Access Control
Security Engineering: A Guide to Building Dependable Distributed Systems CHAPTER 4 Access Control Going all the way back to early time-sharing systems, we systems people regarded the users, and any code they wrote, as the mortal enemies of us and each other. We were like the police force in a violent slum. —ROGER NEEDHAM Microsoft could have incorporated effective security measures as standard, but good sense prevailed. Security systems have a nasty habit of backfiring, and there is no doubt they would cause enormous problems. —RICK MAYBURY 4.1 Introduction Access control is the traditional center of gravity of computer security. It is where se- curity engineering meets computer science. Its function is to control which principals (persons, processes, machines, . .) have access to which resources in the sys- tem—which files they can read, which programs they can execute, how they share data with other principals, and so on. NOTE This chapter necessarily assumes more computer science background than previous chapters, but I try to keep it to a minimum. 51 Chapter 4: Access Controls Figure 4.1 Access controls at different levels in a system. Access control works at a number of levels, as shown in Figure 4.1, and described in the following: 1. The access control mechanisms, which the user sees at the application level, may express a very rich and complex security policy. A modern online busi- ness could assign staff to one of dozens of different roles, each of which could initiate some subset of several hundred possible transactions in the system. Some of these (such as credit card transactions with customers) might require online authorization from a third party while others (such as refunds) might require dual control. -

INTRODUCTION ¶1 This paper focuses on the subsidization of a technology-based durable good.1 It goes on to discuss the delicate dance between the producer trying to protect its profit, competitors trying to create and sell aftermarket goods,2 and those innovative customers who use the items in completely unplanned and unprofitable ways. ¶2 An age old, but increasingly popular business model involves the subsidization of a proprietary durable good by a manufacturer, such that the good is sold below cost.3 Due to careful design, technological, and legal restrictions, the producer creates a primary product that is only compatible with its own aftermarket goods. -
The Basic Economics of Internet Infrastructure
Journal of Economic Perspectives—Volume 34, Number 2—Spring 2020—Pages 192–214 The Basic Economics of Internet Infrastructure Shane Greenstein his internet barely existed in a commercial sense 25 years ago. In the mid- 1990s, when the data packets travelled to users over dial-up, the main internet T traffic consisted of email, file transfer, and a few web applications. For such content, users typically could tolerate delays. Of course, the internet today is a vast and interconnected system of software applications and computing devices, which society uses to exchange information and services to support business, shopping, and leisure. Not only does data traffic for streaming, video, and gaming applications comprise the majority of traffic for internet service providers and reach users primarily through broadband lines, but typically those users would not tolerate delays in these applica- tions (for usage statistics, see Nevo, Turner, and Williams 2016; McManus et al. 2018; Huston 2017). In recent years, the rise of smartphones and Wi-Fi access has supported growth of an enormous range of new businesses in the “sharing economy” (like, Uber, Lyft, and Airbnb), in mobile information services (like, social media, ticketing, and messaging), and in many other applications. More than 80 percent of US households own at least one smartphone, rising from virtually zero in 2007 (available at the Pew Research Center 2019 Mobile Fact Sheet). More than 86 percent of homes with access to broadband internet employ some form of Wi-Fi for accessing applications (Internet and Television Association 2018). It seems likely that standard procedures for GDP accounting underestimate the output of the internet, including the output affiliated with “free” goods and the restructuring of economic activity wrought by changes in the composition of firms who use advertising (for discussion, see Nakamura, Samuels, and Soloveichik ■ Shane Greenstein is the Martin Marshall Professor of Business Administration, Harvard Business School, Boston, Massachusetts. -

Sega Was Important in the IP-In-Interfaces Odyssey for at Least
Draft as of August 21, 2008 Please do not cite, copy, or distribute without the author’s permission. Are Patents on Interfaces Impeding Interoperability? by Pamela Samuelson* Abstract: Many patents have issued for communications protocols and other interface designs for information and communications technologies (ICT). Commentators and policymakers have frequently expressed concern about the exclusionary potency of interface patents because they can confer on patentees power to block interoperability in socially harmful ways. This Article considers numerous policy options that have been proposed to respond to the dangers posed by interface patents, including exclusions of interfaces from patent protection, immunization of use of patented interfaces if necessary to achieve interoperability, withholding injunctive relief for infringement of interface patents, and treating refusals to license interface patents as abuses of intellectual property rights or violations of competition or antitrust laws. The Article observes that a great deal of interoperability is occurring notwithstanding the existence of interface patents, in part because private consortia have adopted policies in support of interoperability and in part because owners of such patents often have incentives to license them to facilitate interoperability. There is as yet insufficient evidence that interface patents are such serious impediments to interoperability as to justify adoption of strong measures, such as their exclusion from patent protection. INTRODUCTION Interoperability among information and communications technologies (ICT) is widely praised for promoting socially desirable goals, including fostering competition and innovation, enhancing consumer satisfaction, and promoting economic growth.1 ICT interoperability means “the ability to transfer and render useful data and other information across systems, applications, or components.”2 To achieve interoperability, firms must have access to and be able to use the precise information that defines the * Richard M.
