Nmap Essentials : Harness the Power of Nmap, the Most Versatile Network Port Scanner on the Planet, to Secure Large Scale Networks

Nmap is an extremely powerful network port scanner used to identify hosts on a network. Nmap is free, flexible, powerful, and easy to implement, which makes it a very convenient utility. This book demonstrates how to run basic and advanced scans, optimizing them to perform well in a variety of environments. Starting with an overview of Nmap, the reader will be guided through installation on popular operating systems. The book then explains how to use Nmap to run basic and advanced scans in addition to using the Nmap Scripting Engine (NSE). All this helps with optimizing Nmap performance in a variety of environments, eventually enabling the reader to integrate with other Nmap tools such as Nessus, Nikto, Burp Suite, and NSE versus NASL scanning. By the end of the book, the reader will have gained essential insights into network security analysis.

About This Book

• This step-by-step guide is packed with real-life examples on indexing data

Who This Book Is For

This book is for developers who want to increase their experience of indexing in Solr by learning about the various index handlers, analyzers, and methods available in Solr. Beginner level Solr development skills are expected.

What You Will Learn

• Get to know the basic features of Solr indexing and the analyzers/tokenizers available
• Index XML/JSON data in Solr using the HTTP Post tool and cURL command
• Work with Data Import Handler to index data from a database
• Use Apache Tika with Solr to index word documents, PDFs, and much more
• Utilize Apache Nutch and Solr integration to index crawled data from web pages
• Update indexes in real-time data feeds
• Discover techniques to index multilanguage and distributed data in Solr
• Combine the various indexing techniques into a real-life working example of an online shopping web application

In Detail

Apache Solr is a widely used, open source enterprise search server that delivers powerful indexing and searching features. These features help fetch relevant information from various sources and documentation.

This fast-paced guide starts by helping you set up Solr. You'll quickly move on to indexing text and boosting the indexing time. Next, you'll focus on basic techniques for indexing a structured data source through Data Import Handler.

Moving on, you will learn techniques to perform real-time indexing and atomic updates. We'll help you set up a cluster of Solr servers that combine fault tolerance and high availability. You will also gain insights into working scenarios of different aspects of Solr and how to use Solr with e-commerce data. By the end of the book, you will be competent and confident working with indexing and will have a good knowledge base to efficiently program elements.
