Nmap 6: Network Exploration and Security Auditing Cookbook

Overview of this book

Nmap is a well known security tool used by penetration testers and system administrators. The Nmap Scripting Engine (NSE) has added the possibility to perform additional tasks using the collected host information. Tasks like advanced fingerprinting and service discovery, information gathering, and detection of security vulnerabilities."Nmap 6: Network exploration and security auditing cookbook" will help you master Nmap and its scripting engine. You will learn how to use this tool to do a wide variety of practical tasks for pentesting and network monitoring. Finally, after harvesting the power of NSE, you will also learn how to write your own NSE scripts."Nmap 6: Network exploration and security auditing cookbook" is a book full of practical knowledge for every security consultant, administrator or enthusiast looking to master Nmap. The book overviews the most important port scanning and host discovery techniques supported by Nmap. You will learn how to detect mis-configurations in web, mail and database servers and also how to implement your own monitoring system. The book also covers tasks for reporting, scanning numerous hosts, vulnerability detection and exploitation, and its strongest aspect; information gathering.

Matching services with known security vulnerabilities


Version discovery is essential to pen-testers as they can use this information to find public security vulnerabilities affecting a scanned service. The Nmap Scripting Engine allows us to match the popular OSVDB vulnerability database with the discovered services in our scans.

This recipe shows how to list known security vulnerabilities in the osvdb database that could possibly affect a service discovered by using Nmap.

Getting ready

To accomplish this task, we use the NSE script vulscan developed by Marc Ruef. This script is not included in the official Nmap repository, so you need to install it separately before continuing.

To install it, download the latest version of vulscan from http://www.computec.ch/mruef/?s=software&l=e.

After extracting the files, copy the script vulscan.nse in your local script folder ($NMAP_INSTALLATION/scripts/). Then create a folder named vulscan in the same directory and place the osvdb database files object_products...
