We propose that to address the growing problems with complexity and data volumes in HPC security wee need to refactor how we look at data by creating tools that not only select data, but analyze and represent it in a manner well suited for intuitive analysis. We propose a set of rules describing what this means, and provide a number of production quality tools that represent our current best effort in implementing these ideas.

The finalization of the 100 Gbps Ethernet Specification has been a tremendous increase in these rates arriving into data centers creating the need to perform security monitoring at 100 Gbps no longer simply an academic exercise. We show that by leveraging the ‘heavy tail flow effect’ on the IDS infrastructure, it is possible to perform security analysis at such speeds within the HPC environment. Additionally, we examine the nature of current traffic characteristics, how to scale an IDS infrastructure to 100Gbps.

Driven by the growing data transfer needs of the scientific community and the standardization of the 100 Gbps Ethernet Specification, 100 Gbps is now becoming a reality for many HPC sites. This tenfold increase in bandwidth creates a number of significant technical challenges. We show that by using the heavy tail flow effect as a filter, it should be possible to perform active IDS analysis at this traffic rate using a cluster of commodity systems driven by a dedicated load balancing mechanism. Additionally, we examine the nature of current network traffic characteristics applying them to 100Gpbs speeds

Fast Flux Service Networks (FFSN) utilize high availability server techniques for malware distribution. FFSNs are similar to commercial content distribution networks (CDN), such as Akamai, in terms of size, scope, and business model, serving as an outsourced content delivery service for clients. Using an analysis of DNS traffic, we derive a sequential hypothesis testing algorithm based entirely on traffic characteristics and dynamic white listing to provide real time detection of FFDNs in live traffic. We improve on existing work, providing faster and more accurate detection of FFSNs. We also identify a category of hosts not addressed in previous detectors - Open Content Distribution Networks (OCDN) that share many of the characteristics of FFSNs

At the request of the U.S. Department of Energy’s (DOE) Advanced Scientific Computing Research (ASCR) program, a workshop was held January 7–9, 2015, in Rockville, Md., to examine computer security research gaps and approaches for assuring scientific computing integrity specific to the mission of the DOE Office of Science. Issues included research computation and simulation that takes place on ASCR computing facilities and networks, as well as network-connected scientific instruments, such as those run by other DOE Office of Science programs. Workshop participants included researchers and operational staff from DOE national laboratories, as well as academic researchers and industry experts. Participants were selected based on the prior submission of abstracts relating to the topic. Additional input came from previous DOE workshop reports [DOE08,BB09] relating to security. Several observers from DOE and the National Science Foundation also attended.

Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. Considering the extreme scale of contemporary datasets, one significant challenge is to reduce the duty cycle in the analytics discourse process. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysistechnologies targeted at reducing the duty cycle in hypothesis testing and knowledge discovery. We present an application of such a combination in the problem domain of network traffic dataanalysis. Our performance experiment results, including both serial and parallel scalability tests, show that the combination can dramatically decrease the analytics duty cycle for this particular application. The combination is effectively applied to the analysis of network traffic data to detect slow and distributed scans, which is a difficult-to-detect form of cyberattack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools
