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

Though most of the professional vulnerability assessment is conducted in quite a controlled manner, there still remains the possibility of something becoming disruptive. In such a case, preapproved support from senior management is crucial.

An NDA is one of the most important documents that a VA tester has to sign before the test begins. This agreement ensures that the test results are handled with high confidentiality and the findings are disclosed only to authorized stakeholders. An organization's internal vulnerability assessment team might not require the signing of an NDA for each and every test, however, it is absolutely required for any test being conducted by an external team.
