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

Threat modeling tools


While threat modeling can be easily done with simple pen and paper, there are some specialized tools available that can ease the overall process. We'll be looking at two such tools that can be used effectively for modeling threats.

Microsoft Threat Modeling Tool

The most widely used tool for threat modeling is the Microsoft Threat Modeling Tool. It is available free of charge to all and can be downloaded from https://www.microsoft.com/en-in/download/details.aspx?id=49168.

Once downloaded and installed, the initial screen looks like this:

Click on Create A Model to get started with designing a new threat model, as shown in the following screenshot. You will be presented with a blank canvas to proceed with designing:

The right-hand pane, as shown in the following screenshot, has all the necessary elements. You can simply drag and drop the required elements into the canvas, as shown in the following screenshot:

Once all the components are added and connected, the threat model...
