Network Scanning Cookbook

By: Sairam Jetty

Overview of this book

Network scanning is a discipline of network security that identifies active hosts on networks and determining whether there are any vulnerabilities that could be exploited. Nessus and Nmap are among the top tools that enable you to scan your network for vulnerabilities and open ports, which can be used as back doors into a network. Network Scanning Cookbook contains recipes for configuring these tools in your infrastructure that get you started with scanning ports, services, and devices in your network. As you progress through the chapters, you will learn how to carry out various key scanning tasks, such as firewall detection, OS detection, and access management, and will look at problems related to vulnerability scanning and exploitation in the network. The book also contains recipes for assessing remote services and the security risks that they bring to a network infrastructure. By the end of the book, you will be familiar with industry-grade tools for network scanning, and techniques for vulnerability scanning and network protection.

Introduction

In this chapter, we will be going through various recipes regarding the reports that can be generated using Nmap and Nessus. We will also look at a recipe on using Nmap to confirm vulnerabilities that are reported by Nessus. It is always required to confirm the vulnerabilities reported by a scanner, as there are chances of the scanner reporting false positive vulnerabilities. Confirming these vulnerabilities will allow the administrative team to focus on the confirmed vulnerabilities instead of wasting resources on false positives that have been reported. Both Nmap and Nessus generate different formats of reports, allowing the user to make a choice as per their requirements.
