The MITRE ATT&CK Framework is a globally recognized knowledge base that categorizes adversary behaviors into 14 tactical objectives, each representing a distinct phase or goal in a cyber attack lifecycle. This chapter delves into these tactics with a specialized focus on Linux systems—a cornerstone of modern servers, cloud infrastructure, and enterprise environments. Linux’s open-source nature, widespread deployment, and unique architecture make it a prime target for adversaries, necessitating a nuanced understanding of how ATT&CK tactics manifest in this ecosystem. For each tactic, we explore its purpose, Linux-specific techniques, real-world examples, and robust defensive strategies, providing cybersecurity professionals with a comprehensive toolkit to detect, investigate, and mitigate threats.
