Our DSN’15 paper “FloodGuard: A DoS Attack Prevention Extension in Software-Defined Networks” (by Haopei Wang, Lei Xu, Guofei Gu) received the Test of Time Award at this year’s DSN conference (2025 Annual IEEE/IFIP International Conference on Dependable Systems and Networks)! We are so honored and humbled to receive this recognition for our SDN security research in 2015! Congratulations again, Haopei & Lei!

Some background information about this award: “The Test-of-Time Award recognizes two outstanding papers published 10 years ago at DSN, in the DSN proceedings (research track, practical experience report or tool papers), that have had a sustained and important impact on the theory and/or practice of dependable systems and networks computing research. DSN has several areas under its umbrella and with two awards there are conditions to recognize more than one area. In exceptional situations (not enough nominations), the time frame for awards can be extended to 10-12 years, and only one paper can be awarded, in this order.”

Our new paper on understanding the risks of dynamic content in the Alexa skill ecosystem is going to appear in ACM WiSec’25! Congratulations, Nathan!

Shreyas has two papers on human-centered security research to appear in Euro S&P’25! They are “Demystifying the Perceptions Gap Between Designers and Practitioners in Two Security Standards” and “Incentivizing Security Excellence in Cyber Liability Insurance”. Congratulations, Shreyas!

Our paper “Beyond Visual Confusion: Understanding How Inconsistencies in ENS Normalization Facilitate Homoglyph Attacks” is accepted to WWW’25. Congratulations, Jianwei!

Recently, automatic moving target defense (AMTD) is recognized as a promising proactive defense technique against cyber attacks. In particular, NTO (Network Topology Obfuscation) is an emerging AMTD approach for dynamic reconfiguration of network infrastructure/configuration. In our new research that will appear in USENIX Security’24, we introduce a new CrossPoint attack that can escape the security protections of state-of-the-art NTO defenses. Congratulations, Xuanbo!

Our paper “WIRE: Web3 Integrated Reputation Engine” is accepted to ICDCS’24. Inspired by the FICO score system in traditional finance, we introduce WIRE, a new reputation engine designed to evaluate the trustworthiness of deployed DApps in the Web3 (blockchain/cryptocurrency/etc.) world! We’re releasing our prototype here! Congratulations to Suraj & Huancheng!

Our ACSAC’07 paper “A Taxonomy of Botnet Structures” (by David Dagon, Guofei Gu, Christopher P. Lee, and Wenke Lee) received the Test of Time Paper Award at this year’s ACSAC conference (2023)! We are so honored and humbled to receive this recognition for our botnet research in 2007!

Some background on the award from ACSAC: “These awards provide an opportunity to honor papers that have been published at ACSAC that have had enduring significance and impact to the security community. The committee considered papers published more than 15 years ago, and discussed their impact on academia, industry, and government. “

Our new research work “Mew” in the area of SPS (Software-defined Programmable Security) is accepted by IEEE S&P. This work shows how we can enable large-scale and dynamic link-flooding defenses on programmable switches. Congratulations, Huancheng!
