Applied Network Security

By: Arthur Salmon, Michael McLafferty, Warun Levesque

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.

Cross site scripting (XSS) attacks

These web application security vulnerabilities enable attackers to inject client-side script in web pages. They often occur when data enters through from an untrusted source, and also dynamic content that's sent to users without validation for malicious content. The implementation for these types of attacks ranges widely, but private transfer of cookies, sessions, sensitive data, and redirection are some things that cross-site scripting is capable of. XSS attacks are commonly either stored or reflected. Stored XSS is where user input is stored on the server, and then a victim is able to retrieve the stored data from the web app without that data being made safe to render in the browser. Reflected XSS is when user input is immediately returned by a web app in an error message, or any response with some or all input from the user, without that data being made safe to render...
