Embracing an Operation-Centric Security Model for Modern Threat Defense

This article discusses the shift from traditional, reactive cybersecurity models focused on Indicators of Compromise (IOCs) to a more proactive, operation-centric approach that emphasizes Indicators of Behavior (IOBs). It explores the limitations of traditional models, the advantages of the operation-centric model, the necessary technology stack, implementation considerations, and the key roles and skills required for successful operation. The article advocates for understanding the "attack narrative" and utilizing frameworks like MITRE ATT&CK to proactively defend against modern cyber threats.
