← Department of Defense Interview Insights
I knew this conceptually but fumbled the sequencing out loud.
Start by defining the cyber kill chain as a model for understanding and disrupting cyber attacks, then walk through its seven stages. For a software engineering role at the DoD, emphasize how each stage maps to defensive measures and system design considerations, such as logging, access control, and network segmentation.
Pro tip: Tie the kill chain to the DoD's 'defense in depth' strategy and mention that breaking the chain at any stage can prevent an attack, showing you understand how to prioritize security investments.
Explain that it's a seven-stage model developed by Lockheed Martin to describe the lifecycle of a cyber attack, from reconnaissance to actions on objectives.
Briefly name each stage: Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control, and Actions on Objectives.
Provide a one-sentence description of each stage, focusing on what happens and how defenders can detect or disrupt it.
Discuss how software engineers can implement controls at each stage, such as secure coding to prevent exploitation, logging for detection, and least privilege to limit actions on objectives.
Highlight the importance of the kill chain in military systems, where defense in depth and resilience are critical, and mention frameworks like NIST or MITRE ATT&CK that complement it.
