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 metadata from images

In this section, we review how to extract EXIF metadata from images with the PIL module.

Introduction to Exif and the PIL module

One of the main modules that we find within Python for the processing and manipulation of images is PIL. The PIL module allows us to extract the metadata of images in EXIF.

Exif (Exchange Image File Format) is a specification that indicates the rules that must be followed when we are going to save images and defines how to store metadata in image and audio files. This specification is applied today in most mobile devices and digital cameras.

The PIL.ExifTags module allows us to extract information from these tags:

We can see the official documentation for the exiftags...
