agents costs $2,920, for example, while 256 hosts or agents costs $4,745. Customers with more than 256 hosts must contact a sales representative for specific pricing. Each subscription includes one year of software updates and vulnerability updates.
