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

Security hardening and secure configuration reviews


When we see an application running in our web browser, it is just the tip of the iceberg. There is lot of underlying infrastructure that is supporting the application, which typically includes a web server, database server, operating system, and so on. So, even if the end application is made very secure, it might be possible that the underlying infrastructure components have vulnerabilities, allowing attackers to compromise the system. This is where security hardening comes into picture.

In order to secure the complete application ecosystem, which includes the underlying infrastructure, it is essential to perform secure configuration reviews for all the participating components and harden the security accordingly. A simple way to achieve this could be going through configuration files for each component and then configuring items that are relevant to security. Another better approach could be using industry standard benchmarks for secure...
