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

Application profiling


An enterprise organization might have tons of applications designed and built for serving various business purposes. The applications may be small or complex and could be built using various technologies. Now, when it's time to design and implement an enterprise-wide application security program, it really becomes crucial to decide upon the priority for assessment. There might be 100 applications in all; however due to limited resources, it may not be possible to test all 100 of them within the specific duration. This is when application profiling comes handy.

Application profiling involves classifying applications into various criticality groups such as high, medium, and low. Once classified, an assessment priority can then be decided on, based on the group the application belongs to. Some of the factors that help to classify the applications are as follows:

  • What is the type of application (thick client or thin client or mobile app).
  • What is the mode of access (internet...
