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.

Capturing and injecting packets with pcapy

In this section, you will learn the basics of pcapy and how to capture and read headers from packets.

Introduction to pcapy

Pcapy is a Python extension module that interfaces with the libpcap packet capture library. Pcapy enables Python scripts to capture packets on the network. Pcapy is highly effective when used in conjunction with other collections of Python classes for constructing and packet-handling.

You can download the source code and the latest stable and development version at https://github.com/CoreSecurity/pcapy.

To install python-pcapy on the Ubuntu linux distribution, run the following commands:

sudo apt-get update
