Hacker Self-Defense. Techniques for Detecting and Preventing Hacker Attacks

The book is dedicated to practical methods of active cyber defense based on the analysis of attackers' actions and the application of cyber self-defense principles. Approaches to identifying and minimizing attacks at various stages of penetration are discussed—from external reconnaissance to activity within the internal perimeter of the network. It demonstrates how to use protective methods that do not require administrative rights and access to server infrastructure, applicable from the level of an ordinary user. Special attention is given to the analysis of behavioral signs of attacks, detection of traces in domain authentication systems, and methods of countering threats in wireless networks. Techniques for passive and active detection are presented, aimed at minimizing required costs and covering the maximum attack surface of the network infrastructure.
