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 misconfiguration

We may take a lot of efforts in securing the application. However applications cannot work in isolation. Running an application, requires a lot of supporting components such as web server, database server, and more. If the application isn't securely configured with all these supporting components, many vulnerabilities will be opened for potential attackers. So, the application should not only be developed securely, but should also be deployed and configured securely.

OWASP mapping

Security misconfiguration related vulnerabilities are part of the OWASP Top 10 2017. They are covered under A6:2017 Security Misconfiguration. Some of the vulnerabilities listed under this category are as follows:

  • Security hardening not done on the application stack.
  • Unnecessary or unwanted features are enabled or installed (for example, ports, services, admin pages, accounts, or privileges). The following image shows the default Tomcat page accessible to all users:
  • Application default accounts...
