Connected and autonomous vehicles (CAVs) represent one of the most transformative innovations of the 21st century, integrating advanced sensors, artificial intelligence, and communication technologies to create smarter, safer, and more efficient transportation systems. At the heart of these systems lies a need for seamless connectivity, enabling vehicles to interact with cloud services, roadside infrastructure, and…

DNS-based on-demand network segmentation and access control represents a transformative approach to managing modern network environments, addressing the challenges posed by increasingly complex and dynamic infrastructures. As organizations adopt hybrid work models, embrace cloud computing, and integrate Internet of Things (IoT) devices into their networks, traditional methods of segmentation and access control struggle to keep…

The evolution of the internet has brought about a complex interplay between traditional Domain Name System (DNS) infrastructure and emerging decentralized naming systems. While traditional DNS has long served as the backbone of internet navigation, enabling the resolution of domain names to IP addresses, decentralized naming systems have introduced new paradigms for managing and accessing…

The Domain Name System (DNS) serves as the cornerstone of internet functionality, enabling the translation of domain names into the IP addresses that power connectivity. In the realm of Unified Communications (UC) and Voice over Internet Protocol (VoIP) systems, DNS assumes an even more critical role, ensuring reliable operation for voice calls, video conferencing, messaging,…

The Secure Access Service Edge (SASE) architecture has emerged as a transformative framework for modern network security, blending wide-area networking (WAN) with a comprehensive suite of security services to create a cloud-native solution for securing distributed environments. As enterprises increasingly adopt remote work, cloud computing, and edge computing, SASE provides a unified model that ensures…

The Domain Name System (DNS) is an indispensable component of internet and network operations, enabling the seamless translation of domain names into IP addresses. For mission-critical enterprise applications, DNS plays an even more pivotal role, as the performance, reliability, and security of these applications often hinge on optimized DNS operations. From real-time financial systems and…

DNS Response Policy Zones (RPZ) have emerged as a powerful tool for advanced threat mitigation, leveraging the ubiquitous nature of the Domain Name System (DNS) to detect and neutralize malicious activity at scale. Introduced as an extension to traditional DNS functionality, RPZ allows administrators to enforce custom response policies based on domain reputation, behavior, and…

The Domain Name System (DNS) is often described as the backbone of the internet, enabling seamless navigation by translating human-readable domain names into machine-readable IP addresses. Its infrastructure underpins virtually every aspect of online activity, from accessing websites and streaming content to enabling complex enterprise networks and cloud services. As the internet continues to evolve,…

The Domain Name System (DNS) is one of the most critical components of internet infrastructure, serving as the foundation for translating human-readable domain names into machine-readable IP addresses. However, its ubiquity and importance also make it a prime target for cyberattacks. DNS threat modeling has emerged as an essential practice for identifying vulnerabilities, understanding potential…
