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.

Questions

As we conclude, here is a list of questions for you to test your knowledge regarding this chapter’s material. You will find the answers in the Assessments section of the Appendix:

  1. Which method from the PortScanner class is used to perform scans synchronously?
  2. Which method from the PortScanner class is used to perform scans asynchronously?
  3. How can we launch an asynchronous scan on a given host and port if we initialize the object with the self.portScannerAsync = nmap.PortScannerAsync() instruction?
  4. How can we launch a synchronous scan on a given host and port if we initialize the object with the self.portScanner = nmap.PortScanner() instruction?
  5. Which function is necessary to define when we perform asynchronous scans using the PortScannerAsync() class?
