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

Business logic flaws


Business logic is at the core of the application and decides how an application is expected to behave. Business logic is mainly derived from the objective/aim of the application and is contained mainly in the server side code of the application. If the business logic has some flaws or shortcomings, they can be seriously misused by the attackers. Automated security scanners are not really capable of finding business logic-related issues since they cannot understand the context of the application as humans do. So foolproof business logic along with stringent validation is absolutely required to build a secure web application. 

Testing for business logic flaws

As mentioned earlier, business logic-related flaws cannot be tested comprehensively using automated tools. The following are some guidelines to test business logic:

  • Have a brainstorming session with the application architect, the business users of the application, and the developer to understand what the application...
