Python: Penetration Testing for Developers

By: Christopher Duffy, Mohit , Cameron Buchanan, Andrew Mabbitt, Terry Ip, Dave Mound, Benjamin May

Overview of this book

Cybercriminals are always one step ahead, when it comes to tools and techniques. This means you need to use the same tools and adopt the same mindset to properly secure your software. This course shows you how to do just that, demonstrating how effective Python can be for powerful pentesting that keeps your software safe. Comprising of three key modules, follow each one to push your Python and security skills to the next level. In the first module, we’ll show you how to get to grips with the fundamentals. This means you’ll quickly find out how to tackle some of the common challenges facing pentesters using custom Python tools designed specifically for your needs. You’ll also learn what tools to use and when, giving you complete confidence when deploying your pentester tools to combat any potential threat. In the next module you’ll begin hacking into the application layer. Covering everything from parameter tampering, DDoS, XXS and SQL injection, it will build on the knowledge and skills you learned in the first module to make you an even more fluent security expert. Finally in the third module, you’ll find more than 60 Python pentesting recipes. We think this will soon become your trusted resource for any pentesting situation. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Learning Penetration Testing with Python by Christopher Duffy ? Python Penetration Testing Essentials by Mohit ? Python Web Penetration Testing Cookbook by Cameron Buchanan,Terry Ip, Andrew Mabbitt, Benjamin May and Dave Mound

Chapter 2. Scanning Pentesting

Network scanning refers to a set of procedures that investigate a live host, the type of host, open ports, and the type of services running on the host. Network scanning is a part of intelligence gathering by virtue of which an attack can create a profile of the target organization.

In this chapter, we will cover the following topics:

  • How to check live systems

  • Ping sweep

  • TCP scanner

  • How to create an efficient IP scanner

  • Services running on the target machine

  • The Concept of a port scanner

  • How to create an efficient port scanner

You should have basic knowledge of the TCP/IP layer communication. Before proceeding further, the concept of the Protocol Data Unit (PDU) should be clear.

PDU is a unit of data specified in the protocol. It is the generic term for data at each layer.

  • For the application layer, PDU indicates data

  • For the transport layer, PDU indicates a segment

  • For the Internet or the network layer, PDU indicates a packet

  • For the data link layer or network access layer...
