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

Importance of web application security testing

Long ago, organizations used to deploy and work on thick clients. However, now, as we are shifting more toward mobility and ease of access, thin clients (web applications) are in high demand. The same web application, once hosted, can be accessed via multiple endpoints such as a PC, a smartphone, a tablet, and so on. But this has certainly increased the risk factor. Even a single vulnerability in the web application can have devastating effects on the entire organization. Also, as the network and infrastructure security evolved, web applications became easy targets for intruders to gain access inside the organization. Web application security testing is much more than just running an automated scanner to discover vulnerabilities. The automated scanner would not take procedural aspect a into consideration and would also report many false positives.
