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 terminology

Before we get into the details of how to model threats, we must become familiar with some common terms used throughout the process of threat modeling. Some common terms are as follows:

  • Asset: An asset can be any resource that is valuable. The asset can be tangible or intangible. For example, a mainframe computer in a data center may be a tangible asset while the reputation of an organization may be an intangible asset.
  • Attack: An attack is something that happens when an actor or a threat agent takes action utilizing one or more vulnerabilities in the system. For example, an application session hijacking attack might happen when someone exploits a cross-site scripting vulnerability to steal user cookies and session IDs.
  • Attack vector: An attack vector is a path taken by the attacker in order to successfully compromise the system. For example, an email with a malicious attachment sent to the victim could be one possible attack vector.
  • Attack surface: An attack surface...
