Tenable Network Security is currently seeking talented individuals to fill several roles within the company. Tenable Network Security is a privately held company founded in 2002 by security product innovators Ron Gula, Renaud Deraison and Jack Huffard. Together with Tenable CSO Marcus Ranum, they have developed a Unified Security Monitoring approach based on the award-winning Nessus scanner engine leveraged with several other enterprise vulnerability and log management products such as SecurityCenter, the Log Correlation Engine (LCE) and the Passive Vulnerability Scanner (PVS).

Vulnerability Research Engineer

This position is ideal for those who like to research and test software vulnerabilities. The results of your research will present themselves as Nessus and PVS plugins, which are small scripts that are able to detect vulnerabilities. In this role, you will accurately test for vulnerabilities by manually configuring vulnerable targets in a virtual environment, analyzing the system or application to reliably understand how the vulnerability is exploited and then developing a method to test for the vulnerability with credentialed or uncredentialed access. We are looking for people with strong programming skills (knowledge of a scripting language, regular expressions, functions and source code analysis), familiarity with system configurations in operating systems, applications or network devices and in-depth knowledge of TCP/IP protocols, Linux/Unix internals and Windows internals.

August 5, 2008

As a new Tenable employee, one of my first opportunities was to sit in on recently updated Nessus training classes taught by Tenable’s Training Lead, Matt Franz. Joining me in putting Matt on the hot seat was Tenable CSO Marcus Ranum. As a consultant, I have been using Nessus for almost ten years to assist in assessing clients’ networks, but had never attended formal training on the software. I sat in on the first day of class to better understand how to leverage Nessus to perform credentialed scans to audit a
