II-New: Enabling Security Analysis at Scale

该项目将通过基础设施拨款提供计算设备，这将增强对网络空间中经验性社会和经济现象的分析能力，例如，大规模在线社交网络、恶意网络内容和地下网络犯罪市场。像Facebook和Twitter这样的流行在线网站连接了数十亿人；然而，在网络犯罪的推动下，这些网站面临着全新的威胁。在缺乏有效防御的情况下，今天的在线社交生态系统受到了影响。在当今庞大的网络基础设施中，对这些威胁和缓解策略的实证研究需要高度可扩展和功能强大的网络基础设施。通过这项设备拨款，更好地了解这些复杂的网络生态系统将为使网络空间更安全带来新的见解。

This project will provide the computing equipment through an infrastructure grant that will enable greater capability for analysis of empirical social and economic phenomena, mediated in cyberspace such as, for example, massive online social networks, malicious web content, and underground cybercrime markets. The popular online sites like Facebook and Twitter connect literally billions of people; however, entirely new threats to such sites have emerged driven by cybercrime. In the absence of effective defenses, online social ecosystems today suffer. The empirical study of these threats and mitigating strategies in today's enormous web infrastructure requires a highly scalable and capable cyber infrastructure. Better understanding these complex cyber ecosystems, made possible through this equipment grant, will lead to new insights for making cyberspace safer.
