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.

Summary

After reading this chapter, you should now have a much better understanding of how SQL works and of its vulnerabilities. SQL has revolutionized the way users interact with relational databases, but has come at a great cost to security. As we learned from the attack examples, having weak database protection can lead to devastating results. It is always important to understand the different types of SQL injection attacks. For example, by reading this chapter you can now explain what a union-based SQL injection is and why hackers use this type of attack. Understanding how to recognize the behavior of the different types of attacks can allow for a greater response time to mitigate the attack. Many SQL attacks will go unnoticed until the hackers publicly dump the user data. Remember this can be prevented by actively monitoring for malicious SQL statements. Many companies will find those with SQL knowledge highly...
