Securing Network Infrastructure

By: Sairam Jetty, Sagar Rahalkar

Overview of this book

Digitization drives technology today, which is why it’s so important for organizations to design security mechanisms for their network infrastructures. Analyzing vulnerabilities is one of the best ways to secure your network infrastructure. This Learning Path begins by introducing you to the various concepts of network security assessment, workflows, and architectures. You will learn to employ open source tools to perform both active and passive network scanning and use these results to analyze and design a threat model for network security. With a firm understanding of the basics, you will then explore how to use Nessus and Nmap to scan your network for vulnerabilities and open ports and gain back door entry into a network. As you progress through the chapters, you will gain insights into how to carry out various key scanning tasks, including firewall detection, OS detection, and access management to detect vulnerabilities in your network. By the end of this Learning Path, you will be familiar with the tools you need for network scanning and techniques for vulnerability scanning and network protection. This Learning Path includes content from the following Packt books: •Network Scanning Cookbook by Sairam Jetty •Network Vulnerability Assessment by Sagar Rahalkar

Vulnerability assessments using OpenVAS


Now that we have got familiar with enumeration, the next logical step is performing vulnerability assessments. This includes probing each service for possible open vulnerabilities. There are many tools, both commercial as well as open source, available for performing vulnerability assessments. Some of the most popular tools are Nessus, Nexpose, and OpenVAS.

OpenVAS is a framework consisting of several tools and services that provide an effective and powerful vulnerability management solution. More detailed information on the OpenVAS framework is available at http://www.openvas.org/.

The latest Kali Linux distribution doesn't come with OpenVAS by default. Hence, you need to manually install and set up the OpenVAS framework. Following is the set of commands that you can use to set up the OpenVAS framework on Kali Linux or any Debian-based Linux distribution:

root@kali:~#apt-get update
root@kali:~#apt-get install openvas
root@kali:~#openvas-setup
