Shared Resource Matrix Methodology: an Approach to Identifying Storage and Timing Channels
Shared Resource Matrix Methodology: An Approach to Identifying Storage and Timing Channels RICHARD A. KEMMERER University of California, Santa Barbara Recognizing and dealing with storage and timing channels when performing the security analysis of a computer system is an elusive task. Methods for discovering and dealing with these channels have mostly been informal, and formal methods have been restricted to a particular specification language. A methodology for discovering storage and timing channels that can be used through all phases of the software life cycle to increase confidence that all channels have been identified is presented. The methodology is presented and applied to an example system having three different descriptions: English, formal specification, and high-order language implementation. Categories and Subject Descriptors: C.2.0 [Computer-Communication Networks]: General--se- curity and protection; D.4.6 ]Operating Systems]: Security and Protection--information flow controls General Terms: Security Additional Key Words and Phrases: Protection, confinement, flow analysis, covert channels, storage channels, timing channels, validation 1. INTRODUCTION When performing a security analysis of a system, both overt and covert channels of the system must be considered. Overt channels use the system's protected data objects to transfer information. That is, one subject writes into a data object and another subject reads from the object. Subjects in this context are not only active users, but are also processes and procedures acting on behalf of the user. The channels, such as buffers, files, and I/O devices, are overt because the entity used to hold the information is a data object; that is, it is an object that is normally viewed as a data container. -
Shared Resource
Shared resource In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network.[1][2] It is a device or piece of information on a computer that can be remotely accessed from another computer transparently as if it were a resource in the local machine. Network sharing is made possible by inter-process communication over the network.[2][3] Some examples of shareable resources are computer programs, data, storage devices, and printers. E.g. shared file access (also known as disk sharing and folder sharing), shared printer access, shared scanner access, etc. The shared resource is called a shared disk, shared folder or shared document The term file sharing traditionally means shared file access, especially in the context of operating systems and LAN and Intranet services, for example in Microsoft Windows documentation.[4] Though, as BitTorrent and similar applications became available in the early 2000s, the term file sharing increasingly has become associated with peer-to-peer file sharing over the Internet. Contents Common file systems and protocols Naming convention and mapping Security issues Workgroup topology or centralized server Comparison to file transfer Comparison to file synchronization See also References Common file systems and protocols Shared file and printer access require an operating system on the client that supports access to resources on a server, an operating system on the server that supports access to its resources from a client, and an application layer (in the four or five layer TCP/IP reference model) file sharing protocol and transport layer protocol to provide that shared access. -
A Letter to the FCC [PDF]
Before the FEDERAL COMMUNICATIONS COMMISSION Washington, DC 20554 In the Matter of ) ) Amendment of Part 0, 1, 2, 15 and 18 of the ) ET Docket No. 15170 Commission’s Rules regarding Authorization ) Of Radio frequency Equipment ) ) Request for the Allowance of Optional ) RM11673 Electronic Labeling for Wireless Devices ) Summary The rules laid out in ET Docket No. 15170 should not go into effect as written. They would cause more harm than good and risk a significant overreach of the Commission’s authority. Specifically, the rules would limit the ability to upgrade or replace firmware in commercial, offtheshelf home or smallbusiness routers. This would damage the compliance, security, reliability and functionality of home and business networks. It would also restrict innovation and research into new networking technologies. We present an alternate proposal that better meets the goals of the FCC, not only ensuring the desired operation of the RF portion of a WiFi router within the mandated parameters, but also assisting in the FCC’s broader goals of increasing consumer choice, fostering competition, protecting infrastructure, and increasing resiliency to communication disruptions. If the Commission does not intend to prohibit the upgrade or replacement of firmware in WiFi devices, the undersigned would welcome a clear statement of that intent. Introduction We recommend the FCC pursue an alternative path to ensuring Radio Frequency (RF) compliance from WiFi equipment. We understand there are significant concerns regarding existing users of the WiFi spectrum, and a desire to avoid uncontrolled change. However, we most strenuously advise against prohibiting changes to firmware of devices containing radio components, and furthermore advise against allowing nonupdatable devices into the field. -

Resource Management in Multimedia Networked Systems Abstract Error-free multimedia data processing and communication includes providing guaranteed services such as the colloquial telephone. A set of problems have to be solved and handled in the control-management level of the host and underlying network architectures. We discuss in this paper 'resource management' at the host and network level, and their cooperation to achieve global guaranteed transmission and presentation services, which means end-to-end guarantees. The emphasize is on 'network resources' (e.g., bandwidth, buffer space) and 'host resources' (e.g., CPU processing time) which need to be controlled in order to satisfy the Quality of Service (QoS) requirements set by the users of the multimedia networked system. The control of the specified esourr ces involves three actions: (1) properly allocate resources (end-to-end) during the multimedia call establishment, so that traffic can flow according to the QoS specification; (2) control resource allocation during the multimedia transmission; (3) adapt to changes when degradation of system components occurs. -

The Internet and Isi: Four Decades of Innovation
THE INTERNET AND ISI: FOUR DECADES OF INNOVATION ROD BECKSTROM President and Chief Executive Officer Internet Corporation for Assigned Names and Numbers (ICANN) 40th Anniversary of USC Information Sciences Institute 26 April 2012 As prepared for delivery It’s an honor to be here today to mark the 40th anniversary of the University of Southern California’s Information Sciences Institute. Thank you to Herb Schorr for inviting me to speak with you today and participate in the day’s events. When he steps down he will leave some very large shoes to fill. When I received Herb’s invitation, I seized upon it as an opportunity to come before you to express the sincere gratitude that my colleagues and I feel for the work and support of ISI. When I think of ICANN and its development, and all we have accomplished, I never forget that we stand upon the shoulders of giants, many of whom contributed to my remarks today. In fact, I owe a special debt of gratitude to Bob Kahn, who has been a mentor to me. I am honored that he took the time to walk through a number of details in the history I have been asked to relate. The organizers asked me to speak about the history of ISI and ICANN. They also invited me to talk a bit about the future of the Internet. In my role as President and CEO of ICANN, I have many speaking engagements that are forward looking. They are opportunities to talk about ICANN’s work and how it will usher in the next phase in the history of the global, unified Internet that many of you have helped to create. -
Site Finder and Internet Governance
345 Site Finder and Internet Governance Jonathan Weinberg* 347 INTRODUCTION 348 PART 1. 354 PART 2. 361 PART 3. 366 PART 4. 375 CONCLUSION Copyright © 2004 by Jonathan Weinberg. * Professor of Law, Wayne State University. I am grateful to Michael Froomkin, Mark Lemley, David Maher, Milton Mueller, and Jessica Litman for their comments, and to Susan Crawford and Bret Fausett for answer- ing questions along the way. None of them, of course, is responsible for anything I say here. This essay reflects developments taking place through 30 November 2003. 347 Site Finder and Internet Governance Jonathan Weinberg INTRODUCTION ON SEPTEMBER 15, 2003, VeriSign, Inc.—the company that operates the data- bases that allow internet users to reach any internet resource ending in “.com” or “.net”—introduced a new service it called Site Finder. Less than three weeks later, after widespread protest from the technical community, at least three law- suits, and a stern demand from ICANN (the Internet Corporation for Assigned Names and Numbers, which has undertaken responsibility for managing the internet domain name space), VeriSign agreed to shut Site Finder down.1 In between those dates the internet community saw a passionate debate over the roles of ICANN, VeriSign, and the internet’s technical aristocracy in managing the domain name space. VeriSign has charged that its opponents’ reactions were the product of “obsolete thinking” that would disable it from “build[ing] a commercial busi- ness.”2 ICANN, for its part, is seeking to enact a procedure under which top-level domain name registry operators such as VeriSign must seek ICANN’s approval before offering new services or taking any “significant actions that...could affect the operational stability, reliability, security or global interoperability of...the Internet.”3 Some see fault on all sides: “It’s hard to say,” writes one commenta- tor, “in this case who is being more anti-competitive, ICANN or VeriSign.”4 In this essay, I will try to unpack the Site Finder story. -
To the Members of the Senate Judiciary Committee: We, The
To the members of the Senate Judiciary Committee: We, the undersigned, have played various parts in building a network called the Internet. We wrote and debugged the software; we defined the standards and protocols that talk over that network. Many of us invented parts of it. We're just a little proud of the social and economic benefits that our project, the Internet, has brought with it. We are writing to oppose the Committee's proposed new Internet censorship and copyright bill. If enacted, this legislation will risk fragmenting the Internet's global domain name system (DNS ), create an environment of tremendous fear and uncertainty for technological innovation, and seriously harm the credibility of the United States in its role as a steward of key Internet infrastructure. In exchange for this, the bill will introduce censorship that will simultaneously be circumvented by deliberate infringers while hampering innocent parties' ability to communicate. All censorship schemes impact speech beyond the category they were intended to restrict, but this bill will be particularly egregious in that regard because it causes entire domains to vanish from the Web, not just infringing pages or files. Worse, an incredible range of useful, law-abiding sites can be blacklisted under this bill. These problems will be enough to ensure that alternative name-lookup infrastructures will come into widespread use, outside the control of US service providers but easily used by American citizens. Errors and divergences will appear between these new services and the current global DNS, and contradictory addresses will confuse browsers and frustrate the people using them. -

We rely on the Internet as an essential tool for our economic, social, educational, and political lives. But when the Internet Engineering Task Force meets every four months at an open conference that bounces from continent to continent, more than 1,000 people from around the world gather with change on their minds. Their vision of the global network that all humanity shares is dynamic, evolving, and continuously improving. Their efforts combine with the contributions of myriad others to ensure that the Internet always works but is never done, never complete. The rapid yet orderly evolution of the Internet is all the more remarkable considering the highly unusual way it happens: without a company, a government, or a board of directors in charge. Nothing about digital communications technology suggests that it should be self-organizing or, for that matter, fundamentally reliable.

July 18, 2012 Chairman Julius Genachowski Federal Communications Commission 445 12th Street SW Washington, DC 20554 Re: Letter, CG Docket No. 09-158, CC Docket No. 98-170, WC Docket No. 04-36 Dear Chairman Genachowski, Open data and an independent, transparent measurement framework must be the cornerstones of any scientifically credible broadband Internet access measurement program. The undersigned members of the academic and research communities therefore respectfully ask the Commission to remain committed to the principles of openness and transparency and to allow the scientific process to serve as the foundation of the broadband measurement program. Measuring network performance is complex. Even among those of us who focus on this topic as our life’s work, there are disagreements. The scientific process happens best in the sunlight and that can only happen when as many eyes as possible are able to look at a shared set of data, work to replicate results, and assess its meaning and impact. This ensures the conclusions from the broadband measurement allow for meaningful, data-driven policy making. Since the inception of the broadband measurement program, those of us who work on Internet research have lauded its precedent-setting commitment to open-data and transparency. Many of us have engaged with this program, advising on network transparency and measurement methodology and using the openly-released raw data as a part of our research. However, we understand that some participants in the program have proposed significant changes that would transform an open measurement process into a closed one. Specifically, that the Federal Communications Commission (FCC) is considering a proposal to replace the Measurement Lab server infrastructure with closed infrastructure, run by the participating Internet service providers (ISPs) whose own speeds are being measured.
