Security in the OSI Layers: Understanding the Network to Defend It

Leave a Comment / Attacks, Cybersecurity /

The OSI model is the conceptual backbone that breaks down the complexity of network communication into seven distinct layers. While real-world environments often rely on the TCP/IP model, OSI remains essential for understanding, classifying, and defending systems against cyberattacks. Each layer represents a specific set of functions but also exposes particular attack vectors and requires

ITDR: Identity Threat Detection and Response in Hybrid and Multi-Cloud Environments

Leave a Comment / Attacks, Blue Team /

The perimeter is dead, or rather, it has mutated. In today’s corporate environments, dominated by hybrid architectures, remote users, cloud services, and interconnected applications, digital identity has become the new security perimeter. This idea, once aspirational, is now a reality driven by the most recent and sophisticated attacks. Threat actors no longer compromise endpoints as
