Digital biomarkers are objective, quantifiable physiological and behavioral data collected through digital devices such as smartphones, wearable sensors, and connected medical tools. Unlike traditional biomarkers, which often rely on laboratory tests or in-clinic measurements, digital biomarkers are generated continuously in real-world settings. They capture signals like heart rhythm, physical activity, sleep patterns, voice characteristics, typing behavior, and movement dynamics, transforming everyday interactions with technology into health insights.Shifting from Occasional Treatment to Ongoing MonitoringTraditional health monitoring is typically episodic, based on occasional clinic visits and short diagnostic tests. Digital biomarkers shift this model toward continuous observation. Wearable devices can track heart…

Software supply-chain attacks have evolved from a niche worry into a major force reshaping contemporary software engineering, as adversaries exploit the trusted tools, libraries, and services developers rely on, enabling a single vulnerability to expose countless organizations, while high-profile breaches in recent years have transformed how teams architect, create, and sustain software, driving security considerations much earlier and more deeply into the entire development process.Gaining Insight into Software Supply-Chain AttacksA software supply-chain attack occurs when attackers infiltrate the development or distribution process rather than directly attacking the end application. Instead of breaking into a single system, they compromise shared components…
