· 3 pulledThe Open Systems Interconnection (OSI) model is more than just a theoretical diagram for IT students; it is the tactical framework for every cybersecurity operation.
By segmenting network communication into seven distinct layers, the OSI model provides a structured approach to identifying attack vectors, diagnosing latency issues, and implementing granular security controls.
For professionals in Security Operations Centers (SOC) or penetration testing, understanding this model is akin to a doctor knowing human anatomy—it tells you exactly where to
