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

Testing tools

We have already seen a list of various tools earlier in this chapter that we can use for performing web application security testing. In this section, we'll have a brief introduction to two such tools.


OWASP ZAP is a multi-functional tool that can perform an array of tasks related to application security testing. It is capable of doing automated scanning as well and is extremely effective in manual testing and fuzzing. OWASP ZAP can be downloaded from

The following image shows the initial OWASP ZAP console. The left pane displays the site hierarchy, the right pane displays individual requests and responses, and the bottom pane displays active scans:



We can either first crawl the application or directly enter the URL to attack as shown in the following image. We can see the active scan in the bottom pane and, once it is completed, we can simply click the Report menu and select Generate HTML Report.
