The Domain Name System (DNS) serves as a cornerstone of internet functionality, enabling the resolution of human-readable domain names into machine-readable IP addresses. However, its critical role also makes it a target and tool for cyber threats. From malware communication to phishing schemes and Distributed Denial of Service (DDoS) attacks, DNS is frequently leveraged by…

The Domain Name System (DNS) plays a critical role in the functionality of the internet, serving as the intermediary that translates human-readable domain names into machine-readable IP addresses. Despite its centrality, DNS is often an overlooked component of online performance, with latency in DNS resolution having a significant impact on user experience. In complex global…

The Internet of Things (IoT) is transforming the digital landscape, connecting billions of devices that range from smart home appliances and wearable health monitors to industrial sensors and autonomous vehicles. Each of these devices requires a unique identifier to communicate effectively across networks, and the Domain Name System (DNS), with its robust and scalable design,…

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…

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,…

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…

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…

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)…

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…

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…
