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.

How do hackers hide their attack?

Now there is no real defense against zero day attacks. These types of attack are newly coded exploits that haven't been discovered yet and analyzed, and thus haven't yet been added to the database of viruses or malware, from which antivirus software would then create a patch for use as the basis for an update.

A basic way to understand how antivirus software works is simple. Experienced hackers can create their own malware and use it to devastating effect. Malware is always written in codes. Whether that string of codes is a simple one-line exploit or runs to thousands of lines, it will always be unique by virtue of its signature.

What we mean by that is, within malware code there is a unique pattern that can be uncovered.

For example, let's look at the plain text word evade to dissect and analyze it. The word evade as you currently see it, is in text format which...
