Cybersecurity – Attack and Defense Strategies - Second Edition

By: Yuri Diogenes, Dr. Erdal Ozkaya

Overview of this book

Cybersecurity – Attack and Defense Strategies, Second Edition is a completely revised new edition of the bestselling book, covering the very latest security threats and defense mechanisms including a detailed overview of Cloud Security Posture Management (CSPM) and an assessment of the current threat landscape, with additional focus on new IoT threats and cryptomining. Cybersecurity starts with the basics that organizations need to know to maintain a secure posture against outside threat and design a robust cybersecurity program. It takes you into the mindset of a Threat Actor to help you better understand the motivation and the steps of performing an actual attack – the Cybersecurity kill chain. You will gain hands-on experience in implementing cybersecurity using new techniques in reconnaissance and chasing a user’s identity that will enable you to discover how a system is compromised, and identify and then exploit the vulnerabilities in your own system. This book also focuses on defense strategies to enhance the security of a system. You will also discover in-depth tools, including Azure Sentinel, to ensure there are security controls in each network layer, and how to carry out the recovery process of a compromised system.

Reconnaissance

This is the first step of the kill chain. In cyber attacks, Threat Actors spend some time gathering information that they can use to attack a target. This information includes the hosts connected on a network, and the vulnerabilities in the network or any of the devices connected to it. There are two techniques of conducting reconnaissance; active information gathering and passive information gathering.

In active information gathering, the Threat Actor will interact with a target system to find out its exploitable vulnerabilities. For instance, a Threat Actor could do port scanning on a host connected to a network. The end goal of this exercise will be to find out the open ports that can be exploited.

On the other hand, passive information gathering is whereby a Threat Actor does reconnaissance without interacting with the target system. For instance, Google hacking is a passive information gathering exercise where the Threat Actor uses advanced Google queries...
