In modern software development, Continuous Integration and Continuous Deployment (CI/CD) pipelines have become indispensable for accelerating development cycles and ensuring high-quality releases. As applications grow more complex and distributed, their reliance on reliable Domain Name System (DNS) configurations intensifies. DNS is critical for routing traffic, connecting services, and maintaining application availability. Yet, DNS misconfigurations or…

The rapid expansion of the Internet has introduced an immense variety of domains, from legitimate business websites to malicious actors intent on phishing, malware distribution, and other cybercrimes. In this environment, determining the trustworthiness of a domain has become critical to protecting users, organizations, and networks. Domain reputation systems, powered by DNS, have emerged as…

The Domain Name System (DNS) is a fundamental component of Internet functionality, acting as a translator between human-readable domain names and machine-readable IP addresses. While its critical role ensures the smooth operation of online services, DNS has also become a prime target for cyberattacks. From cache poisoning to DNS tunneling and Distributed Denial of Service…

The Domain Name System (DNS) is a cornerstone of the Internet, enabling users to connect to websites, applications, and online services by resolving human-readable domain names into machine-readable IP addresses. Given its foundational role, the reliability and availability of DNS are critical to maintaining seamless access to digital resources. Organizations cannot afford downtime or service…

The Domain Name System (DNS) is one of the foundational components of the Internet, enabling users to navigate the web by resolving human-readable domain names into machine-readable IP addresses. At the core of this system lies the DNS root, a globally distributed directory of top-level domains (TLDs) maintained by a centralized governance structure. While the…

Email remains one of the most vital forms of communication in the digital age, yet it continues to face significant challenges in terms of security. Transport Layer Security (TLS) has long been the standard for encrypting email in transit, protecting messages from interception and tampering. However, traditional TLS relies heavily on third-party certificate authorities (CAs)…

DNS logging is an essential component of network management and security, offering critical insights into system behavior, troubleshooting issues, and detecting malicious activity. However, the practice of logging DNS queries has increasingly come under scrutiny due to privacy concerns. DNS queries can reveal sensitive information about users’ browsing habits, interests, and activities, making them a…

The emergence of TLS 1.3 and encrypted DNS protocols, such as DNS over HTTPS (DoH) and DNS over TLS (DoT), represents a significant milestone in enhancing the privacy and security of Internet communications. These technologies address longstanding vulnerabilities in network protocols by encrypting sensitive data, thereby protecting users from eavesdropping, tampering, and interception. However, their…

The Domain Name System (DNS) is a cornerstone of the modern Internet, enabling seamless communication by translating human-readable domain names into IP addresses. Despite its technical nature, the DNS has become a focal point of discussions on Internet governance, reflecting the interplay between technological innovation, policy-making, and global collaboration. These debates encompass issues of control,…

DNS tunneling represents a significant and evolving threat in the realm of cybersecurity. This technique exploits the Domain Name System (DNS), a critical protocol for translating human-readable domain names into IP addresses, to covertly exfiltrate data or establish unauthorized communication channels. Because DNS is essential for most Internet activity and is often allowed through firewalls…
