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 scapy

The analysis of network traffic is the process by which intercept packets can be intercepted that are exchanged between two hosts, knowing the details of the systems that intervene in the communication. The message and the duration of the communication are some of the valuable information that an attacker who is listening in the network medium can obtain.

What can we do with scapy?

Scapy is a Swiss-army knife for network manipulation. For this reason, it can be used in many tasks and areas:

  • Research in communications networks
  • Security tests and ethical hacking to manipulate the traffic generated
  • Package-capture, processing, and handling
  • Generating packages with a specific protocol...
