  • Mandatory Certification of Network Security Devices

    Mandatory Certification of Network Security Devices

    The EU EN 18031 certification introduces a new era of cybersecurity compliance under the Radio Equipment Directive (RED). This article. Network devices represent one of the core pillars of IoT, enabling the smart “things” to connect and communicate with each other. The standard is highly technical, divided into three detailed parts, and can be challenging to navigate without. From the CCDB established Working Group, the Network Device International Technical Community (ND-iTC) was formed. Since August 1, 2025, these requirements have been in full force.


  • Key Points for Testing Network Security Equipment

    Key Points for Testing Network Security Equipment

    Network security audits help protect sensitive data by evaluating access controls, identifying security weaknesses such as open ports or outdated software, monitoring unauthorized activity, and ensuring compliance with data protection regulations such as GDPR or PCI DSS. This blog is about the top 10 network security testing methodologies that every cybersecurity professional should adopt in 2025. By learning and implementing these, organizations can strengthen their defenses and stay safe from attackers. The sophistication level of cyberattacks is staggering. public companies must disclose any cybersecurity incident they determine to be 'material' within four business days of that determination. Meanwhile, the average. Regular testing, integration with DevOps/CloudOps, combining automation with human expertise, and partnering with experts like Zymr, ensure enterprises stay resilient against evolving AI-driven and cloud-focused threats. Critical areas to focus on include evaluating firewalls, access controls, encryption methods, network segmentation, and patch management.

  • Passive Optical Network Uplink Multiplexing Technology

    Passive Optical Network Uplink Multiplexing Technology

    There are two main types of optical filters, Mux/Demux and Optical Add/Drop Multiplexer (OADM). They are also vendor solution independent since no SW integration is required. The authors have studied WDM-PONs with centralised lightwave source and direct detection, where a wavelength-reuse system is employed to transmit the uplink data by using a colourless transmitter at the optical network unit (ONU). WDM-PON system was demonstrated using a Fabry–Perot laser diode as a. This paper offers a comprehensive review and outline of the prospects of technologies for bringing a beyond-100G PON to practical applications in the future. This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a. Abstract: We propose to use multiple uplinks in passive optical networks (PONs) to increase the optical transmission power from users to central office.
