Mastering Python for Networking and Security

By: José Ortega

Overview of this book

It’s becoming more and more apparent that security is a critical aspect of IT infrastructure. A data breach is a major security incident, usually carried out by just hacking a simple network line. Increasing your network’s security helps step up your defenses against cyber attacks. Meanwhile, Python is being used for increasingly advanced tasks, with the latest update introducing many new packages. This book focuses on leveraging these updated packages to build a secure network with the help of Python scripting. This book covers topics from building a network to the different procedures you need to follow to secure it. You’ll first be introduced to different packages and libraries, before moving on to different ways to build a network with the help of Python scripting. Later, you will learn how to check a network’s vulnerability using Python security scripting, and understand how to check vulnerabilities in your network. As you progress through the chapters, you will also learn how to achieve endpoint protection by leveraging Python packages along with writing forensic scripts. By the end of this book, you will be able to get the most out of the Python language to build secure and robust networks that are resilient to attacks.

Extracting information from servers with Shodan

In this section, you will learn the basics of Shodan for obtaining information from port scanning, banner servers, and operating system versions. Instead of indexing the web content, it indexes information about headers, banners, and operating system versions.

Introduction to Shodan

Shodan is an acronym for Sentient Hyper-Optimized Data Access Network. Unlike traditional search engines that crawl the web to display results, Shodan attempts to grab data from ports. The free version provides 50 results. If you know how to use it creatively, you can discover the vulnerabilities of a web server.

Shodan is a search engine that lets you find specific information from routers, servers...
