Applied Network Security

Overview of this book

Computer networks are increasing at an exponential rate and the most challenging factor organisations are currently facing is network security. Breaching a network is not considered an ingenious effort anymore, so it is very important to gain expertise in securing your network. The book begins by showing you how to identify malicious network behaviour and improve your wireless security. We will teach you what network sniffing is, the various tools associated with it, and how to scan for vulnerable wireless networks. Then we’ll show you how attackers hide the payloads and bypass the victim’s antivirus. Furthermore, we’ll teach you how to spoof IP / MAC address and perform an SQL injection attack and prevent it on your website. We will create an evil twin and demonstrate how to intercept network traffic. Later, you will get familiar with Shodan and Intrusion Detection and will explore the features and tools associated with it. Toward the end, we cover tools such as Yardstick, Ubertooth, Wifi Pineapple, and Alfa used for wireless penetration testing and auditing. This book will show the tools and platform to ethically hack your own network whether it is for your business or for your personal home Wi-Fi.

SQL Injection

This chapter will provide a better understanding of structured query language (SQL) injections and vulnerabilities. The topics covered will include:

  • Learning what hashes are
  • How they function within a network
  • Defining SMB
  • How it operates within a network
  • Learning what an SQL injection is
  • How it is used by attackers
  • Examples of SQL injection methods
  • Learning the basic website vulnerabilities involving injection attacks
  • Defense techniques against SQL injection attacks

In the labs we provide, you will be using Metasploit to pass the hash of a Windows login credential. We will also talk about how a web server databases work and why hackers use SQL injection to steal data from them. This chapter will explore a new type of attack vector that hackers often use to steal credentials from web-server's databases. This chapter will highlight many of the most common SQL vulnerabilities that are exploited...
