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.

What defences are there against hash password attacks?

Defending against pass the hash attacks it not very hard.

Password policies should be routinely updated to provide the strongest security possible. Many users will not like changing their passwords constantly, but it could make the difference in preventing a pass the hash attack. When creating a strong password, it is more important to choose length over complexity. A password over 15 characters is much harder to crack than a more complex password using eight characters. It is also important that passwords are never reused for other locations. The password policies should be stronger for domain accounts. Password management software can be helpful.
