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.

Detection Systems

What is an intrusion system? Typically, it comes in two flavors and a few different types. The basic type is either host based, network-based, or physical; the flavors are intrusion detection system (IDS) and intrusion prevention system (IPS). The goal of these types of devices are generally described as the act of detecting actions that is attempting to compromise the confidentiality, integrity, or availability of an organizations resource. If we are looking at specifics, the goal of intrusion detection is to detect or identify entities attempting to subvert current security controls; while intrusion prevention is similar to detect with the added ability to block or prevent. The key difference between the IDS and IPS is the ability to act.
