NIST updates its DNS security guidance for the first time in over a decade

DNS infrastructure underpins nearly every network connection an organization makes, yet security configurations for it have gone largely unrevised at the federal guidance level for more than twelve years. NIST published SP 800-81r3, the Secure Domain Name System Deployment Guide, superseding a version that dates to 2013. The document covers three main areas: using DNS as an active security control, securing the DNS protocol itself, and protecting the servers and infrastructure that run DNS services. … More → The post NIST updates its DNS security guidance for the first time in over a decade appeared first on Help Net Security.

Week in review: ScreenConnect servers open to attack, exploited Microsoft SharePoint flaw

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: What smart factories keep getting wrong about cybersecurity In this Help Net Security interview, Packsize CSO Troy Rydman breaks down the biggest vulnerabilities in smart factory environments today, from IoT devices and legacy systems to human error. He explains how unmanaged devices, from sensors to robotic components, often go unpatched and become entry points for attackers. Certificate lifespans are shrinking … More → The post Week in review: ScreenConnect servers open to attack, exploited Microsoft SharePoint flaw appeared first on Help Net Security.

Harvard engineers build chip that can twist and control light in real time

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light’s “handedness” behaves. This allows the chip to distinguish between left- and right-circular polarized light with remarkable precision. The advance could lead to smarter sensors, faster communications, and new quantum technologies.
