Which concept provides a structured view of attacker phases to aid defense by identifying and preventing intrusions?

• A. Cyber War
• B. Cyber Kill Chain Methodology
• C. Electronic Warfare
• D. Hacker warfare

Answer: (B)

Understanding attacker models helps defenders prioritize how and where to block an intrusion. The Cyber Kill Chain Methodology provides a structured view of attacker phases, breaking an intrusion into distinct steps: reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on objectives. By aligning security controls to each phase, you can detect or disrupt an attack early and prevent it from advancing to later stages. This phased perspective supports proactive defense and threat hunting—you look for indicators at each step and implement appropriate measures to shut down the attacker’s progress, ideally before capabilities like installation or control are established. Other terms describe broad concepts of conflict or warfare in cyberspace rather than a concrete, lifecycle-based model for intrusions. Cyber War refers to strategic-level conflict between actors or nations, Electronic Warfare deals with manipulating or exploiting the electromagnetic spectrum, and Hacker warfare is a general notion of conflict involving attackers. None of these offer the actionable, step-by-step framework that helps map defenses to attacker actions in order to prevent intrusions.
