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

Penetration testing standards

Penetration testing is not just a single activity, but a complete process. There are several standards available that outline steps to be followed during a penetration test. This section aims at introducing the penetration testing lifecycle in general and some of the industry-recognized penetration testing standards.

Penetration testing lifecycle

Penetration testing is not just about using random tools to scan the targets for vulnerabilities, but a detail-oriented process involving multiple phases. The following diagram shows various stages of the penetration testing lifecycle:


  1. Information gathering phase: The information gathering phase is the first and most important phase of the penetration testing lifecycle. Before we can explore vulnerabilities on the target system, it is crucial to gather information about the target system. The more information you gather, the greater is the possibility of successful penetration. Without properly knowing the target system...
