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.

Host based

The purpose of a host-based intrusion detection system (HIDS) is to identify behavior on individual hosts which they are installed on. Behaviors typically monitored are attempts to identify unauthorized and anomalous behavior on that specific host. A HIDS typically installed an agent that is used to monitor each system and alerts on local OS and application activity. The locally-installed agent uses a combination or algorithm that uses signatures, rules, and heuristics to identify unauthorized or unusual activity. Keep in mind that a HIDS is an IDS and its role is only passive; meaning that it is only gathering, identifying, logging, and alerting. An example of a HIDS would be Tripwire and open source host-based intrusion detection system (OSSEC), to name just two of many.
