Semantic-free referencing in linked systems
The Web relies on the Domain Name System (DNS) to resolve the hostname portion of URLs into IP addresses. This marriage-of-convenience enabled the Web's meteoric rise, but the resulting entanglement is now hindering both infrastructures--the Web is overly constrained by the limitations of DNS, and …

Protecting DNS from software errors
… with the availability and robustness of the Domain Name System (DNS) infrastructure. Unfortunately, the DNS suffers from a wide variety of problems arising from implementation errors, including vulnerabilities, bogus queries, and proneness to failure. In this work, we present a preliminary …

ASAP: a low-latency transport layer
… in the underlying network protocols, such as Domain Name System (DNS) and Transmission Control Protocol (TCP). In this work, we introduce ASAP, a new naming and transport protocol that significantly reduces latency by shortcutting DNS requests and eliminating TCP’s three-way handshake (3WH). …

Measuring and Understanding TTL Violations in DNS Resolvers
The Domain Name System (DNS) is a scalable-distributed caching architecture where each DNS records are cached around several DNS servers distributed globally. DNS records include a time-to-live (TTL) value that dictates how long the record can be stored before it's evicted from the cache. TTL holds …

Understanding and defending against internet infrastructures supporting cybecrime operations
… two fundamental Internet protocols; the Domain Name System (DNS) and the Border Gateway Protocol (BGP). A popular countermeasure against cybercriminal infrastructures are Autonomous Systems (AS) reputation systems. Past research efforts have developed several AS reputation systems that …

Proactive Cyberfraud Detection Through Infrastructure Analysis
… practices. The first three are based on the Domain Name System (DNS), which translates host names to IP addresses. We first examine fast-flux, a practice where the association between name and address changes much more frequently than usual. We then investigate the use of DNS wildcards, which …

Understanding Internet Naming: From the Modern DNS Ecosystem to New Directions in Naming
… naming schemes. Creating reliable naming systems requires an up-to-date understanding of the current system's real-world operation.Therefore, our first goal is to understand the modern client-side Domain Name System (DNS) ecosystem through empirical study of both system components and …

Network-Based Detection and Prevention System against DNS-Based Attacks
… the malicious servers and the victims. The domain name system (DNS) protocol is one of these approaches that adversaries use to transfer stolen data outside the organization's network using various forms of DNS tunneling attacks. The main reason for targeting the DNS protocol is because DNS …

Fast flux botnet detection based on adaptive dynamic evolving spiking neural network
… categorised according to their C&C protocols. A Domain Name System (DNS) method known as Fast-Flux Service Network (FFSN) is a special type of botnet that has been engaged by bot herders to cover malicious botnet activities, and increase the lifetime of malicious servers by quickly changing the …

Improving Internet Security through Empirical and Qualitative Studies of Email and DNS Ecosystem
Email and the Domain Name System (DNS) remain foundational pillars of Internet communication, yet their security mechanisms continue to suffer from subtle design limitations, operational misconfigurations, and systemic fragility. This dissertation presents an empirical, measurement-driven …

Resolution in Internet Identifiers: Towards Context-Awareness and Customisation
Identity systems are the key to any network. Just as a language is defined by a consistent set of symbols and their usage, a network is defined by a consistent set of identities and their usage. For users to find this network useful, they must be able to communicate references using human-friendly …

Enhancing DNS data exfiltration protection through SDN data plane programming
… data breaches being reported annually [1]. The Domain Name System (DNS) protocol has been a popular choice for malicious communication channels for many years; the vulnerability was first publicly discussed in 1998. Now, many years on, this vulnerability remains and exploits against it have …

An investigation of mechanisms to mitigate zero-day computer worms within computer networks
… itself by automatically infecting vulnerable systems and may infect hundreds of thousands of hosts across the Internet in tens of minutes. The speed of propagation of a worm is significantly higher than many other types of malware, including viruses. The potential for signification damage …

A High-Availability Architecture for the Dynamic Domain Name System
The Domain Name System (DNS) provides a mapping between host names and Internet Protocol (IP) addresses. Hosts that are configured using the Dynamic Host Configuration Protocol (DHCP) can have their assigned IP addresses updated in a Dynamic DNS (DDNS). DNS and DDNS are critical components of the …

Monitoring security of enterprise hosts via DNS data analysis
… virtually all connected assets use the Domain Name System (DNS) for address resolution. Thus DNS has become a convenient vehicle for attackers to covertly perform Command and Control (C&C) communication, data theft, and service disruption across a wide range of assets. Enterprise …
