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.

Introducing port scanning with Nmap

In this section, we review the Nmap tool for port scanning and the main scanning types that it supports. We will learn about Nmap as a port scanner that allows us to analyze the ports and services that run on a machine.

Introducing to port scanning

Once I have identified endpoints within our network, the next step is to perform a port scan. Computers that support communication protocols utilize ports in order to make connections. In order to support different conversations with multiple applications, ports are used to distinguish various communications in the same machine or server. For example, web servers can use the Hypertext Transfer Protocol (HTTP) to provide access to a web page which...
