Dell expands security stack with quantum-ready protections and AI threat detection

Dell Technologies has introduced new security by design and cyber resilience capabilities to help organizations secure, detect and recover from next-generation threats. The enhancements address emerging risks from quantum computing and AI by hardening device foundations, strengthening cyber resilience when incidents occur and extending threat detection into AI data platforms. Why it matters AI is creating more valuable data and giving attackers new ways to move faster. Quantum computing will accelerate that shift by weakening … More → The post Dell expands security stack with quantum-ready protections and AI threat detection appeared first on Help Net Security.

GitHub just made it much harder to ship a vulnerable pull request

GitHub is expanding its application security capabilities with AI-powered security detections designed to identify risks earlier in the development process, with public preview planned for early Q2. The update is intended to improve code scanning, secret detection, and dependency analysis within repositories hosted on the platform. The company said the new detections are designed to complement its existing CodeQL engine, which remains in use for semantic analysis of supported languages. Static analysis continues to play … More → The post GitHub just made it much harder to ship a vulnerable pull request appeared first on Help Net Security.

New light trap design supercharges atom-thin semiconductors

Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a crystal, they created miniature “light traps” that dramatically boost brightness and optical effects—up to 20 times stronger emission and 25 times stronger nonlinear signals. These hollow structures, called Mie voids, concentrate light exactly where the material sits, overcoming a major limitation of atomically thin devices.
