Features: The bustling, noisy metropolis, like a tired child, slowly quiets down. The night is so silent it feels suffocating, as if one can hear a series of data streaming over network cables. In the corners of the city, the faint glow of screens illuminates a small room, with intermittent flashes of deep blue in the darkness. One person, one laptop, a cup of coffee that has gone from hot to cold and back again, and a server somewhere unknown—everything continues.
Whenever we hear the word "hacker," these thoughts inevitably come to mind. This book focuses on an in-depth analysis of the intrusion process, introducing readers to how intruders collect information, how they use that information to find entry points into target servers (based on authentication, vulnerabilities, or malware), how they establish remote connections after intrusion, what tasks they perform once inside, how they leave backdoors for future access, and how they clear system logs to avoid detection. Additionally, the book details how intruders achieve stealth protection during the information scanning and intrusion phases, as well as how they evade discovery.
Each step of the intrusion process is analyzed in detail to infer the intruder's objectives and tasks at each stage. Common issues encountered during the process are also explained and addressed. The book also compares and analyzes several common intrusion methods. From both "attack" and "defense" perspectives, using real-world intrusion examples and the author's personal insights, it vividly recreates the entire process of network intrusion and defense.
The book is divided into six chapters, systematically covering the entire intrusion process and corresponding defense measures. It includes information gathering, authentication-based intrusion and defense, vulnerability-based intrusion and defense, malware-based intrusion and defense, stealth techniques during intrusion, leaving backdoors after intrusion, and footprint clearing techniques. Using illustrations, the book analyzes each step of the intrusion to speculate on the intruder's motives. It explains common issues encountered during the process and compares and analyzes common intrusion methods to help readers understand the tactics used by intruders and defend against them effectively.
This book is suitable for network technology enthusiasts, network system administrators, as well as students and reference materials for related fields.
