New Threats, New Approaches in Modern Data Centers - A Presentation by NPS at CENIC conference 11:00 am - 12:00 pm, Wednesday, March 22, 2017 – in San Diego, California
The standard approach to securing data centers has historically emphasized strong perimeter protection to keep threats on the outside of the network. However, this model is ineffective for handling new types of threats—including advanced persistent threats, insider threats, and coordinated attacks. A better model for data center security is needed: one that assumes threats can be anywhere and probably are everywhere and then, through automation, acts accordingly. Using micro-segmentation, fine-grained network controls enable unit-level trust, and flexible security policies can be applied all the way down to a network interface. In this joint presentation between customer, partner, and VMware, the fundamental tenants of micro-segmentation will be discussed. Presenters will describe how the Naval Postgraduate School has incorporated these principles into the architecture and design of a multi-tenant Cybersecurity Lab environment to deliver security training to national and international government personnel.

Carrier Grade Requirements for Cloud Computing: A SCOPE Alliance Perspective ...OpenSAF Foundation
The mission of Scope Alliance is to advance the objective of a vibrant and diverse ecosystem of COTS (commercial off-the-shelf): carrier-grade platform components utilizing open standards. Cloud Computing has the common goal of reducing the platform costs while continuing the direction of increased openness of the architecture.
Cloud providers have succeeded in pushing the cost of computation and storage down by concentration, virtualization and economies of scale; by doing so, they had to compromise on some fundamental issues, such as networking, security and real-time characteristics. In this session, we will define the differentiating factors that can enable the usability of cloud computing for telecom and real-time services. In this context, we will include the role and importance of inter-cloud architectures as well as the usage of private, public and hybrid architectures for real-time and telecom services. These aspects form the technical foundation for standardization efforts in the area of cloud computing, as well as the work agenda for the SCOPE Alliance in its relationship with various standardization bodies.

Edge device multi-unicasting for video streamingTal Lavian Ph.D.
After a decade of research and development, IP multicast has still not been deployed widely in the global Internet due to many open technical issues: lack of admission control, poorly scaled with large number of groups, and requiring substantial infrastructure modifications. To provide the benefits of IP multicast without requiring direct router support or the presence of a physical broadcast medium, various Application Level Multicast (ALM) models have been attempted. However, there are still several problems with ALM: unnecessary coupling between an application and its multicasting supports, bottleneck problem at network access links and considerable processing power required at the end nodes to support ALM mechanisms. This paper proposes an architecture to address these problems by delegating application-multicasting support mechanisms to smart edge devices associated with the application end nodes. The architecture gives rise to an interesting Edge Device Any-casting technology that lies between the IP-multicasting and the Application Layer Multicasting and enjoys the benefits of both. Furthermore, the architecture may provide sufficient cost-benefit for adoption by service providers. The paper presents initial results obtained from the implementation of a video streaming application over the testbed that implements the proposed architecture.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
