This Book, an excerpt from "Linux For Hacking", is a guide for Linux system administrators on how to secure their systems from hackers. The guide covers a wide range of topics, including network configuration, firewall management, user permissions, and log analysis. The author emphasizes the importance of adopting a "less is more" approach to security by minimizing unnecessary services and access rights. The guide is primarily theoretical but also includes practical tips and examples for implementing the described techniques. It provides detailed information on various security threats, including backdoors, buffer overflows, and Denial-of-Service attacks, and offers solutions for preventing and mitigating these risks. The author stresses that achieving complete security is impossible, but with careful configuration and vigilance, administrators can significantly increase the resilience of their systems against malicious attacks.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cyber_security_summaryDiscover our free courses in tech and cybersecurity, Start learning today:https://linktr.ee/cybercode_academy
