While it simplifies orchestration, it often obscures the granular reality of network traffic. For the <strong>CyberNEMO<\/strong> project, specifically within <strong>WP2<\/strong>, we move past these high-level views to focus on the <strong>network socket<\/strong>. Why? Because sockets represent the &#8220;ground truth&#8221; of connectivity. In a distributed meta-OS, understanding the real-time state of point-to-point communication is the only way to ensure <strong>Cybersecurity and Privacy by Design<\/strong>.<\/p>\n\n\n\n<p><strong>Capturing the &#8220;Ground Truth&#8221; with White Shark<\/strong><\/p>\n\n\n\n<p>Traditional Kubernetes monitoring often looks at service-level averages, which can mask micro-bursts of latency or intermittent failures. By monitoring at the socket level, our <strong>White Shark<\/strong> probe can collect raw, high-fidelity data\u2014including latency, throughput, and jitter\u2014directly from the source. This allows us to see exactly how data moves between specific pods, bypassing the &#8220;fog&#8221; of virtualized overlays. This level of precision is essential for building a <strong>verifiable data plane<\/strong>, ensuring that every packet follows its intended path without manipulation.<\/p>\n\n\n\n<p><strong>Building a Stronger Zero Trust Foundation<\/strong><\/p>\n\n\n\n<p>Ultimately, focusing on sockets supports the <strong>Zero Trust<\/strong> principle of &#8220;explicit verification&#8221;. In CyberNEMO, we don&#8217;t just trust that a connection is secure because it\u2019s inside the cluster. Instead, we use socket-based telemetry to constantly validate that communication patterns match the intended security policies.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>In a standard Kubernetes (K8s) deployment, the sheer level of abstraction is a double-edged sword.
