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.

What is address spoofing?

In cyber security, address spoofing is the act of disguising a MAC and or LAN IP address to appear to belong to another device. For example, hackers will often spoof their MAC address to disguise their device on a targeted network. By spoofing their MAC address to match a device found on the network, a hacker can blend in as that device. Hackers will also spoof their devices to make it harder for cyber security professionals to determine the origin of attack and what devices were involved. By sending spoofed ARP messages, hackers can manipulate the ARP table. Spoofed ARP messages will allow the attacker's MAC address to be associated with a MAC address of a victim host. Spoofing ARP messages is also known as ARP poisoning. Sometimes, hackers will use ARP poisoning to cause the network to stop communicating. When the ARP table becomes too corrupted, the network no longer knows where...
