Distributed Denial of Service (DDoS) attacks continue to present a clear and imminent danger to critical network infrastructures. DDoS attacks have increased in sophistication with advanced strategies to continuously adapt (e.g., changing threat postures dynamically) and induce collateral damage (i.e., higher latency and loss for legitimate traffic). Furthermore, advanced attacks may also employ reconnaissance (e.g., mapping the network to find bottleneck links) to target the network infrastructure itself. In light of these trends, state-of-art defenses (e.g., advanced scrubbing, emerging software-defined defenses, and programmable switching hardware) have fundamental shortcomings. This project will develop a new framework, referred to as "Optics-enabled In-Network defenSe for Extreme Terabit DDoS attacks" (ONSET). The framework makes a case for new dimensions of defense agility that can programmatically control the topology of the network (in addition to the processing behavior) to tackle advanced and future attacks. The project will facilitate the use of optical technologies as an exciting visual medium for engaging K-12 students via suitable channels for dissemination. The project will also result in new course materials at the intersection of optical networking, software-defined networking, and network security to enable students to become domain experts in this emerging problem space. The project will take an interdisciplinary approach spanning security, optics, systems, and networks, to address fundamental challenges along three thrusts: (1) novel "data plane" solutions to rapidly reconfigure the wavelengths and switches and new capabilities in programmable switches to rapidly identify malicious vs. benign traffic at line rate; (2) novel "control plane" orchestration mechanisms for scalable resource management algorithms and coordinated control across optical networking and programmable switches; and (3) new "northbound application programming interfaces (APIs)" to express novel defenses to combat current and future DDoS attacks (e.g., with reconnaissance). This project will develop a new framework, referred to as "Optics-enabled In-Network defenSe for Extreme Terabit DDoS attacks" (ONSET). The research efforts will result in end-to-end prototypes using open-source and standardized interfaces to demonstrate the novel defense capabilities of ONSET. The efficacy of ONSET will be evaluated using pilot studies on operational networks to create a roadmap to practical deployment, using real testbeds and large-scale simulations. The project outcomes will be released as open-source software tools, models, and simulation frameworks that will inform industry and academic work.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

分布式拒绝服务 (DDoS) 攻击继续对关键网络基础设施构成明显且迫在眉睫的危险。 DDoS 攻击的复杂性不断提高，采用了先进的策略来不断适应（例如，动态改变威胁态势）并引发附带损害（即合法流量的延迟和丢失更高）。此外，高级攻击还可能采用侦察（例如，映射网络以查找瓶颈链接）来瞄准网络基础设施本身。鉴于这些趋势，最先进的防御（例如高级清理、新兴的软件定义防御和可编程交换硬件）具有根本性的缺点。该项目将开发一个新框架，称为“针对极端太比特 DDoS 攻击的光学网络内防御”(ONSET)。该框架为防御敏捷性的新维度提供了案例，可以以编程方式控制网络拓扑（除了处理行为之外）以应对高级和未来的攻击。该项目将促进光学技术作为令人兴奋的视觉媒介的使用，通过适当的传播渠道吸引 K-12 学生。该项目还将推出光网络、软件定义网络和网络安全交叉领域的新课程材料，使学生能够成为这个新兴问题领域的领域专家。该项目将采用涵盖安全、光学、系统和网络的跨学科方法，以解决三个方面的基本挑战：(1) 新颖的“数据平面”解决方案，可快速重新配置波长和交换机，以及可编程交​​换机的新功能，可快速识别线速下的恶意流量与良性流量； (2)新颖的“控制平面”编排机制，用于可扩展的资源管理算法以及跨光网络和可编程交换机的协调控制； (3) 新的“北向应用程序编程接口 (API)”，用于表达新颖的防御措施，以对抗当前和未来的 DDoS 攻击（例如，侦察）。该项目将开发一个新框架，称为“针对极端太比特 DDoS 攻击的光学网络内防御”(ONSET)。研究工作将产生使用开源和标准化接口的端到端原型，以展示 ONSET 的新颖防御能力。 ONSET 的功效将通过对运营网络的试点研究进行评估，以使用真实的测试平台和大规模模拟来创建实际部署的路线图。该项目成果将作为开源软件工具、模型和模拟框架发布，为行业和学术工作提供信息。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查进行评估，被认为值得支持标准。
