Proving Voltaire Right: Security Blunders Dumber Than Dog Snot

Roger G. Johnston, Vulnerability Assessment Team, Argonne National Laboratory

View the video

Voltaire famously said (sort of) that the main problem with common sense is that it is not all that common. Security is certainly a case in point. As vulnerability assessors, we repeatedly encounter security devices, systems, and programs with little or no security (or security thought) built in. We witness well-designed security products used stupidly, ill-conceived security rules that make security worse, organizations with security cultures beyond pathological, and security programs heavily mired in Security Theater, groupthink, bureaucracy, and wishful thinking.

This talk gives examples of common design blunders, easy-to-exploit vulnerabilities, poor usage, and sloppy thinking associated with various electronic devices involving physical security, including locks, tags, tamper-indicating seals, GPS, RFIDs, biometrics and other access control devices, and electronic voting machines. Common blunders in how organizations think about security and how they deal with the Insider Threat, IT vulnerabilities, and vulnerability assessments will also be discussed.

I'll conclude by proposing some reasons why common sense and security are so often alien to each other and suggest possible countermeasures—some of which involve examining what cyber security and physical security could learn from each other.

Toward an Open and Secure Platform for Using the Web
Will Drewry, Software Security Engineer, Google

View the presentation slides

View the video

As users spend more of their computing time in the highly interconnected world of the Internet, their software and data are exposed to attackers at an increasing rate. Web browser developers are pursuing features to mitigate this exposure, but these mechanisms are primarily restricted to the browser itself. Google Chrome OS is an open source, lightweight operating system built for simplicity, speed, and security for Web-focused users. Its security functionality extends beyond the benefits of the browser, Google Chrome, to the core operating system environment. This talk will explore the design and implementation of that functionality and the challenges that lie ahead.

Windows 7 Security from a UNIX Perspective
Crispin Cowan, Senior Program Manager, Windows Core Security, Microsoft, Inc.

View the video

UNIX advocates, including me, have long mocked Windows for having a fundamentally insecure computing model. Issues have included the lack of separation of privilege between the user and the TCB, an over-eager willingness to execute code from untrusted sources, and a plethora of buffer overflow vulnerabilities. However, most of these criticisms pertain to Windows XP, a system that is now almost a decade old, or the even older Windows 9X series. Much has changed between Windows XP and Windows 7. This talk will compare and contrast the security of Windows and UNIX, at both technological and cultural levels, with results that may surprise members of both Windows and UNIX communities.

Docile No More: The Tussle to Redefine the Internet
James Lewis, Senior Fellow and Program Director at the Center for Strategic and International Studies

View the video

The Internet and its technologies were largely designed by Americans, and thus mirror the values and beliefs of these pioneers: open, non-hierarchical, non-governmental, and self-organizing. Other nations with different beliefs want to change this. They want a larger role for governments and an end to America's "technological hegemony." Their motives are commercial and political, and they reflect a general annoyance with a laissez-faire approach to governance that works against security and that foreign observers believe is just a plot to provide advantages to U.S. companies and "control" to the U.S. government. Other governments want to reshape the principles baked into the rules and technology of the Internet. This in itself is interesting, but it may be more interesting to ask—now that the age of Internet pioneers is over and change is inevitable—what values and beliefs will guide it.

The World Wide Web is rapidly evolving, and its corresponding security and privacy problems are changing, too. More than ever before, user agents such as Firefox are being relied upon to provide a safe browsing experience, and so we must adapt to the ever-changing state of the Web. Sid will recount some stories of security problems in Mozilla's past and will examine the current state of security and privacy in Firefox. Finally, he will describe the future of the Web browser, covering Mozilla's plans for upcoming releases and examining some questions in Web security and privacy that don't yet have answers.

The Evolution of the Flash Security Model
Peleus Uhley, Senior Security Researcher, Adobe

View the video

The Adobe Flash Player security model must address several complex challenges. Flash Player must meet the needs of enterprise administrators, end users, Web site owners, and content creators. The model must adapt and scale as improvements are made to Web standards. As a technology, it is deployed across multiple browsers on multiple operating systems. Those operating systems may be installed on desktop PCs, mobile devices, tablets, or digital home devices. Most important, Flash Player must provide a security model that is consistent for everyone regardless of the combination of browser, OS, and device they are using.

This presentation will discuss how Adobe is addressing some of these complex challenges through real-world case studies. It will begin with a few past events that resulted in significant changes to the security model. The discussion will then progress to our more recent changes and what factors are currently influencing us. The presentation will close with some thoughts on the challenges that lie ahead as the Web expands from the desktop onto mobile devices, tablets, and TVs.

Understanding Scam Victims: Seven Principles for Systems Security
Frank Stajano, Senior Lecturer at the University of Cambridge, UK

Listen in MP3 format

The success of many attacks on computer systems can be traced back to the security engineers not understanding the psychology of the system users they meant to protect. Paul Wilson and I examined a variety of scams and short cons that were investigated, documented, and recreated for the BBC TV programme The Real Hustle and we extracted from them some general principles about the recurring behavioral patterns of victims that hustlers have learnt to exploit. We argue that an understanding of these inherent human vulnerabilities, and the necessity of taking them into account during design rather than naively shifting the blame onto the gullible users, is a fundamental paradigm shift for the security engineer which, if adopted, will lead to stronger and more resilient systems security.

Vulnerable Compliance
Dan Geer, In-Q-Tel

View the presentation slides

View the video

If a basic interoperability constraint, such as a core, standardized network protocol, has a flaw, then everyone who is standards-compliant will be vulnerable. What, then, does one do? If the flaw is long-standing, then by now it is pervasive, embedded in robotics, and likely to be in silicon. If the protocol is touchy, then seamless updates may not be possible. If a repair is possible but field deployment can be expected to have a half-life measured in months if not years, what does that imply for security policy? In the particular case of embedded systems, does this mean that remote upgradability—with all the risk such a capability entails—is a wise design choice? In the case of core Internet protocols, does that mean that Jon Postel's famous Robustness Principle, viz., to be conservative in what you send and liberal in what you accept, is no longer consistent with security? Is there an analog to perfect forward secrecy when it comes to planning for protocol failure the way we already (can) plan for key loss? With luck, this talk will at least ask the right questions.

How Cyber Attacks Will Be Used in International Conflicts
Scott Borg, Chief Economist, US Cyber Consequences Unit

View the presentation slides

Every international dispute, if it becomes intense enough, is now likely to have a cyber component. Civilian cyber militias have become a regular part of regional conflicts. The resulting cyber campaigns now have the potential to escalate dangerously, to spread across multiple countries, and to disrupt global supply chains. Meanwhile, governments have become increasingly aware of the contributions cyber attacks can make to military operations. Drawing on a detailed examination of recent cyber conflicts, this session will attempt to survey all the ways cyber attacks are likely to be used in international conflicts in the near future. It will explore the pros and cons of each option for both civilian and military efforts, all the way down to the operational level. It will present some novel analytic methods that allow many of the choices to be quantified. Finally, the session will identify some of the ways these developments are likely to change the world in which we all will be operating.

As technology developments continue to make the electric grid "smarter," many believe security–and particularly cyber security–has become an afterthought in many respects. What does this mean to those trying to keep the lights on? What kinds of threats face the grid today? What makes the grid unique from a critical infrastructure perspective? What are the regulatory and policy drivers behind the push to make the grid smarter and more secure? This discussion will attempt to answer these questions and shed light on the current state of smart grid developments and grid cyber security throughout North America.

End-to-End Arguments: The Internet and Beyond
David P. Reed, MIT Media Laboratory

View the presentation slides

View the video

A key factor supporting the Internet's evolution and growth is the use of "end-to-end arguments" to decide where to place functionality in the overall architecture as it evolved. There are many today who assert that the end-to-end arguments are no longer applicable to the Internet—that the Internet in its maturity must now begin to lock in specialized functions for mobile phones, television and video conferencing, functions to enable cyberwarfare, and functions that are required to ensure adequate profits to the operators and equipment vendors who must have incentives to invest in the Internet. At the same time, we are seeing vastly more complex interoperable architectures built around the Internet emerging in the form of cloud-style computing and mobile interaction.

Dr. Reed, who is one of the three authors who articulated the end-to-end argument as a principle of design, will argue that the end-to-end argument is not dead—it is more important than ever. In passing, he will explain some of the misconceptions about the end-to-end argument that have emerged from its friends and its foes.
