The subcommittee met, pursuant to call, at 2:06 p.m., in Room 311, Cannon House Office Building, Hon. John Ratcliffe [Chairman of the subcommittee] presiding. Present: Representatives Ratcliffe, McCaul, Marino, Donovan, Richmond, and Jackson Lee. Mr. RATCLIFFE. Good afternoon. The Committee on Homeland Se- curity Subcommittee on Cybersecurity, Infrastructure Protection, and Security Technologies will come to order. The subcommittee is meeting today to examine the evolving cy- bersecurity threats from nation-states such as China, Russia, North Korea, and Iran, as well as cyber threats from criminal orga- nizations and terrorist groups such as ISIS. Over the last several years, we have seen these actors continue to develop and build even more sophisticated cyber capabilities. In 2016, these hackers pose an even greater threat to the U.S. home- land and our critical infrastructure. To put it simply, cybersecurity is National security. In 2015, the Nation was victim to one of the most significant cyber attacks in our history. The breach at the Office of Personnel Management exposed the personal and extremely sensitive security clearance information of 21.5 million current and former Govern- ment employees. In 2014, we saw North Korea conduct a cyber at- tack on Sony Pictures that not only destroyed computers, but also sought to muzzle free speech and threaten American ideals. Unfortunately, the administration’s lack of proportional re- sponses to these cyber attacks has demonstrated to the world that there are no real consequences for such actions. Without a com- prehensive National cybersecurity strategy that addresses deter- rence effectively, I worry that 20l6 could bring an increasing num- ber of those willing to push the boundaries. In recent news, a lot of attention was directed at the Hollywood Presbyterian Medical Center in Los Angeles that was a victim of a ransomware attack. This type of malware infects victims’ com- puters and locks them until a payment, or a ‘‘ransom,’’ is made. The medical center was forced to pay $17,000 to restore its sys- tems. (1) 2 But this isn’t a problem unique to Hollywood. In my own district in Northeast Texas, the Titus Regional Medical Center suffered a similar attack. Their electronic health record system was locked, and they weren’t able to access patient information. Of the nation states, Russia continues to rank near the top in terms of capabilities, with increasing aggression across the globe that may continue to manifest itself in cyber space. The director of national intelligence, James Clapper, told the Senate Armed Serv- ices Committee in September that the Russian government is es- tablishing its own central cyber command that will be responsible for carrying out offensive cyber operations. China also ranks high in terms of capability, and it continues to pose a significant threat to the United States in terms of cyber es- pionage and the theft of intellectual property. In September, the administration announced an agreement with the Chinese govern- ment to refrain from engaging in hacking of our intellectual prop- erty. I look forward to hearing today from our industry witnesses on their thoughts about the success of this agreement. Iran continues to emerge as a top cybersecurity threat, as well. While many would argue that its intent to carry out its attacks is

  • Bitcoin 2: Freedom of Transaction
    Bitcoin 2: Freedom of Transaction Sid Angeles and Eric Gonzalez [email protected] AF76 05E5 EB15 2B00 AB18 204C 11C9 1C8B EA6C 7389 [email protected] 3A85 7ABC 9453 96E4 B9DB 2A11 7370 E15E 8F60 2788 Donations: 1btctwojvohHSLaXaJAHWebZF2RS8n1NB Revision 2 July 23, 2013 Abstract We propose a set of changes to the original Bitcoin protocol (called Bitcoin 2) that allows Bitcoin to evolve into a system that is future-proof against developing threats to its original vision – an alternative, decentralized payment system which allows censorship-resistant, irreversible transac- tions. Bitcoin 2 strives to be a minimal set that lays the foundations for a long-lived system capable of delivering the original Bitcoin vision, with enough room for growth to layer additional im- provements on top of it. These changes include a sliding blockchain with fixed block sizes, the redistribution of dead coins with an unforgeable lottery, enforced mixing, and miner ostracism. The proposed changes require a proactive fork of the original Bitcoin block chain, but they allow final transfers of existing coins into Bitcoin 2 and a reuse of the existing Bitcoin infrastruc- ture. 1 Introduction The Bitcoin peer-to-peer electronic cash system [11] was introduced in 2009 and it proved to be a remarkable piece of work which found widespread adoption. The system was started with the explicit goal of providing a completely alternative payment system without a single point of failure that allows anonymous, but not untraceable, transactions. However, certain shortcomings in the original protocol and unforeseen developments inside and outside of the growing Bitcoin ecosystem threaten these very goals and there is good reason to believe that Bitcoin could develop into a system that is a complete perversion of the original vision – a com- pletely transparent payment system with very few points of control which has been totally absorbed by the established financial and regulatory environment.

  • Terabyte Sneakernet: the Carry-On Data Center by Drew Hamre
    December 2007 Terabyte SneakerNet: The Carry-on Data Center By Drew Hamre I recently helped relocate a data center for a US government agency, moving system images from Virginia to a consolidated facility in Minnesota. During ‘cutover’ weekend, production systems in Virginia were dropped and remained unavailable until data could be refreshed at the Minnesota data center and the new systems could be brought online. To minimize downtime, the time allotted for refreshing data across locations was extremely brief. email This data transfer was daunting for two reasons: the amount of data being moved was large (as much as two-terabytes would be moved during cutover weekend), and the network between the two sites was slow. Portable media were the only viable alternative, but these devices would need to meet extremely difficult requirements. They would need to be fast (due to the brief transfer window), inexpensive (no hardware funds were budgeted) and portable (devices needed to be hand-carried by agents to meet security mandates). Ideally, the team needed to find fast, cheap transfer devices that could be stowed in an airliner’s overhead bin. This paper reviews alternatives for the transfer, focusing on the latest generation of commodity Network Attached Storage (NAS) devices that allowed agents to transfer as much as 12-terabytes in a single carry-on duffle bag. Background: Transitioning Data Centers At the time of the transition, both data centers were fully functional: Virginia supported production, while Minnesota (a parallel environment running pre-staged system images on new hardware) supported acceptance testing. Minnesota’s parallel environment included a full snapshot of Virginia’s file system and databases (roughly 10-terabytes in total).

Diss., Technische Universität Carolo Wilhelmina zu Braunschweig, 2015 © 2015 Johannes Morgenroth Herstellung: BoD – Books on Demand, Norderstedt BoD Ref. 0011632925 Abstract Continuous end-to-end connectivity is not available all the time, not even in wired networks. Thus, the »Off-line first« paradigm is applied to applications of mobile devices to deal with intermittent connectivity without annoying the users every time the network is going to be flaky. But since mobile devices, particularly smart- phones, are typically bound to the Internet, they become almost useless as soon as their connectivity is gone. Delay- and Disruption-Tolerant Networking (DTN) al- lows devices to communicate even if there is no continuous path to the destination by replacing the end-to-end semantics with a hop-by-hop store-carry-and-forward approach. Since existing implementations of DTN software suffer from various limita- tions, this thesis presents an event-driven software architecture for Delay- and Disruption-Tolerant Networking and a lean, lightweight, and extensible imple- mentation of a bundle node.

  • The Darknet and the Future of Content Distribution
    The Darknet and the Future of Content Distribution Peter Biddle, Paul England, Marcus Peinado, and Bryan Willman Microsoft Corporation1 Abstract We investigate the darknet – a collection of networks and technologies used to share digital content. The darknet is not a separate physical network but an application and protocol layer riding on existing networks. Examples of darknets are peer-to-peer file sharing, CD and DVD copying, and key or password sharing on email and newsgroups. The last few years have seen vast increases in the darknet’s aggregate bandwidth, reliability, usability, size of shared library, and availability of search engines. In this paper we categorize and analyze existing and future darknets, from both the technical and legal perspectives. We speculate that there will be short-term impediments to the effectiveness of the darknet as a distribution mechanism, but ultimately the darknet-genie will not be put back into the bottle. In view of this hypothesis, we examine the relevance of content protection and content distribution architectures. 1 Introduction People have always copied things. In the past, most items of value were physical objects. Patent law and economies of scale meant that small scale copying of physical objects was usually uneconomic, and large-scale copying (if it infringed) was stoppable using policemen and courts. Today, things of value are increasingly less tangible: often they are just bits and bytes or can be accurately represented as bits and bytes. The widespread deployment of packet-switched networks and the huge advances in computers and codec-technologies has made it feasible (and indeed attractive) to deliver such digital works over the Internet.
