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 attacks remain common and continue to cause problems for many organizations. There are some great methods to defend against SQL injection that every cyber security professional should be aware of. We will discuss the five best ways to defend against SQL injection attacks:

  • The second method is to suppress error messages. Hackers will often use error messages for reconnaissance. If the messages are at least kept local, it can prevent the hacker from learning too much about the structure of the database.
  • The three method is to constantly monitor SQL statements from database-connected applications. It is important to constantly watch for malicious SQL statements so the attack can be...
