Overview of this book

Python’s latest updates add numerous libraries that can be used to perform critical security-related missions, including detecting vulnerabilities in web applications, taking care of attacks, and helping to build secure and robust networks that are resilient to them. This fully updated third edition will show you how to make the most of them and improve your security posture. The first part of this book will walk you through Python scripts and libraries that you’ll use throughout the book. Next, you’ll dive deep into the core networking tasks where you will learn how to check a network’s vulnerability using Python security scripting and understand how to check for vulnerabilities in your network – including tasks related to packet sniffing. You’ll also learn how to achieve endpoint protection by leveraging Python packages along with writing forensics scripts. The next part of the book will show you a variety of modern techniques, libraries, and frameworks from the Python ecosystem that will help you extract data from servers and analyze the security in web applications. You’ll take your first steps in extracting data from a domain using OSINT tools and using Python tools to perform forensics tasks. By the end of this book, you will be able to make the most of Python to test the security of your network and applications.

Extracting geolocation information

One way to obtain geolocation from an IP address or a domain is by using a service that provides location data such as the country, latitude, and longitude. Among the services that provide this information in an easy way, hackertarget.com is a popular service with quality location data (https://hackertarget.com/geoip-ip-location-lookup). This service also provides a REST API for obtaining geolocation from an IP address using the https://api.hackertarget.com/geoip/?q=8.8.8.8 endpoint:

IP Address: 8.8.8.8
Country: United States
State: California
City: Los Angeles
Latitude: 34.0544
Longitude: -118.2441

We can use similar services to get geolocation, such as https://ip-api.com. This service provides an endpoint to get geolocation by IP address: http://ip-api.com/json/8.8.8.8. In the following script, we are using this service and the requests module to obtain a JSON response with geolocation information. You can find the following code in the...
