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.

Summary

In this chapter, we looked at the basics of packet-crafting and sniffing with various Python modules, and saw that scapy is very powerful and easy to use. By now, we have learned the basics of socket programming and scapy. During our security assessments, we may need the raw output and access to basic levels of packet topology so that we can analyze the information and make decisions ourselves. The most attractive part of scapy is that it can be imported and used to create networking tools without going to create packets from scratch.

In the next chapter, we will explore programming packages in Python to extract public information from servers with services such as shodan.
