Nessus vulnerability scanner includes scan capabilities for network devices (Juniper, Cisco, firewalls and printers), virtual hosts (Vmware), operating systems (Windows, Mac, Linux, Solaris, BSD, Cisco iOS, and IBM iSeries), databases (Oracle, MS-SQL, MySQL, DB2, Informix/DRDA, PostgreSQL), and web applications (Web servers, web services and OWASP vulnerabilities). Credentialed scans are scans in which the scanning computer has an account on the computer being scanned that allows the scanner to do a more thorough check. Nessus enables businesses to detect threats within networks during updates, after the addition of new assets, and across hybrid or integrated ecosystems. It is a remote security scanning tool which scans a system and raises alert when it discovers any vulnerabilities which malicious hackers can use to gain access to any system connected to networks. Over the last 15 years it had evolved from only vulnerability scanner to include assessment and auditing features such as auditing of configurations, compliance auditing, patch auditing, control systems auditing, and mobile devices auditing. It is one of the most widely used vulnerability assessment products. In October 2005 Tenable network security changed Nessus 3 to a proprietary (closed source) license. Nessus was founded by Renuad Deraison in 1998 to provide the network community a free remote security scanner. Nessus: The Network Vulnerability Scanner We will explore more about its features, architecture, and use cases. Today we look at ‘ Nessus ’ Vulnerability scanner which is a very popular and widely used vulnerability scanner by small, medium, and large enterprises. There are many vulnerability management scanners / tools available in the market which help to identify and fix potential vulnerabilities, identify inventory / asset, automated patching to fix vulnerabilities etc. Vulnerability management is all about identifying, evaluating, treating, and reporting security vulnerabilities in systems and software and it is vital for organizations to prioritize potential threats and reduce the ‘attack surface’. ![]()
