NetworkSegmentation

IIoT Security: Protecting Industrial Networks Industrial networks mix OT devices, sensors, PLCs, and business IT. Security must be practical and keep uptime. In IIoT, threats can move quickly across plant floors and data centers, so a steady, repeatable approach works best. Start with a simple plan that emphasizes visibility and resilience. Key risks in IIoT Unsecured devices and weak passwords Poor network segmentation Unpatched software and legacy systems Insufficient visibility and logging Practical steps for protection Start with asset inventory and classify devices by risk and function. Segment networks into zones and enforce strict borders between IT and OT. Apply patch management and firmware updates on a regular schedule. Harden devices: disable unused services, change default credentials, and enable secure boot where possible. Enforce access control and MFA for critical systems and remote access. Monitor for anomalies and maintain baseline behavior across the network. Real-world example A mid-sized plant used a dedicated OT gateway to translate protocols and log events to a central SIEM. With clear segmentation, a malware alert in IT did not spread to the PLCs, reducing downtime while alert teams investigated. ...

IoT Security and Privacy in the Connected World From smart speakers to security cameras, many devices connect to the internet every day. This connected world brings convenience, but also risks. When devices lack strong protection, data can leak, and bad actors may take control. A clear plan helps keep both you and your family safer. Security by design means thinking about protection from the start. For consumers, look for devices that use strong authentication, offer regular updates, and keep data handling clear. For manufacturers, it means building with fewer gaps and providing simple ways to update and review security settings. In both cases, visible safeguards make a big difference. ...
