This book starts by exploring the basics of networking with Python and then proceeds to network and wireless pen-testing, including information gathering and attacking.

      Who this book is for

      If you are a Python programmer, a security researcher, or a network admin who has basic knowledge of Python programming and want to learn about penetration testing with the help of Python, this book is ideal for you. Even if you are new to the field of ethical hacking, this book can help you find the vulnerabilities in your system so that you are ready to tackle any kind of attack or intrusion.

      What this book covers

      Chapter l, Python with Penetration Testing and Networking, goes through the prerequisites of the following chapters. This chapter also discusses the socket and its methods. The server socket's method defines how to create a simple server.

      Chapter 2, Scanning Pen-testing, covers how to perform network scanning to gather information on a network, host, and the services that are running on the hosts. You will see a very fast and efficient IP scanner.

      Chapter 3, Sniffing and Penetration Testing, teaches how to perform active sniffing and how to create a Transport layer sniffer. You will learn special kinds of scanning.

      Chapter 4, Network Attacks and Prevention, outlines different types of network attacks, such as DHCP starvation and switch mac flooding. You will learn how to detect a torrent on the client side.

      Chapter 5, Wireless Pen-testing, goes through wireless frames and explains how to obtain information such as SSID, BSSID, and the channel number from a wireless frame using a Python script. In this type of attack, you will learn how to perform pen-testing attacks on the AP.

      Chapter 6, Honeypot – Building Traps for Attackers, focuses on how to build a trap for attackers. You will learn how to build code from TCP layer 2 to TCP layer 4.

      Chapter 7, Foot Printing a Web Server and a Web Application, dives into the importance of a web server signature, email gathering, and why knowing the server signature is the first step in hacking.

      Chapter 8, Client-Side and DDoS Attacks, explores client-side validation and how to bypass client-side validation. This chapter covers the implantation of four types of DDoS attacks.

      Chapter 9, Pen-testing SQL and XSS, discusses two major web attacks: SQL injection and XSS. In SQL injection, you will learn how to find the admin login page using a Python script.

      To get the most out of this book

      In order to understand the book reader must have the knowledge of Networking fundamentals, basic knowledge of Linux OS, good knowledge of information security and core Python.

      In order to perform experiments or run the codes reader can use the virtual machine (VMware, virtual box). For Wireless pen-testing readers can use a wireless card TP-Link TL- WN722N. Because TL-WN722N wireless card supports the Kali Linux in VMware.

      Also, never use your own system unless and until you are sure of your techniques and about the tools. Here, in this book I’ve used the system of my friend Mohit to demonstrate all the techniques as his system already had all the necessary tools required and working properly.

      Conventions used

      There are a number of text conventions used throughout this book.

      CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: Mount the downloaded WebStorm–lO*.dmg disk image file as another disk in your system.

      A block of code is set as follows:

      import os

      response = os.popen('ping –n l lO.O.O.l') for line in response.readlines():

      print line,

      When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

      s = socket.socket(socket.PF_PACKET, socket.SOCK_RAW, socket.ntohs(OxO8OO)) i = l

      Any command-line input or output is written as follows: python setup.py install

      Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."

      Warnings or important notes appear like this.

      Tips and tricks appear like this.

      ​Penetration (pen) tester and hacker are similar terms. The difference is that penetration testers work for an organization to prevent hacking attempts, while hackers hack for any purpose such as fame, selling vulnerability for money, or to exploit the vulnerability of personal enmity.

      Lots of well-trained hackers have got jobs in the information security field by hacking into a system and then informing the victim of their security bug(s) so that they might be fixed.

      A hacker is called a penetration tester when they work for an organization or company to secure its system. A pen-tester performs hacking attempts to break into the network after getting legal approval from the client and then presents a report of their findings. To become an expert in pen-testing, a person should have a deep knowledge of the concepts of their technology. In this chapter, we will cover the following topics:

      The scope of pen-testing

      The need for pen-testing

      Components to be tested

      Qualities of a good pen-tester

      Approaches to pen-testing

      Useful Socket Methods Introducing the scope of pen-testing​​

      In simple words, penetration testing is used to test the information security measures of a company. Information security measures entail a company's network, database, website, public-facing servers, security policies, and everything else specified by the client. At the end of the day, a pen-tester must present a detailed report of their findings such as weaknesses, vulnerabilities in the company's infrastructure, and the risk level of particular ​vulnerabilities, and provide solutions if possible.

      ​The need for pen-testing

      There are several points that describe the significance of pen-testing:

      Pen-testing identifies the threats that might expose the confidentiality of an organization

      Expert pen-testing provides assurance to the organization with a complete and detailed assessment of organizational security

      Pen-testing assesses the network's efficiency by producing a huge amount of traffic and scrutinizes the security of devices such as firewalls, routers, and switches

      Changing or upgrading the existing infrastructure of software, hardware, or network design might lead to vulnerabilities that can be detected by pen-testing

      In today's world, potential threats are increasing significantly; pen-testing is a proactive exercise to minimize the chances of being exploited

      Pen-testing ensures whether suitable security policies are being followed or not

      Consider the example of a well-reputed e-commerce company that makes money from an online business. A hacker or a group of black hat hackers find a vulnerability in the company's website and hack it. The amount of loss the company will have to bear will be tremendous.

      ​Components to be tested

      An organization should conduct a risk assessment operation before pen-testing; this will help identify the main threats such as misconfiguration or vulnerability in:

      Routers, switches, or gateways

      Public-facing systems; websites, DMZ, email servers, and remote systems DNS, firewalls, proxy servers, FTP, and web servers

      Testing should be performed on all hardware and software components of a network ​security system.

      ​Qualities of a good pen-tester

      The following points describe the qualities of a good pen-tester. They should:

      Choose a suitable set of tests and tools that balance cost and benefits Follow suitable procedures with proper planning and documentation

      Establish the scope for each penetration test, such as objectives, limitations, and the justification of procedures

      Be ready to show how to exploit the vulnerabilities that they find

      State the potential risks and findings clearly in the final report and provide methods to mitigate the risk(s) if possible

      Keep themselves updated at all times because technology is advancing rapidly

      A pen-tester tests the network using manual techniques or the relevant tools. There are lots of tools available on the market. Some of them are open source and some of them are highly expensive. With the help of programming, a programmer can make his/her own tools. By creating your own tools, you can clear your concepts and also perform more R&D. If you are interested in pen-testing and want to make your own tools, then the Python
